Sony U Background Information:
The Sony VGN-U50 and VGN-U70P was, at its release on May 30, 2004, the smallest personal computer running Windows XP and most powerful high-end Palmtop available at the moment. It is smaller than two DVD cases stacked on top of each other. At this small size you have the power of a Pentium-M 1 GHz with a 800x600 passive touch screen (which can be manipulated with a finger and any type of stylus) , internal 802.11g Wifi, sound, trackstyk, and the expandability through a Compact Flash and a Memory Stick slot, and a small docking station that can be used to connect desktop peripherals like a large LCD, printer, keyboard and mouse, and other USB 2.0 and Firewire devices such as DVD dual layer burners.
There are six different variants of the U series, varying on CPU speed, memory, hard drive capacity, and area availability. The first of the series to come out was the U50 and the U70P in Japan. The American model is the U750P. A U8G model was introduced for some south Asian countries.
With the extended battery, the U series can operate 5.5 hours without being recharged and can operate for almost an entire day using Standy and Hibernate mode. Instant on operation can almost be achieved by using Windows Standby, requiring just under 3 seconds for the U to be fully operational.

Considersations Before Buying uPC - Handtop:
Sony U Maintenance
Thumbstick wear
There have been several reports that the U thumbstick becomes sticky and breaks off.
Replacement caps are available from Sony for $29/pack. (message 5210 at YahooGroups)
The cap sensor is the correct part for replacing the white part of the trackstick.
The part number for the cap sensor is 4-681-950-01 and it costs $7.22 USD plus tax & shipping.
Sony parts:
link or 1-800-488-7669
The pointer is one assembly that consists of a circuit card with a plastic track point.
The exposed parts are listed as two different part numbers. It isn't clear from the picture what these two are, but the "cap" appears to fit over the end of the track point stick and the "cover" a part that sits over the "cap". Thus it would appear that the "cover" is the part with the white rubber center.
Regular glue does not fix this.
Fix: Replacing the cap sensor requires significant disassmbly of the unit; however, it is a simple operation once the U is opened.
Quick Fix: A fix report was made that did not use the replacement part and no need for disassembly. Remove the chrome ring and the lower rubber parts (which deteriorated) and clean out the sticky green stuff. Then I simply put one of the black Sony U101 thumbstick tops onto the bare brass pointer rod. These fit well, as if this part had been the originally intended configuration. The style is different than the OEM thumbstick, but it provides better feeling and control
than the original thumbstick, probably because of a more rigid finger/thumbstick coupling.
*The thumbstick is not the cover sensor, which is the round silver piece.
Service Manual
Is available for $7 from Sony (message 5212 at YahooGroups)
Firewire CDrom Boot Issue Resolution
If you remove the battery from the back of the U, there is a small pinhole (for a paperclip). Stick a paperclip in the pinhole and this will reset the bios settings. Depressing this button has allowed several users to boot from their PCGA-CRWD2 or PCGA-CRWD1 devices.
Screen Issue
This issue has been reported only a few older machines, but, once appears, manifests very quickly and appears to be heat related. After waking from hibernate mode, the screen acts strangely--the screen goes sort of grey with a scrolling white line that leaves a trail behind it or the colours start to look like a negative image. Users report that they never turn off the U, instead using hibernate mode, so the unit would become quite warm. Sometimes, a little pressure on the unit makes the screen issue go awaym but only for a minute. When the U is turned completely off and cools down, the problem disappears.
Resolution: Replace the screen.
Temporary fixes: Turning the machine off instead of putting it in hibernate mode also helps because it lets the U cool. Appyling a little pressure to the top of the device also seems to fix it.
Sony U Repair:
For U750P: Call Sony USA
For any other model:
Repair Option 1: One must go back to the country of origin where that specific U model was sold.
*You're out of luck if you are not in the country of release and do not speak Japanese.
e-mail-- sales
chiby dot com contact-- Mizoe-san
*Greyhat has no relationship with Chiby, but there are various positive reports at YahooGroups (message 5554) and they are a well-known and trustworthy Japanese import technology company.
Repair Option 3: A single positive report has been filed at YahooGroups to Laptopteks in Florida (message 5597).
The YahooGroups reported that a U that wouldn't power up cost $250 plus bi-directional shipping.

More information on older U models:
THE REST OF THIS GUIDE WILL BE DEDICATED TO THE CURRENT SONY U MODELS
Sony U Facts:
- The U is not pocketable, but is ultraportable and powerful enough to be a notebook replacement.
- All U-series models look the same, have the same dimensions, and have the same weight.
- The 5" screen is surprisingly crisp with readable fonts (standard PDA screen is 3").
- The U screen is brighter than the OQO 01/01+ period (we own both devices).
- Transreflective screen excels in sunlight, office light, and in the dark, with or without backlight.
- Native screen resolution is 800x600 for all models with a 4:3 aspect ratio.
- External monitor screen resolution is 1600x1200 using the docking station or the included VGA/Ethernet adapter.
- Can be used in multi-monitor mode and in dual display mode.
- Passive touch screen (Gunze) does not require a stylus and can be manipulated with a finger (similar to a PPC/PDA).
- Built-in portrait and landscape viewing modes (screen rotation) using built-in U hardware button.
- Screen rotation works for various games such as MAME.
- Hardware buttons can be reassigned using Sony Notebook Setup or by
vaiouup_e.exe (able to map the button in one way automaticaly when you launch an application A and in a totaly other way when we launch an app B).
- Built-in resolution zoom option from 640x480 to 1600x1200.
- Integrated 802.11b/g wireless card has very good reception.
- There is no integrated keyboard, making the Sony U-series more of a PDA/PocketPC-style device or a mini-Tablet when XP Tablet Edition is running.
- Sony does not offer the option to install XP Tablet Edition on the Sony U.
- Allows convenience and portability to leave the keyboard and CD drive behind if you do not intend to use them.
- No built-in microphone or microphone jack. If needed, an external USB microphone adapter or USB microphone is required.
- For video conferencing, integrated camera and a microphone USB Webcams are available.
- No built-in Bluetooth. If needed, an external USB or CF Bluetooth card is needed.
- No built-in modem. If needed, an external USB or CF modem card is needed.
- No PCMCIA slot.
- The PCMCIA controller that runs the CF Slot is Cardbus, although U Cardbus cannot be used because the CF interface is only 16bit.
- A CF-to-PCMCIA adapter will allow 16bit PC Cards to function in a U.
-
Test results show that there is essentially no difference in CPU performance between the U50 and the U70P, where the only difference appears when running multiple applications and the additional 256MB RAM in the U70P assists performance.
- Hardware scroll keys are 4 way only.
- Hardware scroll keys are the only hardware keys that will bring the machine out of standby; turning on key-lock will disable this.
- Center "enter" button in the middle of the hardware scroll keys is hard to push without clicking on a direction as well, you have to use a thumbnail to use this key.
- Sony docking station does not work without power.
- The first button on the docking station is for Gigapocket Video Download Manager.
- The Firewire (1394) port is located on the docking station only and is an unpowered 4-pin Firewire port.
- U70P should have slightly better battery life than the U50 because its Centrino CPU uses less power when on "idle" and "sleep" modes.
- U750P should have slightly better battery life than the U70 because the Dothan CPU is more efficient and uses less power than the Centrino.
- To get a feel for the overall size of the Sony U-series, fold an 8.5" x 11" piece of paper to one quarter of its size and add 1" to the length.
- The U1, U3, and U101 are a completely different type of larger Sony U device with an integrated keyboard.
- The Sony U cannot be charged via the USB port.
Assumptions with U use:
- Sony makes excellent gadgets, but they come at a price, gadgets and accessories are very expensive, and parts may be of limited supply.
- In order to use the U and unlock certain features, it's best to have a Sony Firewire, PCMCIA, and USB CD or DVD drive.
- Sony products are made for the fast-paced Japanese market, do not expect U models to last more than 6 months and U accessories to be available after 1.5 years.
Sony U Model Notes
The Sony U50, U70P, U8G, U8C, U750P, and U71P models all share the same accessories:
- Lithium-ion Battery (VGP-BPS1 and VGP-BPL1)
- Cases
- Stylus and strap (A-1074-714-A) $62.95
- Docking station with port replicator (VGP-PRU1) $230
- VGA/Ethernet dongle
- AC adapters (VGP-AC16V7 - Sony tip 16V) $50
- Fold-up USB Keyboard (VGP-KBC1) $220
- Remote control and headphones (RM-VSC1)
- Multi-pointer replacement caps for the keyboard above
- XP drivers
*Sony software is device locked, so application recovery CD drives for the U750P will not work for any other model. There are hacks, but Sony has done a good job in making extraction efforts difficult. Greyhat has seen successful Sony application CD extractions for Sony Picturebooks.
**The performance of the U50 appears to be similar to the U70 where the additional 256Mb memory difference of the U70 provides a performance advantage over the U50.
Sony U FAQ:
It is a known occurrence that the multi-pointer cap breaks on the Sony U (search Yahoo Groups: Cap broken off multi-pointer) as the cap is held on by a green gel. If the Sony U is under warranty, Sony will fix the unit, but it has to be shipped to them. The cap can be held in place by using some type of silicon glue or gum ;) .
Greasy look on screen, bubbles under screen film, condensation in the screen, and any dark spots in the screen indicate a problem with the touch screen. The Sony U screen needs to be replaced. Typical cost is $800 for the Sony Service department to fix the U.
DIY Issue: Thumbstick becomes sticky and basically wears off.
Fix: Remove the white rubber completely and clean it out. Then increase the sensitivity. It'll work ok (thought not as
well as before).
Configuring the Sony U CPU Speed/Performance
Start --> Program Files --> Sony tools -->VAIO power management --> VAIO power management viewer
Select Advanced
Change the system's thermal control and performance should increase as temperature is increased (the hotter it is, the faster it goes)
Sony U Input Methods
Since the U does not have a built-in keyboard or thumboard, alternative input methods are required in order to use the Sony U.
Input Methods (listed in order)
1. USB Keyboard
Since these are not integrated to the U, a desk or other flat surface is required for typing. Couch or lap-only use (or Errr...bathroom use) is difficult with this accessory.
- Sony U OEM USB foldable keyboard
- Fellowes USB foldable keyboard
- Other USB foldable keyboard
2. Hand Writing Recognition (HWR)
Learning is required and has recognition accuracy around 95% at best and 90% on average; therefore editing is required to ensure proper input. Input of mixed case, numeric, and symbols (e.g. inputing a userid and password) is very diffifult using this input method. HWR also allows one to use the U in one hand, use the touchscreen or HWR with the other hand and can be used at a desk, on the couch, or on the "thrown". Both HWR software packages are excellent, although all reports and personal experience proves that XP Tablet OS HWR is superior.
- Windows XP Tablet 2005 (XP SP2) is excellent and free with the operating system. There have been comments about performance issues, but we have not experienced "performance issues" running Tablet. XP Tablet OS is expensive and requires an MSDN license.
- ritePen 2.5 is an excellent XP companion and worth the additional money for the U50, U70P, and U71P. ritePen 2.0 comes with the U750P (only English model), but the upgrade to 2.5 is worth the money for more accurate input and for editing.
3. Bluetooth Keyboard
This is another keyboard. Input accuracy is good. The pitfalls to this device is carrying around another device roughly the size of an OQO with the Sony U for input, pairing of Bluetooth (there may be drops), and battery life (as this device requires its own power).
- ThinkOutside BT Foldable Keyboard
4. USB Thumboard
This device is almost too small, missing essential keys for "full" keyboard or thumboard use, is a standalone thumboard and does not have an attachment for the U, and does not have sticky keys (e.g. performing CTL-ALT-DEL is like playing Twister with your fingers...it's a gymnastic effort).
- dreamGEAR MINI-key USB Thumb Board
5. Voice Recognition (VR)
Learning is required and has recognition accuracy around 90% at best and 80% on average; therefore editing is required to ensure proper input. Input of mixed case, numeric, and symbols (e.g. inputing a userid and password) is almost impossible using this input method.

Sony U50 Memory Options
The additional 256Mb memory for the U50 only sold in Japan and costs $400 (the difference in the retail price of the U50 and the U70P).
*If you are a U50 owner looking to upgrade your memory, you need to find a supplier selling the OEM Sony U memory. Perhaps we can get a importer helping the U50 owners?
Looks like Conics.net is selling the Sony U 512Mb memory module for $426:
link
The Sony U50 and U70P do not use a SODIMM connector, they use a stacking connector.
Photo of the Sony U memory module: Here
NOTE: The problem in finding memory for the U50 is that it is unclear that any other device uses a memory module with this sort of connector for there to be 3-rd party suppliers. (Thanks A.Anuff)
****DO NOT buy the memoryx.net memory below (Yahoo Groups message 4684 indicated that this company gave a U owner a hassle for returning the inappropriately listed memory).
The following website (
memoryx.net) claims that they sell the elusive memory upgrade, but Yahoo Groups users have reported that this memory
does not work with the U50:
link -Additional info added regarding non-compatible memory upgrade from memoryx.net - (Thanks R.Cohen for buying it and verifying that this memory does not work with the U):
"I bought one anyway to try, and I can confirm, the memory module sold by MemoryX does not work with the VGN Ux Vaios. It is completely wrong, not even close. The SODIMM is significantly larger (like, nearly 1/2" too large) than the space provided in the Vaio, and the edge connector is totally wrong, besides.
Note, I did a search of the U70 group on Yahoo and wasn't able to find any comments one way or the other regarding this memory. You should update your web page to reflect the information provided above. The comment as-is will probably lead others to waste their time and effort giving it a try, too!"
We have not confirmed whether or not the following sites offer the 256Mb memory upgrade for the U50:
*If any one would like to try them and report back to us, that would be appreciated.
- satech.com (appears to only sell Compact Flash memory for the U50)
- kahlon.com is not clear on whether they have the special U50 memory
***WARNING***
Arch Memory (below) DOES NOT work with the Sony U and Greyhat has a confirmation that Arch stands behind their memory guarantee (good job Arch for being honest).
"The archmemmory for the Sony u50 which is listed on the Greyhat site does not work. The connecter is on the end and not on the bottom like the Sony ram. Just wanted to let you know so you could update the site." - J. Rhodes
062103 Update: "ArchMemory has given me a complete refund including the original express shipping costs for the incorrect Sony U memory. They stated that Sony gave them the wrong specs." -Jon Rhodes
- DOES NOT WORK: Arch Memory appears to guarantee their memory and claims to have the memory available for $128.99: link

- DOES NOT WORK: 1gb memory for U50, U70, U71, U750 from NotebookdrivesOutlet: link
Several suppliers have claimed that the U50/U70 can use the same "Micro-DIMMs" that work in the PCG-U101 and the Panasonic R2, which is incorrect.
The module on the page you linked is just a standard SO-DIMM, used in regular full-size notebooks. No way will it fit in the U50. The U50/U70 etc. use a special RAM
module (not a DIMM) that AFAIK is not used in any other device. -C.Ferebee
Standby, Hibernate, Power-On Information
Instant On (Similar to the PocketPC and PDAs)
U70 running XP Tablet Edition 2005 (SP2)
Bootup time (through auto-logon): 1 minute 41 seconds
Wake from Suspend (Standby): < 2 seconds
Go to Suspend: ~3 seconds
Wake from Hibernation: ~10 seconds (in /out)
Standby and the Docking Cradle
Standby and the docking cradle have been proven to work in 2 modes:
1. U can be running and removed from dock without issue.
2. U can be placed in Standby while in dock, later removed and unsuspended, and the U resumes without issue.
*In general, it is safe to put the Sony U into standby and then remove it from the docking station, power it back up, use it, return it to standby, return it to the docking station, and then power it back up.

Stylus
The Fin Stylus that comes with the Sony U is interesting, but feels awkward so you will most likely replace it.
The Sony U-series does not have a stylus slot.
The U-series stylus is attached to a lanyard through an available eyelet on the top, right and left corners of the U.
Any PocketPC or Palm PDA stylus can be used on the Sony U touch screen.
Lanyard
There are 2 lanyard posts on the top right and left of the U.

***When the U is in hibernation, the battery can be replaced without AC power.
****The Sony U cannot be charged via the USB port. You must use a power supply.
Battery Life

**This is a good article to prolong the life of the Sony U Lithium-based battery:
link
All rechargeable batteries have a finite number of charge-discharge cycles.
For Lithium-ion batteries, half charging is better for the battery than full charging.
For the Sony, it has been suggested that it is best to keep it on AC whenever possible and never run all the way down.
Battery Life Comparisons
The Sony U standard battery is only slightly better than the OQO standard battery.
Although the Sony has an extended battery which should effectively double the mark to 326, which is close to 3x the OQO. OQO does not have an extended battery.

Overall, the operation was simple and was able to reuse the 20Gb U drive in the iPod. The user reconfirmed his experience in post 4590.

Detailed Steps to Replace Hard Drive
*Read the Disclaimers below
There is very little you can do to make more room inside the U and very little you can do to the drive to slim it down. After this operation, there will be a small gap from the bulge of the larger drive in the side gasket of the U.
Recommendation: Use a piece of shipping tape with the sticky side up to keep track of the screws and their relative place on the U (make sure that you place them on the tape in roughly the same position that they came out). This will help you when you go to put it back together.
Instructions for the Toshiba 60GB MK6006GAH Hard drive replacement:
1. Remove the battery and all of the first screws are underneath.
*With the battery removed there are screws with arrows pointed at them (similar to most other Sony hardware), indicating they are the ones to be removed for servicing.
2. Remove all of the screws from the bottom of the U.
3. Remove last external screw from under a small label with Japanese writing on it.
4. Take bottom panel off.
5. Carefully remove the side gasket from the bottom of the U.
- The gasket is one piece and goes around the entire edge of the U with the power connector going through it.
6. Remove the screws holding the bottom circuit board.
7. Disconnect the two ribbon cables running from the bottoms the circuit board by lifting up the quick release connectors and pulling the cable out.
8. Move the bottom circuit board outward so that you expose the hard disk drive.
9. Remove the screws holding the cage that holds the hard drive.
10. Remove the hard drive cage.
11. Slide the hard drive away from the motherboard pins.
12. The drive will have a rubber insulator on each edge. Since the drive is thicker, the insulators have to be left off.
13. Remove the cover on the new drive over the drive's circuit board.
14. Install the new drive into the connector.
15. Insulate the drive from the hard drive cage using a piece of rubber (reuse a portion of the brown rubber insulator).
- Since the insulator is no longer holding the drive off of the Sony's circuit board, the drive will sit lower against the Sony
than the original drive.
- This is necessary because the larger drive has a raised portion where the second hard disk platter is that sticks out
of the cage holding the drive to the U. This raised portion sits against the back of the LCD panel, so you want to get it as close to the Sony as possible.
Additional Pictures of Replacement Procedure:
*Review Sony U70 Autopsy pictures above.
**This operation is not for the faint of heart and requires some finesse.

- The Sony U provides ample power to drive most USB 2.0 and 1.1 hard drives in enclosures.
- Since the Firewire port is only available on the Docking Station, we recommend a USB 2.0 external hard drive solution.
- The cheapest option for external disk is to purchase a USB 2.0 2.5" enclosure and a 2.5" notebook hard drive (5400 rpm hard drive)

Report: Sony U Compact Flash Has Slower Performance Compared to USB 2.0 Card Reader
"The CF slot bus speed is slower than the USB 2.0 port and a USB 2.0 card reader.
Transferring a 4Gb MPeg2 movie from my Microdrive to a server on my network was slower using the CF slot in the U than using a card reader and the USB2 port.
The same 4Gb MPeg2 video was transferred for the "test" from the same Microdrive.
The transfer time for (roughly) a 4Gb file with the Microdrive inserted in the Sony U CF slot is 54 minutes.
The transfer time for (roughly) a 4Gb file with the Microdrive inserted a USB2 card reader connected to the USB2 port of the Sony U is 23 minutes.
The only difference was the CF slot was used instead of the the USB 2.0 reader."
Firewire (IEEE1394/iLink)
- Sony iLink is Sony's version of Firewire.
- The Firewire ports are located only on the included Sony U Docking Station.
- When connected to a supported and powered optical drive, the Sony U can be booted using a Sony compatible drive.
- Sony iLink uses a 4-pin unpowered Firewire port.
- Normal Firewire ports have 6 wires, with 2 wires for power and 4 wires for data.
- The iLink on the Sony Docking Station has extra pins for power, but they will only fit a special cable that connnects to specific proprietary Sony iLink DVD and CD drives.

USB Thumboard:
- Recognized as a Thumb Board on the U
Notes:
- Provides an add-on keyboard to the U
- Almost too small with the U but inexpensive
- Fairly cheap plastic feel
- No sticky keys, so Windows button (remapped) + anything is a 3 button acrobatic move
- One needs to hold the U
and the MINI-key, needs stand like the
Multipivot (above)
*Use ZDnet
Tradekeys2 (formerly ZDKey) or SharpKeys (below) to remap thumboard keys to remap missing keys.
Tradekeys2 key mapping:
F6->Windows key
F7->Ctrl
F8->Alt
F9->Del
F10->Escape
You cannot perform the Ctrl-Alt-Del function, but there is a reset button on the U for this. Two-key combinations such as Alt-F4 work. With these mappings, Alt-F4 is: Fn+F8+F4 (all at the same time, just make sure to hit Fn+F8 first).
*The biggest problem with this thumb board is that the Function and Symbol keys are not sticky (they must be held down in order to access the Function/Symbol keys). In order to use the mapped CTL key to perform CTL-C (copy), one must depress the Fn key while also depressing the F7 and C-key (a thumb twister). Some have reported that they are use to this with other thumb board devices such as the BlackBerry or SideKick. While using this very tiny (almost too small and thin) device, one must determine the most ergonomic and feasible way to hold the Sony U.

Sony U Input Methods
Onscreen Keyboard Options:
UBoard v1.0:
UAddict - Nostram Studios UBoard Transparent Fullscreen Fingerboard for the Sony U series:
UBoard is an on-screen, transparent keyboard that is specifically designed for the Sony U with keys large enough that allow typing with the fingers. The keyboard is attractive and responsive and very easy to use. UBoard autosizes to fit the width of the screen and works in both portrait and landscape modes. UBoard also has a user configurable transparency level, so even though UBoard is filling most of the screen you can see right through it.
*Flaw of this software is that there is no sticky key function, in that the multiple key presses are impossible with this keyboard (e.g. CTL-ALT-anything is not feasible).
With the help of jk, Nostram Studios (aka Pete, UAddict, and Digitized Life) has allowed Greyhat to provide an alternative download location for the donationware UBoard:
*Greyhat does not support this software, please refer all questions to the appropriate forum. Digitized Life posts at
Yahoo Groups, so we suggest that you post issues and enhancement requests for UBoard there.
**No explanation has been given for the UAddict site outage.
UBoard Installation Software Requirements:

Hand Writing Recognition (HWR):
XP Tablet Edition
*In ritePen there is a "use separate letters mode" setting in the recognizer menu. This will help write mixed things that don't appear in the dictionary like "3L33T K1D5.#". Words like this can also be added in the dictionary. This all comes with a word of caution as modern convention independent HWRs like TabletPC or ritePen rely on lexical context to recognize things. None of the HWR are going to recognize the '1' in K1D5 as a 'one' rather than a lowercase 'el' unless the lexical context predicts it.
Voice Recognition:
*BT headsets are not recommended for voice recognition by eMicrophones.com:
link
Bluetooth
This is a missing integrated feature in the Sony U and needs to added through the Compact Flash slot or USB port.
* Many people have reported problems with simultaneous use of the Think Outside Stowaway keyboard and Think Outside Bluetooth mouse. If you use the Think Outside Stowaway keyboard and a different BT mouse, you should be fine.
** The Billionton BT CF card appears to be the most universally interoperable BT CF card, the Ambicom has been reported to mostly work with various BT peripherals, and the Socket has been reported to have the most interoperability issues with devices such as the ThinkOutside BT Foldup keyboard, headsets, and headphones.
*** The BT USB adapters have had the most success functioning on the U with various peripherals, costs less, and sticks out as far as the leading CF cards.
