Screen is black


It sounds like the backlight of the LCD display is out. The Image is still being displayed there is just no light to illuminate the image. Try shining a flashlight on it (Put the light right against the screen) and see if you can see what's on the screen. The display is fairly easy to install but I do not know where you can purchase one directly.

The issue may appear due to several reasons such as Windows Update or any recent hardware or software changes in the computer.

1. Please reset the BIOS to default values.

2. Try booting the computer to Windows in safe mode by pressing the F8 key at startup.
3. If the issue persists, please check if the hard drive is listed with its volume (size) eg: 500GB in the BIOS main menu. Press F2 key at startup to enter BIOS.
4. If the hard drive is listed, perform a system recovery using the recovery console/partition by pressing the F10 key at startup.

5. If issue persists, please use the recovery discs or contact the sony service team to get the computer repaired.
The issue may be related to the operating system files. Getting the recovery partition re-imaged will be the best possible resolution.

No sreen after startup window


Boot your system into safe mode and reduce the resolution to your monitor. It is set to high and blacksout because of memory. Besure to use F8 in order to enter safe mode before windows start.
Good Luck

How do I re-format a 2x serial SATA drive to reinstall XP?


How to Format a Hard Disk

After you create the partitions, you must format the partitions:

Restart your computer with the Startup disk in the floppy disk drive.

NOTE: If you are using a Windows 95 Startup disk, a command prompt is displayed and you can skip to step 2. If you are using a Windows 98, Windows 98 Second Edition, or Windows Me Startup disk, select the Start computer without CD-ROM support menu option when the Windows 98 Startup menu is displayed.



2. When a command prompt is displayed, type format c: /s and then press ENTER. This command transfers the system files and should only be used when you format drive C (or your "active" drive). For all other partitions, type format drive: (where drive is the letter of the partition that you want to format).

NOTE: If you receive a "Bad command" or "Bad file name" error message, you may need to extract the Format.com tool to your boot disk. To do this, type the following command at a command prompt, and then press ENTER:


Extract ebd.cab format.com

After the Format.com tool is extracted to your boot disk, type format c: /s t a command prompt to format your active partition, or type format drive: if you want to format a partition that is not your active partition.

3. When you successfully run the Format.com tool, you receive the following message:
WARNING, ALL DATA ON NON-REMOVABLE DISK DRIVE C: WILL BE LOST!
Proceed with Format?


4. Press Y, and then press ENTER to format drive C.

5. After the format procedure is finished, you receive the following message:
Volume label (11 characters, ENTER for none)?

NOTE: This is an optional feature that you can use to type a name for the drive. You can either type an 11-character name for the drive, or you can leave it blank by pressing ENTER.

Tablet CX 2620 Display problems


You should angle the screen towards the light to see if you have a faint image on it. If so, the problem is more than likely a failed inverter, or CCFL lamp on the LCD itself. Either in which would have to be replaced. The CCFL lamp unfoutunatly part of the LCD it self and cannot be replaced seperate the screen. The inverter can be replaced easy as it it right under the screen. Symtoms of a failing CCFL could be the white comes out as red on the screen for the 1st 10 sec or so of startup. This will put alot of stress on the inverter causing the inverter to overheat and shut off. I have one to where the CCFL failed and am trying to find a replacement.
Good luck
