Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.

HAVE TRIED CHANGE THE CMOS BATTEWHAT CAN I DO NXTRY TO REMOVE BIOS PASSWORD BUT IT COUDNT WORK,?


Sony Vaio PCG and some Vaio VGN Series use the last 7 digits of the laptop serial number to calculate the bios master password. The serial number for a Sony Vaio is often located on the bottom of the laptop on a white sticker. The serial number may also be found by removing the battery and checking in the battery compartment. The link to unlockbiosrecovery.com below works on the following models:
PCG-C, PCG-F, PCG-GR, PCG-GRS, PCG-GRT, PCG-GRV, PCG-GRX, PCG-GRZ, PCG-N, PCG-NV205, PCG-QR, PCG-R, PCG-SR, PCG-SRX, PCG-TR, PCG-V, PCG-VX, PCG-X, PCG-Z, VGN-B, VGN-FS, VGN-S, VGN-T, VGN-TX1, VGN-X
I use http://www.unlockbiosrecovery.com/Unlock_Sony_Bios.php
For $20 they use the last 7 digits of the laptop serial number to calculate the bios master password and then email it to you in an hour. They guarantee it to work and you can call them if you have a question.

My vga card for sony vgn-t2xp model pcg-4d1m


The model of your sony vaio is VGN-T2XP/L and chassis type is PCG-4D1M

I can only give you a link where you can download necessary drivers, updates/firmwares or original drivers that comes with this unit. It depends on what operating system you are currently using.
If you then upgrade your operating system for example from windows vista to windows 7, then suddenly some hardware including sounds, lancard, vga experienced some troubles, I do suggest you downgrade again your operating system or find appropriate compatible drivers that will work for your new operating system.
In this link you will find something that might help you.
