Thinkpad T500 not booting after battery drain windows 7


Thinkpad T500 not booting windows  after complete battery drain and  looping back to Thinkvantage screen.


Try plugging in the power cord and try to boot from Windows DVD or from USB using Ubuntu , if your thinkpad is still not able to boot windows from HDD then there should be something wrong with BIOS.


To go to BIOS restart your laptop, press DEL when you see the Thinkvantage screen, now to go to BIOS
Look for Config --> Serial ATA(SATA) --> SATA Controller Mode Option and change it to Compatibility from AHCI and restart.  Now press F12 at the thinkvantage screen and try to boot from HDD or DVD to resinstall Windows 7 if the windows 7 start up tool doesnt resolve the issue.

If the issue still persists and your laptop still doesn't boot then refer to below post
