you are the man. that fixed it! thank you

Thank God it worked for me too. I was having the same problem, Sony Vaio PCG-V505BX working one moment (no battery problem or any other issue for that matter. The next day it was dead in the water, no boot, no power, no nothing. I disconnected & reconnected cmos battery located under keyboard. This reset cmos or something. The first boot there was a bios beep, I had to reset the clock, now everything is fine. Thanks, bent

POWERLESS PCG-V505BX powerless - 2nd Nov 2006 21:41 same problem. it's really freaky. it just happened about two weeks ago. can you tell me how to take the keyboard out?

Thank you. This worked perfectly. I opened the keyboard and took the CMOS battery plug out. Waited about 15 minutes and put everything back together. It came back to life right away. PS: I also pushed the power on button for 15 seconds to drain the PC, as was suggested in another forum.
