My GF kindly brought her laptop over and told me that it will not turn on. Used to her inability to use technology I nodded my head in sarcastic agreement.

I opened it up plugged it in and turned it on and sure enough she was right, it would not turn on. The power adapter indicator LED on the laptops front was on (so power coming into the computer) it just wont power up at all. Its like it has no power and no battery..

So what is the problem?

Surely its not a failure of the PSU otherwise why would the actual LED on the computer indicating the adapter is connected?? Any reccomendations before I head down with my VISA (shames shes so pretty :P)

Have you tried removing both power and the battery, left it off for a min then tried plugging the power back in?

Thanks for the tips guys!! I did some reading into the late hours of last night and like suggested here removed the battery and power plug overnight. Just pushed the start up button and its started up as per normal. Guessing the CMOS was corrupted and this reset it?

Cheers again - itxtme

The pc company i work for is a toshiba repair centre, we see that all the time. Just removing the battery and powering on fixes it. dont quite know why it happens but it does, especially for the older model laptops, havnt seen it in a new one yet.

Lol in the holidays I was visting my grandma and her laptop had the same problem. Looked at it, no power going into the laptop, took the battery out, plugged the power cord in and it would then power up and start. Then I pluged the battery back in and it was fixed. Took me one minute and my grandma was impressed :P. My flash technical skills own. Works on tv remotes and toys too :P.
