Hi all, first post and I've got a problem with a laptop, a toshiba u300, I hope you can help me with.
I have little electronics knowledge, but am willing to learn.
The problem is, the laptop will not turn on unless I remove the power adapter and battery and hold the on button for about 20 seconds, the laptop runs fine then but every time I turn it off it doesn't start again, it's dead, no lights no nothing, I have stripped it down and have found that if I remove the battery and put a voltmeter on a capacitor, it reads 12v then goes quickly down to around 2v, then the laptop will boot.
The battery has 9 connections, I have found that when the laptop will not boot, 2 connections have 12v all the others have zero, when it will boot, 2 have 12v, 1 has 0.2v, 2 have 3-4v.
So with my little knowledge it seems static electric stops the laptop from booting, I don't think it's the battery as I also have the problem using just the power adapter.
I hope you understand my rather long problem and can give me some idea of what can be the cause.
Thanks
