Will not turn on, power comes in from "brick" power supply.
I took laptop apart and cleaned it, and while handeling the "power button assembly" it came on.
It worked fine for 3 days then died again , took it apart again and fiddled with the Power button assembly again , it started briefly and made a nasty "something is hitting the fan" noise and turned off.
I dissasembled it completelly and found a loose piece of CPU heat sink , Removed it and re assembled it .
But It is completelly dead , It behaves as if power is not present but there are 9V at the jack.
Is it possible that the "power button assembly"( a small board with 3 buttons, connected by a multyconductor cord to the board) is faulty?
ECS wants to sell me a new motherboard.

1. power adaptor which should have an OVC of 19-20v in order to charge the battery of 14.8v.
2. while you clean the button, you trigered the power supply circuit within the motherboard. as I suggested to Clinta74, it is the 1500uF6.3v capacitor(s). it is very bad indeed, but not completely dead, so it might start briefly.
since you know how to fiddle with the heat sink, you probably have alread reached the bare motherboard. Check that the caps first.
Yes, try replacing the power button assembly first and the heatsink assembly and fan before shelling out big bucks on a Mobo (which is probably pulled from another LT).

Hi there. The laptop has to be taken apart and a new power supply adapter that fits that model soldered on to the motherboard, you will also have to order the replacement parts first. The keyboard will probably need replacing, the part number is underneath the keyboard so you will have to remove the keyboard to view it. You can get a power adapter socket from sites like ebay, you will have to search for this part by laptop make and model and is fairly inexpensive to purchase. Replacing these components will give the laptop new life so if your confident with a soldering iron and know what to do around a laptop motherboard you know what parts to chase. If you feel your not that confident, you have the option of phoning a reputable PC repair shop and ask them if they can do the repair on the power adapter instead of buying a replacement motherboard, if they can have it repaired by them and also maybe they can do you a deal on a replacement keyboard.
then you need to replace it.
