I am having problems starting my 3,5 years old ThinkPad. Previously everything worked fine, except overheating issues, which were kinda solved by using TP fan control. Emergency shutdown was a normal behavior for my laptop. There was no problem to start work all over again after it cooled down. However, one day, after a simple web-browsing my ThinkPad started to work really slow and then shutted down.
Unfortunately, it did not turned back on as always, instead a black screen, solid power lid and spinning CPU fan is all I get. Also, HDD give some signs of being alive, as it spins too.
I have already tried to unplug AC adapter, remove battery and connect to power source again; a trick with power button pushing to make a static discharge. Nothing of it helped.
I have a few thoughts on this: Bad power supply (laptop was using AC adapter as only power source for a while, after battery live came to an end), full and sudden discharge of CMOS battery, issues related to laptop LCD and finally - dead motherboard or CPU (built in motherboard). Still have to give it a try with external monitor and other AC adapter.
However, is it possible in this situation, that AC adapter just does not have enough energy in its tank to startup a laptop?
Any other suggestions, thoughts? Thanks in advance!
(This is a major disassembly project, though.)

The proper tool for repairing them is a BGA rework station, which is usually priced at the 5-digit range in our local currency (PH pesos).
