Thinkpad W530 wont start

Hello,

 

In September 2016(a few days after end of warrenty Smiley Mad), my W530 suddenly refused to power on(turns off after 1/2s) or charge, so I took out the battery, disassembled it, and of course disconnected the CMOS battery, then after waiting several hours, I reassembled the computer and it worked for about 2 days without an issue, but then it failed again...

Since that I could always bring it back to life(till reboot or shutdown) by "just" waiting.

So my guess is that there is a faulty capacitor somewhere in the powermanagement part.

 

Any Ideas, where to search, or how to fix it(perhaps I am not the only one)?

 

p.s. I have an 100mhz oscilloscope, soldering iron etc.

They don't publish circuit diagrams, so it is nearly impossible to diagnose.  Unless it is something very simple, like a power switch, it is nearly impossible to diagnose.  Probably, you are looking at a motherboard replacement.

I think I will just take some hours testing with the probe, in search of a capacitor not discharing properly...

I have tried that, but was never successful.  It doesn't cost anything to try.  

 

Sometimes you can also find one that is shorted or burned.
