flex 3 not powering on

Hi everybody,

                         I was working on one flex 3 doing a diagnostic test with WD diag when computer shutdown.

When I push power button battery led flash 3 times but no power. 

First I was thinking cpu overheat since the first problem of this notebook was is slow speed

So I clean old thermal paste and put new one

Try to boot battery led flash 3 times but no power

Remove battery and cmos battery , clear cmos, plug everything back then I start the notebook power light and keyboard light turn on 2-3 second and then turn off. 

After that just 3 battery led blinking

Need to remove cmos battery and clear cmos to got power light turn on for 2-3 second.

I also reseat memory just to be sure

I have no clue what I need to try can you help me please?
