Clevo 770DM died

So I foolishly left my laptop on all day unattended in a rather hot (84F/29C) room only to return to find the computer powered off. Now when I press the power button, the power led on the front of case turns green for a second, then back to orange and then quickly flashes green and back to orange. No fans, noises, back lights or anything else happens. I'm out of town at the moment but things I've tried so far with no success.

Tested output of power supply. 19.46V - Good
Removed battery, cmos battery and held power button down for 30+ secs.
Removed two sticks of ram on underside of case.
Left laptop unplugged, no cmos or battery for 6 hours.
Tried powering on with/without cmos battery.

Laptop doesnt smell like burnt electronics so I dont think I fried anything.
When I return home I'll remove the GPU, CPU and remaining ram, but was hoping someone might know what the led blinking sequence indicates as I was unable to find anything online.

 

Does the battery charge with the machine off and the power plugged in??

 

I'm honestly not sure if it charges. It's the original battery so it's well past it's expiration date and is only good for about 20 mins run time. I know when the machine was working it would sometimes take days for windows to say the battery was fully charged (the computer was on 24/7 pretty much) even when starting at like 76%. I'll leave it plugged in with battery and see if battery light ever turns green.

Forgot to add, I also removed last 2 sticks of ram, hdds and m2 drives and no change.

 

Yes

 

I'd take out the GPU and see if the machine responds at all.

 

Removed GPU...same blinking pattern on battery/ac with Nvram clear.

Then removed CPU...still no change to blinking pattern.

 

What about moving a single stick of ram about?

 

.

 

Chipset is cracked, yeesh. Board is dead then

Maybe a big surge hit it.

 

The GPU is probably ok. When a cap blows up and may or may not short layers under it together. That looks shallow to me. You can check it with a multimeter. The resistance between the 2 big solder pads next to it should be thousands of ohms. If the board is shorted it will be zero. If shorted, the short can be sanded out. I'm thinking this cap death happened a long time ago, but you didn't notice.

That PCH explosion is astounding. You can see all the glue around the die border is burned orange and peeling too. Something happened and the PCH heated to way over 300C.

 

Yeah good for the catastrophic failure reddit.
