P870DM-G won't post. Turns on, no display, fans spin, then laptop powers off.

Hi,

 

A few years back my Clevo P870DM-G simply stopped working. No apparent reason. After doing all the usual troubleshooting and tricks, I simply gave up, stored it away and built a new SFF PC.

 

Anyway, I decided to try to resurrect this thing from the dead one last time.

 

++Same behavior as from the last time I tried it. Power brick has green light when plugged in. Plugging into laptop lights up the charger LEDs in the front. They are both orange at first but after a while it charges and the left battery LED turns green. I press power button, power button light turns on with the cool strobing effect, the front right LED turns green, keyboard lights up, no screen or post or any other activity beyond the lights for about 20 seconds or so, then the fans turn on full blast and they stay on for about 35 seconds straight and then the whole laptop powers itself off. And that's where's it's been the past several years.

 

I completely dissembled the laptop and reassembled. Tried one RAM stick, different slots, swapped out the 6700K wit ha different 6700K, swapped the 980GTX with another 980GTX, reset CMOS, swapped keyboard, etc.... nothing changed the above mentioned behavior.

 

Any suggestions? Would a BIOS rom flasher be something I should try? That is the one thing I never tried. I'm not familiar with them, so not sure if this is something that would require modding of some sort?

 

I do have two BIOS zip files for the laptop, a version 02 (original from the Prostar reseller at the time, emailed to me by one of their CS reps) and a version 08 (later version I found on the old Notebook Review website someone sent me), but I'm not sure what file inside it would be used with a flasher. Or even if that's worth trying. There's a bunch of files in each zip folder and they're meant to be launched from the OS itself. I posted a pic of both bios file folders if anyone can make heads or tails of them. I also still have all the driver files, if I can actually get this thing running again.

 

Anyway, any suggestions? It's been a few years but I have all the parts for it still intact and everything looks in pristine condition. Should I give a flasher a try? This isn't an emergency BTW - I'm just saddened such an awesome looking laptop doesn't work and I want to see if I can save it.

 

Thanks.

Buy a cheap ch341a bios flasher and try to reflash the bios. The file to flash with the programmer will be P870DMG.02

Ok, I'll give it a shot and report back.

 

Would something like THIS work? I never used on of these before.

Awesome. Cheap enough for me to try it out at least. The guy in the review video used software called NeoProgrammer 2.2.0.10 to operate the flasher. I'm guessing that would work? Is that easy to get? Not sure what the official site is for it. Or is there better software to use it to try to flash my Clevo board with it? Thanks again.

Got it. Now I'm just waiting for the programmer to be delivered this weekend.

 

BTW - I posted some questions in another thread, not sure if you can answer any for me?

 

1. Do I need to rename the BIOS file in any way to get them to work? Example, with the P870DMG.02 file, should I change the .02 to .ROM or .BIN? Also, do I need to convert them to different file types, or is just simply renaming the extensions good enough? Or will the programmer be able to use it as-is with no changes?

 

2. BTW - The BIOS chip I have is a Gigadevice BH1540 / 25B64CSIG - labeled on the top of it. That'll work with the programmer & NeoProg right?

 

3. Do I need to plug anything back into the motherboard before trying to flash it? Right now, I have the motherboard unplugged and removed from the case and all the hardware removed (SSDs, RAM, WIFI/BT chip, keyboard, laptop battery pack, CMOS BATTERY, GPU, etc...). Only thing still plugged in is the CPU.

 

I'm trying to get everything set up ahead of time to make sure I do it correctly. Thanks!
