P870DM Not Working (Turns on and off instantly)

@Prema @Mr. Fox @Johnksss @Meaker@Sager

So long story short....my friend got a new motherboard for his P870DM and it was working fine with the stock style note BIOS. He tried flashing this BIOS: http://forum.notebookreview.com/thr...clevo-laptops-rtx-cards-now-supported.825558/ and his laptop was bricked...He tried flashing various BIOS using a programmer and it's still not working.

This is my old P870DM that I sold to my friend, it is in my hands right now.

Any ways....any suggestions on what I should do? Here's a video of what happens:

 

Well.. DID he put the new cpu or the old one in place!? The cpu might not be supported by the BIOS then that's why it doesnt POST. Try with the other cpu he had/has

 

The problem mainly will be the BIOS/EC, try the stock BIOS/EC in here https://repo.palkeo.com/clevo-mirror/P870DMG/ , make sure that the BIOS flashed successfully with the programmer. You need yo use only supported CPU's for this model like the 6700k.

 

Couple of notes...this laptop has collected dust for a few months. Everything tried was a few months ago.

We tried flashing my Prema BIOS..didn't work...and then my friend tried a newer bios (coffee lake from that thread) and it also didn't work.

When the first BIOS update was performed, it was successful. My friend did the GOP part and then it immediately turned off and started doing what you see. Ever since it's been doing that with all BIOS.

He thinks something shorted.

My friend has a i3-6100 and i5-6600K, no other CPUs. The Prema BIOS should have worked when flashed but didn't so might be something else going on.

 

If the ECU is corrupted then there is not much you can do.

 

Did you guys try a spi programmer.? Seems like a bad flash went on. Try a spi programmer in it and should be good to go

 

So basically he bent the bins on the original motherboard and bought a new one with the stock Clevo BIOS.

He wanted a new BIOS for the sake of having a new BIOS and flashed one from that thread listed. He said it was successful until he did the GOP part, where the laptop immediately shut off. Then started doing that.

We tried flashing my Prema Mod BIOS (keeping in mind all BIOS flashes were "successful") and it still did that.

A newer BIOS was released in that thread and he flashed it, same issue.

It collected dust for a few months and here we are now, it's in my hands and I want to try and fix it. If you'd like any other info I can try and ask my friend.

Here's what we used:

Program the GPU with the proper stock vBIOS, which is this one in case of a g-sync model 1080:

http://forum.notebookreview.com/index.php?posts/10915351

 

Just to be clear, this is a Clevo P870DM (OG model) with GTX 980 (desktop).

I just tried removing the GPU right now and turning it on and it does the exact same thing, I'm going to remove the motherboard from the chassis and see if it does same thing.

 

When you say "...he did the GOP part..." do I understand correctly that he flashed something to his 980?

If so please revert that back to stock vBIOS or PremaMod vBIOS via programmer.

 

Good question! For @Mangix He hasn't replied to me yet in text...

I just read that thread and the GOP was for 10 series so wonder if that's the issue. I never used programmer before, is this the chip I need to flash on the 980? I think I still have your old 980 mod bios somewhere.

Spoiler

Also....MB seem okay from these pics?

Spoiler

 

Yes, that's the chip. Clear it first, otherwise you have to manually build a full-sized image.

 

This option? Do I need to change the settings on the left?

Thank you

This is the vBIOS I have: CLEVO_GTX980_200W_OC_PM_v2 (189kb)

Spoiler

 

@Prema I got this after trying to flash the vBIOS lol

Spoiler

 

Wrong chip and size selected.
Does it not autodetect it?
Should be a GigaDevice 25Q20B for Maxwell.

 

Yeah clicking auto detect just shows those details you see on the left =/

"other
unknown
unknown" etc.

I tried connecting clip both ways and same thing. I can't even read what the chip is, do you know which one it should be?

 

Think it worked this time! Should I flash MB bios as well?

Now laptop doesn't shut off, power button stays lit but nothing on screen (no backlight). [although I have palm rest, kb, etc all disconnected.]

Spoiler

 

Yes, program the stock BIOS or Prema Mod back to the BIOS chip.

 

Okay I think I found a Prema Mod file for this MB but it might be old.

Which file should I use from this folder? And can I also flash EC?

lastly, which chip is correct for BIOS? Autodetect isn't working.

Thank you

Spoiler

 

The 8MB file. P870DM should use a 25Q64C.
Make sure to remove the CMOS battery for flashing.
You can not flash the main EC with your programmer as that is hosted within the 133 PIN ITE Controller itself.
Only EC2 has its own SOIC8 flash chip.

 

Okay, I seem to be getting this error when attempting to flash. Also when I read everything seems blank? (everything if FF)

 

They used different flash chips depending on board revision...just double check the label.
It maybe a 25B64C...

 

Looks like it's

AH1639
25B64CS1G
E69364

I tried GIGADEVICE GD25Q64
WINBOND W25Q64BV
EON EN25B64

all gave same error. Don't see one exactly same as that one

this is the correct chip right?

 

I've PM'd you an update for your programmer.
After recovery make sure to software flash everything once again with your Prema Mod package, otherwise his system will throttle due to the stock firmware.

Also tell your buddy not to flash random stuff from the net again, just because it sounds good. Newer isn't always better, especially when the firmware was designed for a totally different model.

 

Just curious, but did you do a USB flash first then SPI or SPI directly? If the latter, it may be an EC:BIOS conflict.

If your buddy wasn't looking to run a newer CPU that is incompatible with the older, stock BIOS, I don't see an upside to upgrading outside of wanting the newest (as you said )

And the CL Dsanke is a modified TM BIOS running on the DM. It works, but it isn't a proper DM Bios modified and tweaked. As of now, it appears it isn't 100% backwards compatible with the 980. After much trial and error
with a buddy this morning with the same laptop but running dual 980m's and stock BIOS swapping his 980m's into mine, it seems the Dsanke variant doesn't fully properly detect the 980 (seen as
'unknown' in the BIOS screen) and sees it as a single slot/GPU fan solution but dual 980m's ran fine.

If you had managed to get Dsanke up and running, you would have most likely faced a dormant secondary GPU fan which means, looking at the GPU heatsink for the 980,
your GPU will be somewhat cooled, but your ram, mosfets, etc... will heat up and your card will quit even under light load as GPU fan1 primarily focuses on the GPU core chip
and GPU fan 2 focuses on the supporting card structure primarily.

Hopefully @Prema gets you sorted out.

 

Thanks to @Prema we've made some progress. My original Prema Mod BIOS & vBIOS are now installed on the laptop.

Now I have the fans on blast with power light flashing orange...I was so close to getting it working too.

 

So its now EC panicking which would suggest either an issue on the system or with the ECU firmware.

 

@ssj92 's latest post today on the hwbot team looks promising in regards to the recovery of the system:

Spoiler

Tip: Bump the RAM and don't cover the render screen or the result will be invalidated by some normie.

 

nice! so its back to life @ssj92 ?

 

What's weird is...I flashed the Prema Mod through windows and it rebooted and was working fine. Then yesterday morning it started doing the EC panic.

Now again....not touching anything it boot up again.

Idk why it has this bipolar behavior.

It won't go above 3.9Ghz for some reason. No limits in TS, I increased power limits in BIOS and set multiplier to 4.1Ghz.

Sort of, besides that bipolar disorder of it working and not working it's kinda back to life lol.

Except no sound. Plugging in sound board does the exact behavior described in the first post video so I am guessing sound board is toast or idk. It's running all proper Prema P870DM mod files even EC1/2 so idk why else it's doing that.

 

The firmware he flashed has already killed a bunch of soundboards:

http://forum.notebookreview.com/thr...ounge-phoenix-4.809589/page-314#post-10920564

Most user just go silent and vanish when things go south...so you usually get them in your inbox asking for help rather than posting a failure in public like you did.

---------

Did you try to set the CPU multi in BIOS as well rather than TS.

 

@dsanke mod? Is that the mod you mean? Or another firmware?

 

Whatever they call those cross-flash firmware from those threads titled "Official".
I think they use annother user as proxy...

 

Oh. Mine is running good so far. No issues so far but I'll keep an eye on it

 

I have only heard from P8 user having this particular problem.

 

Cleaning up others mess Prema? Say it isn't so?

 

What's new?

 

The grumbling if you don't? No, that's not new either.

 

That's just how he is, he can't help it

 

People want to upgrade their machines and the ability to flash and suddenly have access to RTX cards and the entire line of Skylake based processors is very enticing.

Of course when things can (and do) go wrong, they panic and most don't know what to do. I've seen it in my gamer guild and their various Clevo's. I've upgraded / recovered
6 of them now and had to crack open every single one of them at their expense mailing them to me and back. Two more with failing GPUs and panicked owners who just
want to play their games which I completely understand.

I'm sure Prema has had more than his fair share of users message him, panicked, because their machines either won't start up or left in a weird state as ssj92's.

Dsanke is very unconventional, but when it works, it works well enough in a Frankenstein way. You have full CPU support up to the 9900k. Just about every BIOS option is unearthed
And after using XTU/TS to find my sweet spots, I no longer need them as I can set everything in the BIOS and go. RTX support for some machines is another plus.

The ability for the wide swath of Clevo owners from the original P870DM to the TM to have various upgrade capabilities to modernize their machines is a good thing, but the way the Dsanke
BIOS goes about it comes with numerous caveats and is not for the weak of heart.

 

Thank God people like @Prema and @dsanke exist. Else we would all be purchasing new machines right now.. Or we would be stuck in old hardware! But it's not for the faint of heart that's for sure. I had to get my ass to obsidian-pc store to get my machine flashed properly by someone who knows what they are doing. Thank god everything is working smooth as a baby's butt

 

It's not being weakened heart it's jumping in without preparations.

 

Keyboard lights also don't work, probably also got messed up in the previous BIOS.

The i5-6600K can't keep up with my 3920XM due to Hyper-threading but 4.6Ghz wasn't bad. I'll aim for 4.7Ghz next week lol

I set multi in BIOS and increased power limits in BIOS to 200W. Still runs at 3.9Ghz. I have to go back to my school apartment for the week but I will try more things next weekend.

Now that it's in my hands, i5-6600K + 980 needs some records on the bot.

I've been using @Prema mod since P570WM and have never flashed anything from anyone else. This goes to show the risks involved with these bios mods out in the public like my friend flashed onto this P870DM. The sound board is definitely gone because it does not boot up with it plugged in.

I actually thought my friend bought a 8700K or something, that's why he flashed it. I was surprised to know he still have the i3-6100 & i5-6600K.

 

It's why a lot of resellers like ourselves stopped publicly offering them and provide them on request.

 

Did you try Obsidian's KeyboardLED utility to see if that can light 'er up?

http://forum.notebookreview.com/thr...-by-obsidian-pc.801464/page-256#post-10793002

I've had Prema's handywork on a few systems that have passed my way back to Haswell and it has always been excellent. One of my 870DM's had Prema on it almost three years ago and it was great too.
Unfortunately, Prema does not have modernized solutions generally available for the entire range of 870/775 machines that allows modern CPUs and for some RTXs to be used for download. Dsanke's work isn't
as dialed in and polished as Prema's (understatement of the year) and it has more caveats, but at least it is available for the general masses to download freely at their discretion. Without it, I wouldn't be able to run a 8086k or see a 9900k throttle like a monster under load . DM and KM models have been EOL for some time now.

And yeah, a couple I fixed left me asking the owners, "Now WHY exactly did you flash this?"

 

I do have it installed but clicking the icon nothing happens.

 

@ssj92 you must install Fan Control first and run it. It should show you at least a CPU temp.
Click ''yes'' when prompt windows with dll install appears.

 

When you don't have access to awesome @Prema firmware mods and want to upgrade, you have no choice but to take a chance on a risky endeavor and hope for the best. Better to have a frankenmod that works (if it works) than do without the upgrade. If it works, that is always way better than forking over a ton of money for a new machine that doesn't offer anything compelling over the older machine that got upgraded at a fraction of the cost. Nobody except computer sellers benefit from that nonsense. One of the main points in owning a high end DTR with modular parts is being able to upgrade it. If you cannot upgrade removable parts due to silly firmware limitations, that really sucks. By the same token, an older machine that is slower and could benefit from upgrades, but still works, is a whole lot better than a bricked door stop, LOL.

In some cases a firmware "upgrade" (stock firmware, in particular,) can result in diminished performance. Been there, done that, and it sucks. Flashing firmware on a system that works right when you have no compelling reason to (i.e. just because it's a newer firmware version) isn't very smart.

 

Trust me. I did trust dsanke's modded BIOS after a load of time of reading and seeing other people doing it. Thank God my 8th gen cpu and his mod are running great and don't have any complains so far. But yes, having Prema's work would be a plus but where I bought it they didn't had any options for unlocked bios or anything like it. I wont be buying from them ever again (they aren't in this forum either so.. Doesn't matter.) I don't even advise my worst enemy to buy there so you see how much I love their work. Any further talking about this I will PM you Mr Fox and give you more details

 

Laptop is back in my friend's hands.

He mentioned the keyboard doesn't light up because the connector broke?
