HP 4740s shuts down after 30min - Clean ME

[Thermaltake]

Hi I got 4740s HP that I am trying to fix last 5 days but with no hope, so I said maybe someone here on forum will maybe know whats wrong with it. So laptop turns off after 30 minutes no matter if it's in full load or idle, or in windows or in bios.

What I try is

- different adapter
- flash bios to latest version
- change memory
- change memory module
- checked heatsink it's ok
- put new thermal paste on cpu and gpu
- disconnect bios battery for 1 hour
- disassembled it and look closely to chips and mosfets everything looks legit no burns or any suspicious things on motherboard or shorts when assembled.

I really don't know what else to do, I am starting to think something is maybe wrong with bios chip but I'm not sure if thats correct, can someone help me here, tnx.

Why dont`t you use search option
Post your old bios dump to fix you intel me region...What is the chipset and original cpu ?

I did search 4740s, but didn't find anything.

How to dump bios I never did that. I don't have old bios backup didn't do it, only this current latest that I flash. You think intel me region is wrong ?

Original and still in the socket CPU is i5-2450, and chipset is HM76.

Plus I can't remove this annoying admin. password that previous owner set, I know the password but It won't disappear even after clearing cmos. I tried to remove it in bios but when I enter setup bios admin. password section in bios I can see Administrator and I can only create guest account with new password but can't change the admin one because it's gray out.


EDIT:
I found now by searching a little further(didn't do that before posting, my bad) here that few other people have ME region problem, causing 30min shutdown, could be that I have the same problem then.

Hi
Did you comfirm fan works no lint balls hanging in side stopping the fan from running or not running fast enuff. If you tried a donor bios and never merged your original ME REGION then it's dirty or original ME REGION is corrupted in that case you need to rebuild it using the correct new chipset ME REGION and rebuild it with the intel fit tool for that chipset . Like i always say on intel model you just can't use somebody else bios AMD yes no ME REGION thats your problem if fan is clean and working 100% believe me i'm doing this over 30 years .

Fan is working no problem there. I am 99% sure that ME region is problem, I think it's been corrupted when I got it, I assume flashing new bios may fix the problem, but it didn't. Don't know if made mistake there, maybe I should left it on that version of bios that I had before flash ? Can I dump and flash bios from windows or I need to unsoldered bios chip and put it in reprogramator ?

Yep, i don't think that you can fix the ME problem with windows ...
You will need programmer, unsoldering, reprogram and soldering back
Well, maybe the god's here will say i'm wrong.

Hi I course it's fixable if you search my post I explain how it is done and what is needed for sure he will need a programmer even if I fix it for him.

Re: HP 4740s shuts down after 30min

This is why I keep trying to explain to everybody when they just ask for a bios dump even if it's in a new computer it only ment for that computer once it boots then its married to that computer so Im sure that's what wrong with yours so if you have a programmer upload original back up and I will rebuild you a new clean file .

Re: HP 4740s shuts down after 30min

hi friend,i think,its working fine within 30 min means bios is not a culprit.bios needed for startup process of the system only.after startup it will not interrupt.once i have solved a overheat and shutdown issue by installing proper graphics driver.u can also try this too..

It's not graphics driver, it's shutting down in bios too, doesn't have anything to do with graphics driver in bios because laptop did not load them yet when in bios.

That still require eeprom for flashing, and I don't have it. I will ask my college today if he can unsolder the bios chip and reprogram it and resolder it again. If someone can only edit me that ME Region and post bios here if it's not a problem, thanks.

@Thermaltake

I'm having the same issue with a Samsung also have a post here.

Also here are some infos regarding the ME stuff if you were interested.
--Flashrom site-- You'll see some links to pdfs and things near the top, also here is the neutralize me post/blog containing more info.

&

The programs they use for editing bios stuff usually starts with HEX editing, but I saw some other softwares that people use to overwrite the ME region stuff... Maybe things from here

Other than that I'm fairing new to BIOS stuff aswell

Anyways goodluck!

Post your old bios here to clear me region, if you dont know how to do it. You will need a bios programmer.
