Toshiba L50B wrong GPU temperature+IntelManagement error

[Dannyx]

Good day folks. I've got one sick little laptop here today: it's a Toshiba L50B, which is a POS to begin with (broken hinges, missing covers, it's a mess), but it also displays some complex symptoms: on top of random shutdowns, speedfan reports a totally ludicrous GPU temperature of 150-something degrees and I also get a "status_device_power_failure" message in device manager undel Intel Management Interface, so I think all these might be related. Is this a failed hardware components that's causing this ? I could ignore the temperature reading if the laptop was fully functional otherwise, but it's not...

The driver fails to install with an error message that basically says it cannot connect to something - can't quite remember how it went.

The motherboard is a DABLIDMB8E0 Rev e if we can even get that far with the repairs Cheers and thanks for any support.

Post your bios backup. Might be the ME are of the bios is corrupt .

EDIT: First, uninstall the management engine drivers,reboot and install the latest driver,that might fix it,if not, post your bios backup.

Re: Toshiba L50B wrong GPU temperature+IntelManagement error

So I'd need to remove the BIOS chip, read it and post the resulting BIN ?

EDIT: The driver you provided did install successfully, but the error is still there in dev manager.

Re: Toshiba L50B wrong GPU temperature+IntelManagement error

I agree with smdflea. All symptoms indicates towards me region corruption in bios.

Re: Toshiba L50B wrong GPU temperature+IntelManagement error

Yes,you can backup the bios that way with a programmer.If you have a sop8 clip you don`t need to desolder it.

You can also try backing it up via software,but if the flash descriptor area of the bios is locked (probably)you won`t get a full backup only partial.Theres some software called bios backup toolkit,on these forums if you search for it, thats the easiest way or you can use intels Flash Programming Tool ,from the command line.

Naah...just bust out the clip and do it that way. I shall post my results tmmoz hopefully...I HATE taking this thing apart, all broken and smashed, falling into a million pieces.

Did I mention it randomly shuts down ? I did Could it be related to what I'm trying to fix ?

I agree with smdflea. All symptoms indicates towards me region corruption in bios.

Yes,its related to the shutdown,usually at around 30 seconds.

Re: Toshiba L50B wrong GPU temperature+IntelManagement error

It's not that abrupt - in my case it takes like 30-60 *minutes* for it to die, but it DOES happen nonetheless...

Re: Toshiba L50B wrong GPU temperature+IntelManagement error

30 minutes is ME region. If it lasts longer, that may be something else (overheating). But still, ME region is a good candidate.

Re: Toshiba L50B wrong GPU temperature+IntelManagement error

Already replaced the thermal grease and dusted the fan, so it's definitely not overheating, though it could be that something else is failing when it starts getting warm. Still, it happens at idle temperatures too...I shall dig further tomorrow.

Re: Toshiba L50B wrong GPU temperature+IntelManagement error

Here's what came off of that BIOS chip. I actually had to remove it to read it, because with it still on the board the power LED on the programmer would go dim and the software would tell me it's not connected, so I think it's trying to power something on the board as well....anyway. I'm not sure what it's supposed to look like, but here you go. The chip showed up as "unknown" and the software wasn't able to determine what chip it actually is, so I hope it's OK.

EDIT: I noticed there's also a 24C08 chip on there, so I read that as well. I can see somewhere among the Hex code the model PSKTCE on there.

Hi
it is fixed Bios

Re: Toshiba L50B wrong GPU temperature+IntelManagement error

Is that a file you already had, or you edited mine ? If so, I'd like to know what you did to it.

I also discovered the laptop doesn't turn on with a different IC on there: not wanting to mess around with the original IC, I though I'd try a different one for testing, so I programmed a different 25Q64 with what I obtained from the original IC and the laptop just stood there with its caps lock light on and that's it......is there a difference between a 25Q64 and a 25B64 ? The B version is the original. It could be that the original bin wasn't ripped correctly in the first place, hence why it refuses to run with other ICs....

EDIT: same thing with the BIN you sent: on a different chip, it just stays there....I'll try it with the original, see if it changes anything. I'm a bit reluctant TBH

Re: Toshiba L50B wrong GPU temperature+IntelManagement error

Update: tried out the BIOS mielta sent on the original chip, it works (so the IC is important after all), but I still get two 511C readings for the GPU temperature and the error in dev manager is still there...don't know what to make of this...

Re: Toshiba L50B wrong GPU temperature+IntelManagement error

Great, i`m glad its half fixed. And i do know its 30 *minutes* and not seconds as i said at post #7

Re: Toshiba L50B wrong GPU temperature+IntelManagement error

No, it's not fixed, that's just it The chip programmed fine, but I'm still having the same issue Sorry...I think there's something dead on the motherboard...

I don't know why people are still using Speedfan. It is horribly outdated. Try HWINFO for a change.
