Lenovo Thinkcenter M91P Bios Request
I have this oldie i'm trying to revive. It turns on for about 2 minutes then the fans ramp up to max rpm and the pc shuts down so I think it's a corrupt bios that getting false positive for a thermal event.
Can someone assist or post a fresh bios?
Thanks in advance.

Kyocera M2535dn firmware bin
Hello friends.
I have a Kyocera M2535dn that was given to me to dispose of but before i do i thought i'd try to revive it.
It gives an error f246 which appears to be a general mainboard error and since the firmware chip is socketed i reckoned I might as well try the long hanging fruit first so to speak.
Anybody can help with firmware for this printer or maybe give me some clues where to look?
I've poked around the board looking for shorts or anything else obvious but didn't find anything as obvious as a dead short or blown component.... -

Re: Asus zenbook UX490u bios
I would like to share something with everyone that might end up here looking for bios help on the Asus UX490U laptop. I have only the CH341 programmer with the green board so not sure if this will apply to other programmers.
The 25Q64JVIQ bios chip on this laptop has a large ground/thermal pad underneath that is wider than the gap between the row of pin pads on my CH341 programmer so 100% sure the pins will short to ground and it made me get all FF readings from the chip or the software reported it's in protected mode. At first i thought...Last edited by odtech; 09-01-2023, 04:27 AM.Leave a comment:

Ok so it turns out the cpu was shorted or i shorted it injecting volts. Either way no more need from me but if someone can post for future troubleshooters...Leave a comment:

Re: Asus UX490U laptop blown (caps?) on power board.
My toolset isn't realy ready yet for doing this kind of trace, the board is small and densely populated. My main problem is I don't have a microscope yet and multimeter probes is too bulky. I'm going to sort both things soon.
The pad facing the cpu has 11.5Ohm on the 200 scale and the opposite pad has 1.5Ohm on the 200M scale.
Is the verdict still shorted cpu?...Last edited by odtech; 08-27-2023, 02:18 PM.Leave a comment:

Hello friends.
I'm looking for the board view of this Acer laptop. The components isn't marked on the board so board view preferred but can make do with schematic if need be.

Re: Asus UX490U laptop blown (caps?) on power board.
Hello friends.
I've have returned to this after taking a detour in trying to fix with a bios flash. My previous assumption was that it is posting but the display is dead but that was wrong.. The blown resistors was on the keyboard connector, not the display connector.
I beleive i know what the issue is now but it seems Asus doesn't like people repairing so I'm not finding any schematics and the markings on the component I beleive to be faulty doesn't bring up anything significant on google.

Re: Asus zenbook UX490u bios
I programmed this bios on the 25Q64JV chip and it made a difference but the laptop is still not coming on. Now when i connect the battery it immediately goes to max fan speed and the f2 button led comes on. The cpu does not get warm so the laptop didn't start.
Is there anything else i can try bios related or should i get back to troubleshooting hardware?...Leave a comment:

Re: Asus zenbook UX490u bios
Here it is.
I put the chip name in the file name in case it matters.
The 25Q80DV chip dumped suspiciously fast, assuming the 80 stands for flash size. The 64 chip dump took 2 to 3 times longer. Just mentioning it in case it's relevant.
Thanks for the assistance....Leave a comment:

Re: Asus zenbook UX490u bios
Hello.
I've finaly gotten around to doing this but i've got a small issue.
One of the bios chips isn't listed on Asprogrammer.
25Q80JVIQ
The two closest in the list is
25Q80BV
25Q80DV
Would it be OK to use either or should i get software with the JV chip support?
Any suggestion on software to try?Leave a comment:

Multi chip bios recovery
Hello friends.
Sorry if this has been asked before but i searched and didn't see the answer, maybe i used wrong search term.
I have a Asus UX490U that i suspect has a bad bios because the power rails are all present and no short circuits and it responds to the power button and it seems to charge the battery but it has nothing on the screen and it behaves oddly.
I want to flash the bios with a programmer but it has a couple of the same bios chips. How does one go about flashing?
Just a link to an post here...Leave a comment:

Re: Asus UX490U laptop blown (caps?) on power board.
Thanks for the willingness to help.
I decided to just try powering the laptop on after removing the blown caps on the IO board. I was slightly worried about letting the magic smoke out but nothing surprising happened besides the laptop powering on. The CPU heats up, caps lock turns on and off and when i press the power button a second time it switches off so it has finished posting and waiting I assume at the "no HDD" error since it has no HDD/SSD installed.

Re: Need bios hp fpw50 la-h323p rev: 1.0
I already check all the pins and swapped memory but will do so again just to be more certain. I'm chasing the bios now because some youtubers has had success with resolving 3 2 by re flashing the bios.
The reason I'm sort of convinced it is the bios is the fact that the laptop is basically brand new. It's a elderly man that bought it but didn't finish migrating to the laptop from his desktop then stored the laptop for a few months. When he fired it up it was dead as a door nail. So i'm thinking frozen bios but...Leave a comment:

Re: Need bios hp fpw50 la-h323p rev: 1.0
I tried by copying the offsets in post 53 from the original bios to a virgin bios but it didn't work. Caps lock still flashing 3 2.
In the ME cleaning guide they spoke about encryption keys stored in offset 2000 to 4000 that needed to be copied because my bios is apparently encrypted. Should i copy those too or not necessary?...Leave a comment:

Thanks friend.
I will try this tonight. I did start on this route but then i got stuck with locating my bios file so I went off on the cleaning the bios route instead which didn't work....Leave a comment:

Re: Asus UX490U laptop blown (caps?) on power board.
If you look at my original photo of the damage. Is the current sensor perhaps the small black component to the left of the damaged caps?
That area is directly next to the usb c charge port on the IO board but nothing is labelled so hard to ID.
As for measuring the coil resistance. I'm not sure why but i'm getting different results now. I'd have blamed my multimeter but not all the measurements is different and i've done nothing to the board besides setting it aside until now.
