Hp 800 G2 DM Schematic
Hello,
I need schematic for Hp 800 G2 DM 35w Tiny.
Schematic would be better but if someone can help identify a part it is also good. I'm looking for a circled part in the picture(U50?). The right front USB gets 5V from here. 54b18 is written on it. On another motherboard, xa5ed was written on it.... -

Re: Lenovo M93P Tiny restarts after Lenovo logo
I also found a bios on this forum and a vinafix site. I tried both but it only got worse. Power LED not lights, no sound, no display but fan always spin. I flashed back the original bios.Leave a comment:

Everything worked. Windows has been installed. When it was received by the customer, it no longer worked and Lenovo has been restarting ever since.Leave a comment:

Lenovo M93P Tiny restarts after Lenovo logo
Hello. I have several Lenovo M93P tiny that have the same problem. When turned on, the Lenovo logo appears and then restarts. It reappears, restarts again and it goes round and round to infinity. I can't enter the bios either.
I tried to replace both CPU and RAM but it didn't help.
What could be the problem? -
Gigabyte GA-P31-DS3L autopower on when turn on PSU
Hello. I'm still learning the motherboard repair, but now I'm stuck. I have Gigabyte GA-P31-DS3L motherboard. When I turn on PSU, all fan spin, but nothing else happens. I found a shorted MOSFET, removed it. I haven't been able to put a new one in place yet, but the motherboard is still doing the same.
I don't understand the connection either, since I removed the ITE chip, now the motherboard won't turn on, but PS_ON for some reason 7.5V and the voltage is slowly going down. If I short it, the power will turn on and the same voltage will appear on the power button. I thought the... -

HP 800 G1 USDT Bios problem
There is an HP 800 G1 USDT that has lost power during a BIOS update. Now it beeps 8 and doesn't work. I found a bios file for it. I flashed, the computer turns on but after a while the fan gets louder and then spins at 100%. I tried to copy the ME region of the old BIOS to the new one, I also tried to clean it but it didn't help. How could I solve this?

The T440 has 1 chip(16MB) if I remember correctly what the Lenovo [URL="https://www.badcaps.net/forum/showthread.php?t=87588"]autopatcher [/URL]can patch. I'm still a beginner, I only know this method.Re: Unlock Lenovo with "dual" chip.

Unlock Lenovo with "dual" chip.
Hello!
Sometimes I see a Lenovo laptop with two BIOS chips like the T430. One is 8MB and the other is 4MB. The autopatcher for this BIOS cannot create a patched file with which I can unlock the BIOS. I also tried to merge the two files, but then it doesn't work either.
T430 is just an example. , I come across several such laptops. How could these be unlocked? -

Re: Machine is not in committed state
If HP Unlocker does not clear the password from the BIOS dump, what is the solution?
I realized that if I delete the VSS store, I can enter the data with wndmifit and there will be no password. This helps in many cases, but here again the "Machine is not in committed state" error message may remain.Leave a comment:

Machine is not in committed state
Hello!
Many times I get an HP laptop that needs a new BIOS to flash. I usually find BIOS dump (with Clean ME) files on this forum. If I enter the data (serial, sku number, etc ..) with wndmifit and lock the mpm, the laptop is usually good.
But on some laptops (for example Folio 9470M - 6050a2514101-mb-a02) I get a red error message at boot time that says "Machine is not in committed state".
How can I solve this error?
