Hello everyone,
Can someone help me with Fujitsu Siemens Celsius H730 bios mod - i need to completely disable nvidia quadro, remove it from bios if it's stored in.
Card has failed and after removing coils, laptop boots up but keeps boot looping with bsod ACPI BIOS ERROR.
I am not able to disasseble the laptop right now, so if someone can create new bios with this info:
Model h730
Serial nr DSDS030261
SAG: TOPH3CZ00
Thanks a lot

Fujitsu Celsius H730 bios mod request

Issue solved. I had to replace chip again because i managed to cook it.
TPS2456 is a direct replacement for FA3200. Once replaced, usb A port works again.... -
Damn, i just noticed... I dropped it in wrong way...

Well... Maybe i did something wrong, or fault is somewhere else but, it runs insanelly hot and now it does not say overvoltage but unknown usb descriptor.
I have installed the TPS2546 chip. I have few more so i'll try swapping them...Leave a comment:

Hey guys, I have same laptop with different issue: Only USB A port does not work and laptop shows overcharge/overvoltage on port and disables it. Otherwise laptop works well, charges, on charging USB C port on both sides, also both USB C work as normal. Only USB A does not work - port itself looks brand new - it is located on daughter board and connected via cable - when I disconnected the cable, error dissapeared. Any ideas?...Leave a comment:

Lenovo nm-a272 strange behavior
Hello friends,
I have lenovo g50 mobo nm-a272 , that is behaving weirdly.
After power on this happens:
[URL]https://youtube.com/shorts/tBUo6eokvHQ?si=6bTbbz8rvLA8HGgY[/URL]
Board had replaced superio chip, that was preprogrammed and tested in identical board, also bios was done the same way.
Board does have stable 5v and 3.3v, but nothing on cpu mosfet and logically nothing on ram mosfet.
Does the same thing with or without memory.
Any ideas?https://Hello friends,<br /> <br /> ...nm-a272 , that -
Re: Asus ROG N501JW - dead
Hi guys, i have two boards n501jw identical, both have it8585vg chip dead. After replacing, i get white light on power led and red light on keyboard but that's it. It stays black, and turn immediately on after powering off.
I have nice and healthy 5 and 3.3, aslo ~1.4v on RAM, but nothing on cpu and gpu coils and only about 2v on battery output. Also no charging light even after connecting the batt.
Any ideas? Dead bios?Leave a comment:

Re: Lenovo ideapad 520 power on issue
a year later, i still have laptop, but it developed another symptom. Fan runs at full speed all the time, once cpu get's over 50°C and no matter how hot or cold it runs, fan goes full blast all the time. It's fine while gaming but it's annoying when watching movies or working.
Board is almost identical to one in ideapad 330 , so if anyone had any idea what can be an issue, please let me know.Leave a comment:

Re: Lenovo ideapad 520 power on issue
yes, 10.3kOhm , anyway, i'll look up one on my spare boards.
I don't think it is the issue that's causing the board not to work when battery or cmos battery is connected in.
Also I have observed this:
