Good morning Is it possible to modify and transform the source bios file downloaded on the official website? Attached is the Asus source file
otherwise I'm looking for the bios for this machine which is an I3 without a video card
I have also attached the original bios which I think has some problems, a notebook don't boot
Thanks...Last edited by Fabbrone; 06-20-2024, 10:58 AM.Leave a comment:

Dell precision 5520 It only starts with the battery disconnected and with the ac power not recognized message
[FONT=Aptos][FONT=inherit][COLOR=#202124]Already replaced adapter, battery and dock connector. If I only connect the adapter with the battery disconnected, it turns on with the message bios adapter not recognized. While if I connect both the battery and the adapter it doesn't turn on. When it turns on only with the adapter and I try to update the bios it tells me to connect the adapter! can being connected. If I connect the battery when it is turned on with the adapter it turns off. Do you have any ideas?[/COLOR][/FONT][/FONT]

Bios for Acer Aspire A515-45
Unfortunately I can no longer install Windows 10 or 11 but only Linux and I saw that it has an old bios version. I downloaded the bios from the official website but since the operating system is not installed I cannot update it. I therefore wanted to do it directly on the chip but the downloaded one has a different size as always.
I attach the bios downloaded from the site and the photo with the model
Thanks...Leave a comment:

Re: GM7MG7P No boot only backlight, need bios
I tried to update the bios but nothing changed when turned on the fans start then turn off after a while the backlight comes on. The heatsink gets hot and sometimes the fans spin but always just the backlight. It's probably the graphics chipLeave a comment:

Re: Dell precision 7250
I have to correct the model which is actually a precision 7520 not 7250. I checked the voltages on the connector of the inserted battery and inserted adapter . On all pins there are 0 Volts except the 3 pin from the left there are 4.7V
A jack connector is ok
A board is CAPOO LA-E311P Rev 1.0...Last edited by Fabbrone; 10-26-2021, 09:29 AM.Leave a comment:

Re: Dell precision 7250
The test I did with the soldered mosfets by putting the black probe on the Source there are 0.5Mohm even by inverting the pins. Black probe on the gate and red probe on source and drain 2.5Mohm inverting me from open circuit.
However, I believe that if these two mosfets were faulty the notebook would hardly turn on.
Excuse my language, I repeat the problem of the laptop if I connect it to the adapter it turns on and works correctly but does not charge the battery. If the battery I load it with another laptop ok and I put it on this faulty one...Leave a comment:

Re: Dell precision 7250
a mosfet is EMZB08P03V with a multimeter negative on Drain and positive on Source is open . On reverse a multimeter bip. Positive on gate and negative on Drain or Source is open. Reverse ther is a resistanceLeave a comment:
