Very good to all, I hope you are all well,
I need a little help about a Packard Bell New70 La-5891p laptop motherboard

The question is that the laptop with the battery and the charger at the same time turns off in a few seconds, on the windows screen I get the typical image of the battery connected and without charging and soon after the laptop turns off

The client tells me that the battery charges and works well in another laptop with the same...

Hello and thanks to everyone
I have a Hantek 6022BE brand oscilloscope which due to my error causes a short in a board at a network voltage of 220V, and as expected the oscilloscope does not work

He replaced a protection zener diode and a fuse resistor at the input that were short but the oscilloscope still does not work for me so I keep investigating

Injection 5V (With regulated source) at the input and gives me a consumption of 300 mAh and two integrated with 74HC4051 license plate (multiplexer and demultiplexer) are heated, each of these integrated corresponds...

Re: Shorted motherboard? ASUS K53SD

Thanks Caspian for your interest in my problem and hello everyone

I have cleaned the socket of the processor and possibly it would be dirty, but now I HAVE vcore with the processor on, the processor heats up as normal and the LEDs are already fixed without flickering as they did before
But the fan doesn't work
When I connect the 19V (with regulated source) it gives me 150mAh without giving the power on, that is to say that the power on does nothing, the 3V reaches all the bios memory and all the voltages OK
Something...

Hello again and I hope you are all well

A board that I rescue and that I am now taking up has a problem which does one thing with a board and another without a board, I explain

Board consumption with 200mA processor (board only) only the LEDs turn on and the board does nothing

No processor in place; board that has all its voltages (3, 5, 1.2 V Etc) the LEDs (battery, wifi, etc) flashing every 7 seconds and correct power on voltage


With processor in place; it has all its voltages except vcore, in which I inject 1V and it gives...

Re: Bios for GIGABYTE GA-M55PLUS-S3G

Excuse me, but I don't know very well what is coming to you.
What does it mean, thanks

Hello, I need the GIGABYTE GA-M55PLUS-S3G - REV 1.2 motherboard bios, since when I download it from the manufacturer's page I only get three files and none of them with the bin specification

I want to burn it to a bios chip to rule out a bios problem
I leave images of the bios files of the manufacturer's page that do not work...
