Hi everyone,
I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.
Some history:
Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.
As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)
Now, with a new battery the system will start up and run off...

basically the board does not boot and have a rotating cpu/dram led on
all voltages present and everything is in place
nothing burnt nor ripped
except for a strange behaviour (ram rgb is on despite the board not switched on and only have 5vsb present only)
and 5vdual is always present and i don't know why
cpu&ram are fully functional so not doubt about that
any help will be accepted...Today, 09:19 AM -
I downloaded a BIOS file from Lenovo and once I extracted the actual BIOS from the executable, it is 16MB in size, but my IC(Winbond 25Q80DV) is only 8MB in capacity. I have read you can trim the BIOS file with a hex editor but I can't find any instructions on specifically what you will remove.04-27-2024, 10:55 AM

When plugged in (no battery installed), the battery light on the motherboard lights up and then turn off. When powering on, the same and light and the power button also light up in a white color but no output on the display. It stayed like that for a few seconds before shutting down. I also seem to ruined a connector that connects to the WLAN, 2 USB and audio board, the same board also have a melted 2062A IC. I will post pictures in the reply section05-11-2024, 04:40 AM

Hi
I have a Citronic AC-1USB.
When I run a turntable into it and then try to record it. The volume is too loud and distorting. In the red. Mainly 12” Singles. I haven’t tried a CD into it yet. I’m wondering if there is any way to bring the volume down inside the unit itself. Change a part or two. Put a small pot somewhere as there are no adjustments at all in there. I’m looking for the schematic but not found one yet.
Heres the circuit board inside.
Cheers

Good morning I have a problem with my [B]Samsung UE49MU6120KXZT (Version 01)[/B] TV with Motherboard[B] BN94-12644A[/B].
After disconnection from 220V the TV remains switched off with status led off. I need information on how to proceed with reprogramming the flash memory and the BIN file to reprogram it.
I have purchased this programmer on Ebay: [B]CH341A EEPROM PROGRAMMER FLASH BIOS 24 25 SERIES + CLIP TEST[/B]. I include photos of the motherboard. I am not very experienced but I would like to learn so the more detailed the information, the better it will be for me...Today, 04:55 AM -

I thinking to modify some ATX ver 1 supply, and wonder what if I connect 10k pot on 12v and center tap on brown wire? What range of 3.3v correction can to expect, or something will blow up if I close to rails, leave narrow 3.3v range?
It is KA7500B ic, but 3v3 sense is connected to TL431, I am not sure there is any connection between.Yesterday, 05:44 PM -
