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

Hey folks, I have this iPad Pro 12,9" 4Gen A2232 here with no charging issue. The main fault was a crossed pins / faulty USB charging port due a bad cable.
So I started to replace this parts:
- replaced usb-c port -> no result
- replaced battery -> no result
- replaced usb-c chip CD3217B12A -> no result
- replaced 343S00326 -> no result
- replaced 343S00327 -> no result
- replaced 343S00328 -> no result
I have no more ideas for this issue. There is no short on the whole board, and the iPad is working fine...Today, 05:37 AM -
Hi guys
In my spare time to upskill myself I buy joblots if stuff to fix , or attempt fixing and get some experience
I have a r460 that I wanted to fix and give to my nephew
As shown there is a burned ferrite bead, next to a high/ low side VRM pair on the back side of the card
I'm gonna try replacing these pair of VRMs. I wondered how hard they are to remove
I have a decent sequire solder iron and hot air, though may need to get a hot plate.. Seems these VRMs have big contact plates and could be welded
Also seemingly...Today, 07:54 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

Hello,
I have an HP 14-dq0055dx laptop here that came in for boot looping. It was previously taken to another shop and they tried flashing a BIOS firmware to the chip, so I cannot take an original dump. For a second or two, a message will come up on the screen that says:
This loop will go on for as long as you like. I let it run for about 12 hours and came in the following morning and it's still looping.

Hi,
I have a problem with windows activation. The laptop has the original version of windows 8 included by the manufacturer. The laptop worked on the original activated key for several years. Recently I wanted to try to see if I could still upgrade to windows 10 (it was a mistake). Of course, the time to upgrade to windows 10 has long since ended and my key was rejected. I came to terms with this and wanted to reinstall windows 8, I downloaded the system from the windows website, after starting the procedure it showed a window to enter the key, I entered and to my surprise now also...Today, 09:49 AM -
