This has happened on three keyboards, so now I am assuming it is something in the machine but I can't track it down. Every time you plug in a logitech wireless keyboard it will immediately switch the "c" and the "v" permanent on these boards. There is no malicious software I can find, the board cannot be reset or put back. The very last one I tried was a MK 235 with the same end result. If you plug in a Microsoft wired comfort curve board, no problem at all. I have tried cleaning the system, deleting all boards from the device manager, updating the Logi software,checking MS...05-07-2024, 12:02 PM

I have Microwave BOSCH CFA634
It runs, but after 10 -15 seconds stops working.
Sometimes it shows error E1006.
I can't find this error explication.
Some people say it's communications error between main and display module.
Probably somebody has an experience with this issue?
Can you help me please?
Thank you an advance....Today, 05:17 PM -
The laptop I am working on is RAZER BLADE 15 , RZ09-0369, the motherboard is DA560 VER 4.0. The original fault was it powered up with keyboard rgb on and no video on screen/hdmi. I found corrosion on memory module that leaked onto the memory socket. I cleaned the memory socket and was able to boot normal with other memory socket with good memory. I really should have stopped at this point as everything was working except for the one bad memory slot.
I wanted to find out what was wrong with the other memory slot. I replaced a 330uf cap, a buck converter on back of board and when i...5 Photos05-15-2024, 06:37 PM -

by Arc717I am trying to downgrade my bios on my Alienware so I can undervolt & overclock my CPU, and overclock my ram. I need to get to bios 1.2.2 for this. Dell doesn't allow downgrades, and their bios file is an exe compiled in c++, so I can't decompile it easily. I am wondering if I can flash the bios manually using a usb flasher. I would like to know if this is possible, and if so, where the bios chip would be. I know flashers are pretty cheap and the bios chip is 8-pin. There are two of these chips only when I open the back panel of the laptop. I'm not sure if there are any on the other side of...Today, 03:34 PM

by orgamishoHello!
I am still learning on laptop repairs and I am currently working on the above mentioned device.
Currently the laptop is dead (no power on). The device takes 2-3 mA when 20v are injected onto the charging plug.
Main power rail is present (20v), but no other power rail is present, including the 3v and 5v. I noticed that when no power is connected the 3v and 5v coils have large (normal) resistence to ground, but when I plug the power, both are being shorted to ground.
I wonder is that an expected behavior or there is an outer protection activated.

by copeHi 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...05-13-2024, 09:40 AM -
