Hi,
as noobie to this please excuse my lack of experience.
I am trying to remove a BIOS password from this machine:
[B]HP ProDesk 400 G6 Mini [/B]
but so far I still have no success.
I bought [B]CH341 programmer[/B] and decided to give it a try.
The programmer came with [B]8 pin [/B]cables and connectors or whatever everything else is called so I had to buy a new [B]16 pin cable[/B] because the chip which I think is the BIOS is with [B]16 pins[/B]..

Hi! I was given this TV. It would turn on fine but then after a while the BL would shut off while rest of functions would stay working. I assume this 99% means a shortcut in the BL so the PS detects the overcurrent and shuts off the BL pwr.
I managed to keep it up for the time enough to enter into settings and turn down the backlight to 50% which seemed to help. I was able to watch it for some hours several days
But the other day, I went to try it and the BL didn't even start at boot up. I want to repair it but: This is a spare TV that I want to keep at a house that I seldom...06-03-2024, 12:58 PM -

I found my old Xbox 360 in storage and opened it up to see if there was anything that broke since it was built in 2006 (launch era Xenon revision, never red ringed, never been serviced) and didn't want to find out by releasing magic smoke. Upon moving the dust bunnies out of the way I was greeted by a bunch of capacitors with crud coming out of the top; it doesn't seem to have leaked onto the board so at least I have that going for me.
I'm posting here because I want to try to source replacement caps myself from Mouser or Digikey instead of braving eBay or waiting for places to have...06-07-2024, 05:10 PM

Hello guys, can someone help me with an eMMC dump for a Sony KDL55W-955B TV, I tried to read the original memory with the RT809H but it shows me that it only has 1888MB even though it should have around 3.8GB. On a new memory it shows me 3776MB. From what I found on the Sony page, the following models could also be compatible:
KDL-65W955B, KDL-55W955B, KDL-60W855B, KDL-50W805B, KDL-42W705B, KDL-32W705B, KDL-48W605B, KDL-40W605B, KDL-60W605B, KDL-55W805B, KDL-42W805B, KDL-48W585B, KDL-32W706B, KDL-42W706B, KDL-42W815B, KDL-42W817B, KDL-50W815B, KDL-55W815B, KDL-42W828B, KDL-42W829B,...06-08-2024, 04:13 PM -
I am still working on an Lenovo e14 AMD notebook with some problems. The laptop booted normally but had a ton of problems with the soldered ddr4 memory. I tried deactivating the memory via bios, but that didn't work.
As i have a matching donor here, I decided to change the module i suspect to be faulty and exchange it with one of the donors.
Did so, but now the laptop won't boot anymore.
Anyone here who already did that and can comfirn, that exchangeing one module alone would work? Or do I need to exchange all 4 of them to make it work?Yesterday, 02:42 AM -
Hey guys! I've recently found out this amazing forum where people talk and discuss about electronics repairs and i'm actually amazed with everything that here's have to offer.
Oh well, i came here looking for a simple bios file in order to get my main laptop working again, but after a while trying to figure out what the hell was going on, i'm quite concerned that it would be worse than i tought. I was fooling around with Mr. Smokeless's UMAF BIOS mod, looking for a way to enable CSM compatibility and legacy boot on my device.
