Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.
My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).
Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....

Hi all,
Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.
Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...Yesterday, 03:15 PM -
Hello everyone,
I'm trying to fix a small LG TV with wierd issue.
So I check that the display is OK by fashing a lamp at the screen. LCD is okay OSD is showing up.
Now since the BL is dark, I disconneted the BL from the mainboard and I injected voltage to it with my blacklight tester.
The BL turns on, the tester shows around 80V. So the led strips are okay it seems.
Now I started to suspect the BL driver IC which is a MP3378.
I have a donor board (dead cpu) with the same IC, so I swapped the driver IC but it did not solve the issue.

Not sure if this is the correct place. I need to identify This IC id anyone could help please.

Hi All,
Laptop: ASUS F15 TUF Dash FX517ZC-HN114W
Context: When I was out the house my partner hard shutdown laptop while BIOS was updating, so my son has no working laptop now. Also as a result I know the BIOS on the chip is messed up so I can’t extract it using the ch341a and use it to perform the method explained on site to modify an update downloaded from the ASUS website to get the BIN to flash.
If anyone can help with a BIOS BIN/ROM file for this laptop, I would be forever in your debt! Thanks if you can help!

I am trying to get a set of Creative T40 computer speakers to work again of which I believe the problem is bad caps (470uF @ 35V). So I get a generic set off Aliexpress. The brands are meaningless, but if anyone cares it's a "Chongx"
When they arrive, to my surprise it's much smaller than the originals. These are 8mm x 15mm whereas the OE is 10mm x 20mm. Unfortunately my meter does not test capacitance but I'm guessing there's no way this meets spec at 80% the size.
Thoughts? Is it still worthwhile or safe to try and install these to see if...Today, 04:31 PM

Hi guys.
I own Alienware 17 r3 6820HK GTX 980M.
I purchased it recently tried some gaming (Rise of the Tomb Raider, Serious Sam) and after 10-15.min games freeze, but I could hear audio from game.
Now I am not yet at home, but when it happens I do get separate window error message and will post it later.
Then again there are moments when I could play for like an hour and no errors.
From my experience reading about this issue, this means my GPU is dying, correct?
I installed most recent nVidia drivers.

Hello,
We have this set here in our shop that is not ginving sign of life besides red light that is blinking one time after pressing the button and nothing more... After detaching the mainboard from the PSU (this set has separate board thank god?! or not...) the backlight comes on. After reattaching nothing besides red light.... Can anyone from the forum help me here? Thank you in advance. Here's a link with images of the mainboard and the memory IC's that are on it.

I have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on.
