Hey gurus
I need help clearing the bios from a Dell G15 5515 (Ryzen Edition), la-k454p version 1, ST=1W7ZTN3, EX number 4125128655. I've done the Dell shuck-n-jive & couldn't find the S# to save me, so, no clue. There's a DP/N 8CK0N A00. And, lastly Reg Type No. P105F004. Past that I'm clueless.
I'd sure appreciate the help getting this thing unlocked & this client out of my hair.
Thanks bunches you guys....

by norbiszokeHello,
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.

by reassorHi.
I got dead one.
3VALW is just pulsing then goes down. i removed the jumper PJ402 and it suddenly stays up but PG pin on that IC is around 0.5v and droping.
There is no obvious shorts. Wierd thing is that on the other side of the PJ402 i have 1.4V from somwhere ...
Injecting 3.3v there draws 300mA and nothing is heating up.
the ic is SY8386BRHC_QFN16 (kinda uncommon here - so i do not have a spare to test it)
any ideas to check before i order a few of these?Today, 01:47 PM -

Hi, I need help to identify the component with marking "9003 KAUCHB".
A bit of background...
I have an induction hotplate UNOLD Elegance Typ no. 58105 (with board CHK-A1.42S) which has a blown resistor.
I have also located the problem in the SOT23-6 component with the marking "9003 KAUCHB"; the pin 5 was disconnected from the IGBT emitter (ground) due to the high temperature and this caused the IGBT to be permanently ON.
I replaced the resistor and resoldered pin 5 of the SOT23-6 component to the IGBT, the hotplate worked for about a month and...1 PhotoToday, 12:55 PM -
by AdrenalinTLHi,
Very new to this. So pretty basic / silly question. Can this be the cause of a totally dead mobo? And, is it repairable if I bridge tracks etc?
Thanks1 PhotoToday, 11:36 AM -
by DoOm86TV philips 55'' no backlight (image ok).
I tested the backlight with my led tester from the unplugged connector cable and it lights up. I had voltages at the motherboard connector, but anyway I order a new psu. Same problem, same voltages. Disassembled the TV and checked every strip with my led tester, they all light up, same voltage for every pair of strip (they go two by two).
What am I missing?
And something else I don't understand. I checked and I have 3v Leds, 10 per strips. Why every pair of strip (so 20 Led) take about 32v when powered up with my led tester 🤔2 PhotosYesterday, 03:47 PM -
by StormCrowHi folks
Got a 14-eb0013na here that won't boot - have attached original BIOS dump
Serial number: 5CD203HPS8
I wonder if anyone could sort this for me so I can re-flash?
Also interesting in learning how to do it myself, is it the ME region that needs clearing on the HP laptops?
Many thanks...-

by trepachkaSee attached image. It says "X322" on it. This is a follow-up to my previous posted topic. The issue is upon lid closing, the screen turns off. When lid is opened, the screen remains dark.
This component is positioned right on the edge of the motherboard and has like a cradle made inside the case. I am assuming this component is used as a lid close sensor.
Please, help me identify it. Thank you....Yesterday, 03:26 PM
