So Bios is ok. 5v and 3.3v rail ok..and you can turn on and off the laptop with all the main voltage present. the processor warm up when on. The only problem is the display is blank, no video on external monitor. visual inspection first top and botton of the mobo and then try to run the system with bare minimum. try to power the motherboard only and place an external monitor to isolate it from the rest. try to boot it. make sure to place the heatsink and fan as AMD is known to heat up fast. Maybe an attachment is malfunctioning.. the LVDS cable is shorting or maybe the battery or wifi card. a corroded connection burnt parts.. In my experience with this kind of problem the bios is my only suspect.. hehehehNever stop LEARNING because life never stops TEACHING!Comment

No display can be for N number of reasons and bios corruption is only one of them. No amount of disconnecting peripherals etc will yeild result as long as DRAMRST# is pulled low.Comment

Hello,
YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo
I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.
On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.
I also changed the screen because the PC fell and the screen was broken.
I changed the battery with a new and original battery.
I also had corrosion/oxidation on the... -

Power button works okay....power light goes on
Red "bottom" leds go on
Charging led works
Fans do not spin, capslock key does nothing, screen stays black
I would like to program the bios again, to rule out a corrupted bios.
However I run into a size error
The bios chip is a Winbond 25R256JVEN

Hi everyone,
I'm dealing with an intermittent problem and can't find a solution. Sometimes my notebook starts up and everything works fine. However, after I turn it off and try to turn it on again, the motherboard starts, but the screen stays black. It seems like the notebook freezes and a green LED with a light bulb icon stays on.
If anyone has the service manual or any suggestions on how to fix this issue, I would greatly appreciate it.
Thanks in advance!

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
Hello everyone !
My name is Chris, I am a 30 years old embedded software developer working in the automotive industry. I am really passionate about learning new skills and repairing/crafting stuff. I came around this forum last week with the goal of repairing my faulty gaming laptop, indeed, I was video editing on it when suddenly a black screen popped and never disappeared
I bought some stuff to try to repair it and learn as many things as possible about computer repairs but nothing worked so far. When the black screen appeared, my legion 5 pro was connected to my external monitor...
