    Often the problem on this mb with no display is DRAMRST# signal being either zero or pulled low to 0.4v-0.6v. So measure voltage on ram slot pin30 and report back. Your multimeter probe should be sharp and hand not shaky.However, if my observation is correct, your southbridge is faulty.
    Thanks for your help mcplslg123, but could you tell me where the PIN 30 is please.

        On The Ram slot. Look for pin marked as"2" and start counting from there. Pins are lcounted like 2-4-6-8 and so on. So it will be 15th pin if you count pin marked"2" from start.

            by m1ch43lzm
            Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
            Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

            Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)
            by HTR-Informatique
            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...

            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...

            HP Pavilion 15 bc400ns - Complete Black Screen - Only video on live usb
            by iZakre
            Hello everybody!

            To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.

            The thing is that I had installed TeamViewer and could log into the computer...
