Problem with thinkpad x250
Problem with x250. On the original bios, the laptop flashes the LED 3 times when the power supply is plugged in. After pressing the switch, the laptop turns on for one second. On other bios the laptop starts up with no picture and gives 4 short beeps from the speakers, the keyboard lights up and when you press the spacebar the brightness of its backlight changes. Please help

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.... -
I want to fix a Lenovo Legion 5 15ACH6 laptop, the laptop turns on but the screen is black, GPU and CPU are cold.

Hello everyone,
I have a Lenovo IdeaPad 5 15ALC05 NM-D701. When I press the power button, the fan comes on, the power button flashes but the screen remains black. The device has a current consumption of 0.7A. I only have a BoardWiever for the device and no schematic. I have already tried to rewrite the BIOS, but the behavior is the same.
I have checked all voltages and everything fits:
PU1901 LV5028RPC - works
PL6202 -5.08V
PL6201 - 3.32V
PL300 - 0.77V
PL2101- 1.8V
PL1901 - 0.77V
PL1902 - 1.8V
PL1903 - 1.21V
PL5601 - 1.10V... -
Hi all,
I have a question about a Lenovo board (HS45Q - HS45S (NM-D891) - later I will update this with the exact Lenovo model number.
I'm not experienced at all, but I managed to get this laptop from someone that needed to get rid of it. He had a water bottle in his bag which started leaking.
The initial problem was that it didn't show anything on the display, but it did show stuff when I connected an external display.
I saw water damage around the lcd connector. After cleaning and checking all wires and lines, somehow during testing I managed to blow up IT8227....03-16-2025, 02:41 PM
