Hi everyone 😀,
I'm here today to ask for help with repairing the motherboard of a [B]Lenovo Legion Y540 17IRH[/B].
To give you some context, I'm passionate about computer repair so much so that I've invested in a lot of tools and started practicing on dead and old hardware. I've been learning how to solder and desolder components, mostly focusing on phone repairs.
Recently, I bought a broken Lenovo Legion Y540 17IRH for just €150, and there are two main reasons why I made this purchase:[LIST=1][*][B]I already own the exact same model[/B], but its plastic...06-10-2025, 04:24 PM -

Hello. Need a fresh look. MacBook shows no signs of life.
When connected to USB-C with the battery connected, the consumption is 20V/0.220A and PPBUSG3H=11V.
If you disconnect the battery, the consumption will be 5V/0.220A and PPBUSG3H=12.3V
PP3V3_G3H=3.3V
PP5V_G3S=0V
PP1V8_SLPS2R =1.8v =0v=1.8v =... cyclically

Maybe now he decide to post... This forum is become so unreliable... I hope you see the attachment... So, I have newer cheap 830 dmm, and I am not happy with beeping mode.

But, I dont know principle of reading such complex connector, so please if you can draving with red lines path that exist in beep mode... it will help me a lot....Yesterday, 07:04 AM

I am trying to repair my Samsung Chromebook Pro. There is no boot. Upon turning on, the screen is blank and there is no backlight. Power LED is blue. I tried refresh with power and esc refresh with power with no avail.
When I measure the 1.2V rail, it is pulsing. It will jump from 0 to 1.2V then 0 again. I replaced the 2 MOSFET and even power management IC and it is the same. Resistance from midpoint between mosfet to ground is 0.5 kOhm but it will show 250 Ohm first before jumping to 0.5 kOhm. So it feels like it was charging up some capacitor. Since MOSFET and IC was replaced, I...06-11-2025, 08:11 AM
