Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited... -
Hello everyone, I have an HP DV6 DAOLX6MB6F2 REV: F motherboard. The issue I'm facing is that sometimes the motherboard doesn't turn on. I've checked the voltages for the power on button panel, and they seem to be okay. Right now, it's working perfectly fine, so I can't pinpoint the exact problem. I have the HP DV6-DV7 Quanta LX6_7 (Liverpool) DAOLX6MB6F2 Rev 1A.pdf schematics, a multimeter, and a 5A power supply. If anyone could guide me on where to start checking first, I would greatly appreciate it. This is my first experience with this. Thank you.

To all the members here...
Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.
So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But... -
Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.
It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.
The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.
If I remove the...
