      sounds like a mainboard issue.

          Yes definitely a main board looks like main chip has failure due to bad bga soldering.

              Hit it with a hairdryer for a few minutes, then see if it comes on for a bit.

                          No bad soldering in this case!! Use immagination.. bad lamps means overvoltage , then also overvoltage to the main board! check the standby software memory first.. is there a spi flash? rewrite it..

                              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.

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...

                              MSI GF63 THIN 11UCX (MS-16R6) LAPTOP WON'T TURN ON AFTER RESTARTING
                              by RdeveLabs
                              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...

                              Acer Aspire 4520 won't turn on after reboot
                              by robante15
                              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...

                              Dell latitude e7470 not turn on .power buton on off and Run Power problem
                              by masoksian
                              Hi everyone,

                              I am dealing with the problem of turning on and off my Dell e7470 notebook.

                              The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.

                              The system does not turn on, there is no post.

                              I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
                              The problem continues in the same way.
                              I tried to turn on the Fn key, nothing came to the screen....
