I wanted to use a laptop again after a long period of inactivity (half a year). But now I have to realize that there's no picture. The fan twitches when switched on and then goes out. However, after a few minutes the fan switches on again. (It does not run at full throttle) External monitor connected, does not work either. BIOS pulled battery did not help and RAM works. The PC doesn't beep. He just doesn't do anything. I disassembled it to change the BIOS battery.
Looks like the NB has too little power.
Did you use the correct power adapter? Maybe it's also defective - use another suitable one…
I used the appropriate power supply and also measured it with a multimeter.
It happened to me recently that one power supply provided power, but only for a relatively short time - it worked with another.
If you can take out the battery, I would try it without…
The battery is outside because it was defective anyway. What seems strange to me that the CPU gets warm normally. As if the computer was doing something but it is simply not displayed.
