so as the title says my 3 years old dell n4050 laptop doesn't start up. I checked some sites for troubleshooting and followed some of the steps like removing the battery and the power adapter and pressing on the power button for a minute then connect it to the power adapter once I did that the laptop started to boot but then made a beep and shut down again.
My power adapter is working fine because I tried it on a different dell laptop and worked just fine. What should I do now?
There might still be a chance that you might still revive your laptop. Remove the battery again and the AC adapter first then take all the RAM off from it as well. Press and hold the power button for 20 secs then put it all back together then turn it back on.
