Dell Laptop M1050 Not powering on

Also try removing the battery and doing a static discharge, it often works.
Steps:
1:Turn off computer
2:Remove battery safely
3:Remove power cord
4:Hold down the power button and count to 45 (45 Steamboats [1 steamboat, 2 steamboat, ect])
5:Plug in Power cord ONLY Not the battery.
6:Turn on computer, Computer will take longer to boot up as it has no electric current going through it at all.
7:When computer is fully booted up turn off and plug in the battery and turn on again. (If it doesnt turn on with the battery inside, the battery is dead)
8: If it doesnt turn on at all, i suggest Googling this, '<Model> <Brand> Wont turn on and is beeping <Enter amount if in sequence>' [Example: Asus P4C800 wont turn on and is beeping 7 times]

How to find the model: www.asus.com/ca-en/support/article/565/ (Different brands may have different ways)

Determining the exact cause is not going to really help. There is hardware damage either way, as is indicated by the beep code mentioned earlier in the thread.
