Dell Inspiron 1501, died and will not restart

replace your memories and start again

The lcd back light hs gone, there are many repair sites for dell, so do a google search for spares and repairs type the model into the search bar and it should bring up the parts you need and how much they will be, if you buy a back light the instructions on how to replace them normally come with it.
hope this helps.

Go to Control Panel/Power Options and check the settings. It's probably set to shut off after a period of time.

try getting a new battery- the cmos losses it settings when battery is dying

hello
This could be anything from the screen is dying or the inverter (electronic board that powers the screen' back light).

If you press slightly at the top of the screen, see if the lines will disappear or not, if it does then come back again; you might need to change your lcd.
hope it helped

Does it power on at all? Do you see anything on screen (DELL/BIOS for example)? Is it in a docking station? Also make sure the power is attached.

Two things that you can check that cause this are the battery and the memory. Remove the battery and start on the power supply only. Then remove the memory and try each chip, one at a time in each slot. These are the two main causes of a no start with Dell machines. If it's not one of these, then the problem is going to be with a motherboard component, and you will need to take it in for a professional diagnostics in order to track down the exact problem area.

Sounds like your audio plug in is damaged
