Dell Vostro 1014 unique power issue

Aug 13, 2018
I have dell vostro with windows 7 in it. Actually it's battery become dud and when I put charger in it only monitor screen lights up automatically , but no power to fan or motherboard. I tried dead reset by removing bios cell and pressing power button to release built in charge too, but no gain. Please help me out.
Some laptops won't work without a functioning battery.

However, it sounds like it isn't just a power issue. I would have it looked at as the motherboard may be the problem.
