my ASUS X540S sometimes cannot boot without connecting to the power and some times it can boot yet the battery says its 100%. Sometimes when i try to disconnect the power it shuts down and sometimes it stays just for a short time then goes off.

Laptop batteries do not last forever.
Likely, yours is failing.
Be careful about replacing it with a cheaper generic battery.
Sometimes the battery is very closely tied to the laptop for proper operation.
Best to buy a genuine replacement if you can.

I'd generally think it was the battery not putting up the amps, but it could also be a DC/DC power board. Just because it says 100% doesn't mean it's 100 per cent working. I've seen this behaviour in all kinds of devices.

I'd almost always get a new battery first, reason being, it starts fine plugged in with the superior current supplied by the aadapter.
