It could be a bad battery, or it could be a bad alternator, ground wire, dirty terminals, etc.
You need to test the components.
Charge the battery.
Then put a voltmeter across it.
It should read 12.5 volts about.
When you crank it, it should drop to about 10.
If it drops lower, the batter or starter is likely bad.
If it does not drop to 10, then the starter or terminals are bad,
If you stop cranking, the battery should come back up.
If it does not, it is bad.
Once started, then you should see over 13.5 when reved up.
If not, the alternator or terminals are bad.

the best way to check for a draw is to remove the neg cable from the battery charge if then place a test light between the battery and the cable if the light is on you have a draw then start to unplug connectors one at a time the first one i would test is the charging system plug first if the diode is bad it will drain the battery

Since you have replaced the battery and the ac adapter then there's a problem with your computer's motherboard. Get it serviced by a technician if he says that you need to replace the motherboard then you better buy a new laptop. Motherboards are expensive.
