the computer turn on fine, but when ever i move it it turns off and wont start again until i remove the battery and re-plug it, its really annoying what should i do to fix it
If the battery is good enough to power the laptop for at least a couple of minutes and disconnecting the power adapter doesn't turn off the laptop one can assume that the problem must be inside the system.
Does Windows properly shut down ? Probably not as you have to remove/re-plug the battery which means that there must be a loose connection.
You can try to reseating hard drive,cdrom drive,memory modules,keyboard,touchpad,screen etc....
Depending on your system it might be tricky for some parts and you can easily damage connectors if you are not familiar with hardware.
