My asus netbook is plugged in and charging but the battery % does not increasing. It still on 0%. I left my netbook uncharged for 4 days. I replaced the battery about a year ago or less. Help me please. Already uninstall the microsoft acpi but still remain same.

It could be the charger or the battery. Even at a year old (especially if it is an aftermarket battery) it could easily need replacing.
