Hi, i have an HP AC power adapter with (on the label) 19.5V DC. checked it with a voltmeter, it was 19.78V DC. whenever i connect it to my laptop, it doesn't charge the battery or wont power up with battery removed and adapter plugged in.
Checked a second same adapter (friend's). Same rating on the label but output of 19.85V DC. and it works fine with my machine.
is there some workaround or do i buy a new adapter?
