I have compaq presario CQ62 laptop, recently my power adapter got damaged and i bought a new power adapter. My laptop had 0 percentage battery when i plugged in the new power chord, the laptop turned on but now it doesnt show charging icon in my battery icon although the charge percent increases. this made my laptop quite slow ( maybe because it thinks it is still on battery power only). One way i found was to uninstall Microsoft AC Adapter from device manager but it's only temporary, if i restart or scan for hardware changes same problem occurs. Please help how i can solve this problem
