DELL Alert! The AC power adapter wattage and type cannot be determined
I got a new surprise from DELL, again I had no clue what was the problem. The laptop had extremely slow performance (open/close files, internet connection, open/close programs, bootup and shutdown), keystrokes had a big delay and also sounds could not be played. What I did was: - update drivers - scan for malware - Factory reset - Dell diagnostic tool - Dell hardware diagnostic the one accessible from one time boot menu - etc and nothing worked for me!!! The only message I got was: Alert! The AC power adapter wattage and type cannot be determined. The battery may not charge. The system will adjust the performance to match the power available. I know!!!... this does not sound logic, normally when your AC adapter is broken your laptop won't boot up but............ I test with a identical AC Adapter from other laptop and problem GONE . As the warning says "...The system will adjust the performance to match the power available" is complet
