Acer Aspire 4920 Power Adapter
If you decide to buy an non-Acer adapter, please check on both the volts and amps outputs. When purchasing a replacement charger, choosing the Acer brand one will probably be the safest way to go. A universal power adapter is another possibility if you are desperate. Because Acer has been known to use a single AC adapter that powers multiple other machines, make sure you check the part number for the correct one. The Acer Aspire 4920 power adapter is responsible for two things, to charge up the main battery and powering the laptop.
Subtle hints the Acer power adapter is going to die
- Battery does not charge up whatsoever
- The laptop does not work using just the AC power adapter
- Most Acer adapters will get warm to the touch when plugged in for any length of time
