Acer Aspire 3690 Power Adapter
Upon choosing a replacement charger, choosing the Acer brand one will probably be the safest way to go. If you decide to buy an non-Acer adapter, make sure to check both the voltage and amperage output. Due to the fact that one Acer adapter is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model. The Acer Aspire 3690 power adapter provides two functions, to charge up the main battery while simultaneously providing power for the laptop. A universal AC adapter is another possibility but only if necessary.
What are the signs that the laptop charger is about to fail?
- Battery does not charge at all
- The majority of Acer power chargers get warm when they are plugged in for a period of time
- The laptop does not function without the battery installed
