Acer Aspire 9400 Power Adapter
When choosing a new charger, the actual Acer brand is the best one to choose. The Acer Aspire 9400 AC adapter is responsible for two things, charging the battery and to provide a source of power for the unit. A universal power adapter can be used but only if necessary. Because Acer uses one power charger that is probably used on other similar units, be sure you choose the right one. If buying off-brand, it is imperative to note both the voltage and amperage output.
What are some indications that my laptop charger needs replacing?
- The unit will not function while solely using the AC adapter
- Most Acer AC adapters can get quite warm when plugged in for 10 minutes or more
- Your Acer battery refuses to charge completely
