Acer Aspire 3640 Power Adapter
When purchasing a replacement adapter, the actual Acer brand is usually going to be the safest choice. The Acer Aspire 3640 AC adapter provides two functions, to charge any and all batteries and to provide a source of power for the unit. A universal AC adapter is another possibility if you absolutely need to. If buying off-brand, please check on the output of amps and voltage. Due to the fact that one Acer adapter is most likely used on other laptop models, be sure you choose the right one.
Major warnings the Acer power adapter will not live much longer
- Your Acer battery refuses to charge completely
- The laptop does not run without the battery installed
- Most Acer adapters will get warm to the touch when they are plugged in for a period of time
