Acer Aspire 7540 Power Adapter
If your decision is to purchase a different brand charger, please check on both the voltage and amperage output. When purchasing a replacement AC adapter, choosing the Acer brand one will probably be the safest way to go. Because Acer has been known to use a single AC adapter that powers multiple other machines, be sure you choose the right one. The Acer Aspire 7540 power adapter provides two functions, to charge up the main battery while simultaneously providing power for the laptop. A universal power adapter is another possibility if you are desperate.
Simple warnings that your Acer power adapter is not working properly?
- The unit will not work while just using AC power
- Your Acer battery refuses to charge up every time
- The majority of Acer power chargers will get warm to the touch when plugged in for 10 minutes or more
