Acer Aspire 5740 Power Adapter
Upon choosing a replacement charger, the actual Acer brand is always going to be the safest and easiest way to go. Because Acer uses one power charger that powers multiple other machines, be sure you choose the right one. The Acer Aspire 5740 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 but only if necessary. If buying off-brand, it is imperative to note both the voltage and amperage output.
Important signs your power adapter is on its last leg
- Your Acer battery refuses to charge completely
- The laptop does not run without the battery installed
- Most Acer AC adapters get warm when plugged in for 10 minutes or more
