Lenovo ThinkPad Edge E445 Power Adapter
Because Lenovo has been known to use a single AC adapter that is probably used on other similar units, make sure you check the part number for the correct one. If your decision is to purchase a different brand charger, it is imperative to note the output of amps and voltage. A universal AC adapter can be used but only if necessary. The Lenovo ThinkPad Edge E445 power adapter is responsible for two things, charging the battery while simultaneously providing power for the laptop. When choosing a new charger, selecting the Lenovo OEM charger is usually going to be the safest choice.
Major symptoms your AC adapter is in dire need of a replacement
- The unit will not operate while just using AC power
- The majority of Lenovo power chargers will get warm to the touch when plugged in for 10 minutes or more
- Battery does not charge up every time
