Lenovo E43 Power Adapter
The Lenovo E43 power adapter has two main uses, to charge any and all batteries while simultaneously providing power for the laptop. Because Lenovo has been known to use a single AC adapter that powers multiple other machines, make sure you check the part number for the correct one. If buying off-brand, it is imperative to note the output of amps and voltage. When purchasing a replacement adapter, the actual Lenovo brand is always going to be the safest and easiest way to go. A universal AC adapter can be used if you are desperate.
Some warnings of a weakening AC adapter
- Most Lenovo AC adapters can get quite warm when plugged in for 10 minutes or more
- The laptop does not function while solely using the AC adapter
- Your Lenovo battery refuses to charge up every time
