Lenovo ThinkPad X21 Power Adapter
If you decide to buy an non-Lenovo adapter, make note of both the volts and amps outputs. The Lenovo ThinkPad X21 power adapter provides two functions, to charge up the main battery and to provide a source of power for the unit. A universal AC adapter is a possibility but only if necessary. Because Lenovo uses one power charger that can be used on other units, be certain to thoroughly note the part number that is needed for this model. When choosing a new charger, selecting the Lenovo OEM charger is always going to be the safest and easiest way to go.
What red flags are there that my charger is crapping out?
- Most Lenovo adapters can get quite warm when they are plugged in for a period of time
- Your Lenovo battery refuses to charge all the time
- The unit will not work while just using AC power
