Lenovo ThinkPad X1 CARBON 34XX Power Adapter
If you decide to buy an non-Lenovo adapter, make note of the output of amps and voltage. The Lenovo ThinkPad X1 CARBON 34XX AC adapter is responsible for two things, to charge up the main battery and to provide a source of power for the unit. Because Lenovo has been known to use a single AC adapter that is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model. Upon choosing a replacement charger, the actual Lenovo brand is always going to be the safest and easiest way to go. A universal AC adapter is a possibility if you absolutely need to.
Major indications your laptop charger is dying
- The unit will not run while just using AC power
- Your Lenovo battery refuses to charge up all the time
- The majority of Lenovo power chargers will get warm to the touch when plugged in for 10 minutes or more
