Lenovo ThinkPad R30 Power Adapter
The Lenovo ThinkPad R30 AC adapter is needed for two reasons, to charge up the main battery and to provide a source of power for the unit. If buying off-brand, it is imperative to note both the volts and amps outputs. When purchasing a replacement AC adapter, selecting the Lenovo OEM charger will probably be the safest way to go. Because Lenovo has been known to use a single AC adapter that powers multiple other machines, be certain to thoroughly note the part number that is needed for this model. A universal AC adapter is a possibility if yours is unavailable or backordered.
Hints the Lenovo power adapter is failing
- Battery does not charge up all the time
- Most Lenovo AC adapters will get very warm to the touch when plugged in for 10 minutes or more
- The laptop does not function using just the AC power adapter
