Lenovo ThinkPad W541 Power Adapter
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. If your decision is to purchase a different brand charger, make sure to check both the voltage and amperage output. A universal power adapter is a possibility but only if necessary. The Lenovo ThinkPad W541 AC adapter provides two functions, to charge any and all batteries while simultaneously providing power for the laptop. When purchasing a replacement adapter, the actual Lenovo brand is always going to be the safest and easiest way to go.
Clues your laptop charger will not live much longer
- The majority of Lenovo power chargers get warm when plugged in for 10 minutes or more
- The unit will not operate while just using AC power
- Battery does not charge every time
