Lenovo ThinkPad T42 Power Adapter
Because Lenovo uses one power charger that powers multiple other machines, be sure you choose the right one. When choosing a new AC charger, the actual Lenovo brand is always going to be the safest and easiest way to go. If buying off-brand, make note of both the voltage and amperage output. A universal AC adapter is a possibility if you are desperate. The Lenovo ThinkPad T42 AC adapter has two main uses, to charge the onboard battery while simultaneously providing power for the laptop.
Simple signals the Lenovo power adapter is dead
- Most Lenovo adapters can get quite warm when plugged in for any length of time
- Battery does not charge every time
- The unit will not work while solely using the AC adapter
