Lenovo ThinkPad 42875TU 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 adapter, the actual Lenovo brand is usually going to be the safest choice. A universal AC adapter is a possibility if you absolutely need to. If buying off-brand, make sure to check both the voltage and amperage output. The Lenovo ThinkPad 42875TU power adapter has two main uses, to charge up the main battery while simultaneously providing power for the laptop.
How do you know if your laptop charger is about to fail?
- The majority of Lenovo power chargers will get very warm to the touch when plugged in for 10 minutes or more
- Your Lenovo battery refuses to charge completely
- The unit will not operate using just the AC power adapter
