Lenovo ThinkPad 770X Power Adapter
When choosing a new AC adapter, the actual Lenovo brand is usually going to be the safest choice. If your decision is to purchase a different brand charger, make note of the output of amps and voltage. Because Lenovo uses one power charger that can be used on other units, double-check the part number or model number of the adapter. The Lenovo ThinkPad 770X AC adapter has two main uses, to charge up the main battery while simultaneously providing power for the laptop. A universal AC adapter can be used if you absolutely need to.
Hints the power charger is dead
- The majority of Lenovo power chargers can get quite warm when plugged in for 10 minutes or more
- The laptop does not work using just the AC power adapter
- Your Lenovo battery refuses to charge at all
