Lenovo ThinkPad 4299 Power Adapter
When choosing a new adapter, selecting the Lenovo OEM charger is always going to be the safest and easiest way to go. The Lenovo ThinkPad 4299 power adapter provides two functions, to charge up the main battery while simultaneously providing power for the laptop. A universal power adapter can be used if you are desperate. Due to the fact that one Lenovo adapter powers multiple other machines, be sure you choose the right one. If buying off-brand, please check on the output of amps and voltage.
Clues the power charger needs replacing ASAP
- Most Lenovo AC adapters get warm when they are plugged in for a period of time
- Your Lenovo battery refuses to charge up completely
- The unit will not function while just using AC power
