Lenovo ThinkPad 4300 Power Adapter
The Lenovo ThinkPad 4300 power adapter provides two functions, charging the battery and powering the laptop. Due to the fact that one Lenovo adapter powers multiple other machines, be sure you choose the right one. If you decide to buy an non-Lenovo adapter, it is imperative to note both the voltage and amperage output. A universal power adapter can be used if you are desperate. When purchasing a replacement AC adapter, the actual Lenovo brand is always going to be the safest and easiest way to go.
What symptoms are present when the charger has to be replaced?
- Most Lenovo adapters will get very warm to the touch when plugged in for any length of time
- The laptop does not run without the battery installed
- Battery does not charge up all the time
