Lenovo ThinkPad 4289 Power Adapter
Upon choosing a replacement AC charger, the actual Lenovo brand is always going to be the safest and easiest way to go. If your decision is to purchase a different brand charger, make sure to check both the voltage and amperage output. The Lenovo ThinkPad 4289 AC adapter has two main uses, charging the battery and to provide a source of power for the unit. Because Lenovo uses one power charger that is probably used on other similar units, make sure you check the part number for the correct one. A universal AC adapter is another possibility if you absolutely need to.
Major signs of a faulty power adapter
- The laptop does not work without the battery installed
- Battery does not charge all the time
- Most Lenovo adapters can get quite warm when they are plugged in for a period of time
