Lenovo ThinkPad 4290 Power Adapter
The Lenovo ThinkPad 4290 AC adapter is needed for two reasons, to charge the onboard battery while simultaneously providing power for the laptop. If you decide to buy an non-Lenovo adapter, please check on both the volts and amps outputs. Upon choosing a replacement AC charger, selecting the Lenovo OEM charger is usually going to be the safest choice. A universal power adapter can be used if you are desperate. Because Lenovo has been known to use a single AC adapter that is probably used on other similar units, double-check the part number or model number of the adapter.
Important hints the Lenovo power adapter will need replacing
- Battery does not charge at all
- Most Lenovo adapters will get very warm to the touch when plugged in for any length of time
- The laptop does not operate without the battery installed
