Lenovo IdeaPad U300 Power Adapter
If you decide to buy an non-Lenovo adapter, make note of the output of amps and voltage. Because Lenovo has been known to use a single AC adapter that can be used on other units, double-check the part number or model number of the adapter. When choosing a new adapter, selecting the Lenovo OEM charger is usually going to be the safest choice. A universal AC adapter is a possibility but only if necessary. The Lenovo IdeaPad U300 power adapter is needed for two reasons, charging the battery and to provide a source of power for the unit.
Major indications to watch for in a bad AC adapter
- The unit will not run without the battery installed
- Most Lenovo AC adapters will get very warm to the touch when plugged in for 10 minutes or more
- Your Lenovo battery refuses to charge up at all
