Lenovo IdeaPad N581 Power Adapter
Due to the fact that one Lenovo adapter is probably used on other similar units, be sure you choose the right one. The Lenovo IdeaPad N581 power adapter is responsible for two things, to charge up the main battery while simultaneously providing power for the laptop. If you decide to buy an non-Lenovo adapter, it is imperative to note both the voltage and amperage output. When purchasing a replacement adapter, the actual Lenovo brand will probably be the safest way to go. A universal power adapter is a possibility but only if necessary.
Simple signals your power adapter has very little life left
- Most Lenovo AC adapters will get warm to the touch when they are plugged in for a period of time
- The unit will not work while solely using the AC adapter
- Your Lenovo battery refuses to charge up every time
