Sony VGN-NR320E Power Adapter
The Sony VGN-NR320E AC adapter is needed for two reasons, to charge up the main battery while simultaneously providing power for the laptop. Upon choosing a replacement AC charger, selecting the Sony OEM charger is always going to be the safest and easiest way to go. Due to the fact that one Sony adapter powers multiple other machines, be sure you choose the right one. A universal AC adapter is a possibility if you are desperate. If buying off-brand, it is imperative to note both the voltage and amperage output.
Clues to watch for to know your laptop charger has to be replaced
- Most Sony adapters get warm when plugged in for 10 minutes or more
- The laptop does not work while solely using the AC adapter
- Battery does not charge up every time
