Sony VGN-FZ420E Power Adapter
When purchasing a replacement AC charger, selecting the Sony OEM charger is always going to be the safest and easiest way to go. The Sony VGN-FZ420E AC adapter is responsible for two things, charging the battery and to provide a source of power for the unit. A universal power adapter is a possibility if you absolutely need to. If your decision is to purchase a different brand charger, make note of both the voltage and amperage output. Due to the fact that one Sony adapter powers multiple other machines, be sure you choose the right one.
What red flags are there that my charger is on its last leg?
- Battery does not charge whatsoever
- Most Sony adapters will get warm to the touch when plugged in for any length of time
- The unit will not work using just the AC power adapter

A Sony VGN-FZ420E power adapter should be purchased new due to possible wear on any older used one. It is in your best interest to note the manufacturers part number before buying a power adapter replacement. Always purchase computer products from a well-known website if you buy anything online. Your Sony laptop will be better off for buying the right part!
