Toshiba Satellite S40-B Power Adapter
The Toshiba Satellite S40-B power adapter has two main uses, to charge up the main battery while simultaneously providing power for the laptop. If buying off-brand, please check on the output of amps and voltage. Because Toshiba 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. Upon choosing a replacement adapter, choosing the Toshiba brand one will probably be the safest way to go. A universal AC adapter is another possibility if yours is unavailable or backordered.
Clues your AC adapter has little time left
- Battery does not charge every time
- Most Toshiba adapters can get quite warm when they are plugged in for a period of time
- The unit will not operate without the battery installed
