Toshiba Satellite R840 Power Adapter
The Toshiba Satellite R840 power adapter has two main uses, charging the battery and powering the laptop. Because Toshiba has been known to use a single AC adapter that can be used on other units, be sure you choose the right one. When purchasing a replacement adapter, selecting the Toshiba OEM charger is always going to be the safest and easiest way to go. If your decision is to purchase a different brand charger, please check on both the voltage and amperage output. A universal AC adapter can be used if you are desperate.
What are some hints that my AC adapter will soon go out?
- The laptop does not function using just the AC power adapter
- Most Toshiba adapters can get quite warm when they are plugged in for a period of time
- Battery does not charge up every time
