Gateway M405 Power Adapter
The Gateway M405 power adapter has two main uses, charging the battery and powering the laptop. When purchasing a replacement charger, the actual Gateway brand is always going to be the safest and easiest way to go. If buying off-brand, it is imperative to note both the voltage and amperage output. A universal power adapter is a possibility if yours is unavailable or backordered. Because Gateway has been known to use a single AC adapter that is probably used on other similar units, be sure you choose the right one.
Symptoms the power charger will need to be replaced
- Battery does not charge up completely
- Most Gateway adapters get warm when plugged in for 10 minutes or more
- The laptop does not operate using just the AC power adapter
