Gateway 400SD4 Power Adapter
Upon choosing a replacement AC charger, choosing the Gateway brand one is always going to be the safest and easiest way to go. Due to the fact that one Gateway adapter is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model. A universal power adapter is another possibility if yours is unavailable or backordered. The Gateway 400SD4 AC adapter is needed for two reasons, to charge up the main battery and powering the laptop. If your decision is to purchase a different brand charger, make note of the output of amps and voltage.
Easy warnings the power charger has to be replaced
- The laptop does not work using just the AC power adapter
- Your Gateway battery refuses to charge up at all
- Most Gateway AC adapters can get quite warm when plugged in for any length of time
