What does an Inverter Cable do in a laptop computer?
Posted on 2006-04-02
I have a compaq evo N400c that will not use any battery, therefore it is no longer a mobile laptop as it always needs to be tethered to an ac outlet with the ac adapter.... this laptop runs sweet on the ac adapter, but once you unplug it it dies in less then five minutes, when a battery (fully charged) is inserted, the icon still says AC Power, and as it does not really recognize the battery, it warns of low battery and shuts down. Someone is trying to sell me an inverter cable and claims this will solve my problem if I can have someone install it in my laptop. The cable is $6 and well worth it if in fact it will solve this problem, however, when I ran the problem initially on ee I was told the problem was with charging circuit built into the motherboard. I have two of these laptops that have this problem and two that work fine with the batteries, so I need to repair two and want to know if this sound like the right fix?
