AC adaptor for laptop melted!

Hi! I just purchased a compaq presario F577CL. The AC adaptor runs SUPER hot (I tested it with a thermometer). After being plugged in for 12 minutes, it maxed my thermometer out at 112 degrees. HP mailed me a new one, as that one literally melted the cord. The replacement runs just as hot! The battery only holds a 20 minute charge...

I'm not a computer person... but is a 20 minute charge a reasonable charge for a NEW battery? Do laptop AC adaptor/chargers normally run THAT hot?

I think I bought a lemon...

Help!

20 mins?

That's ridiculous, even the most power hungry monster laptops should get at least an hour. Yours should be getting more like 2 hours or so, minimum.

Something is seriously wrong. Try removing the battery and powering it from the wall, and see if it still gets just as hot.

I contacted HP... they sent me a new battery. However, the AC adaptor is still running really hot. I had a different thermometer and checked it got up to 120 degrees!!

120 is not out of the ordinary for a power brick. 120 isn't really that hot, it can't burn anything but to humans it feels "burning". Mine is about 100 right now. If it actually melted a cable then you are way above 120.

O Crap! you probably mean Celsius! That is really hot!!! Take that thing back before you burn down your house.

Thanks for all your advice!!

I got a new battery and AC adaptor, free of charge, from HP... but the AC brick is still running hot. But, the new battery holds a decent charge.

I guess I can't expect too much... I got a great deal on the laptop. It was the floor model, had a price of $799 and they marked it down to $450! Plus, they gave me a $150 gift card!
