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!

Oh- and HP says the power supply isn't warrantied... WHAT??? They sent me a new AC brick, but neglected to send the 2nd half of the power source- the part that plugs into the wall. So I'm having to use the plug end of the old power source (the one that melted!)... when it could be THAT end of the power cord that is faulty.

UGH. I'm so NOT a computer person.

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!!

Is it still running hot with the battery disconnected?

(you can run the computer with no battery as long as it is plugged into the wall)

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.

either that, or when you use it slap some heatsinks on that thing...
there's no way anything should melt. at all.

but, try running without the battery, as stated, and see if it gives you the same issue.
my guess is your battery is severely shorted or damaged.

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!
