Hi, just borrowed my moms laptop (ASUS Pro 60 series A6M) doing updates ~~and playing with dual cores~~.

I just touched the psu power pack at it's really hot, not burning but like a hot tap (75c),
is this normal? It is on a charge cycle, would that make it hot?

What are some solution to reducing it's temperature?

thanks
Brett

Must be an AMD laptop. They can consume over 100W of energy in ACPI C1 state, ie when running on mains they use more power and make more heat. with the small, unventilated, switchmode power-packs you can expect alot of heat, its normal unless any plastic shows signs of melting, that would obviously be a concern. try and use the battery as much as possible, it will be cooler while doing so (and a battery that never gets used won't last as long).

could you attach a heatsink to it? there are 'laptop cooling pads' available at online stores which may help but a $5 heatsink from DSE or Jaycar could work just as well.

howdy

I've got a similar laptop, Asus A6M but wasn't too sure about battery use vs. mains... so you'd recommend running it on batteries and running the battery down to minimum, plug in to recharge then unplug again?
