Laptop power supply.

By mgradybruin ·
How hot should my power supply be getting on my lap top? If I plug it in, the adapter and the power supplied seem to get extremely hot. the same thing happens with just using the battery. What should I do?

Laptop power supply.

first check with the manufacturer to see if this is a knowen problem I guarantee if you use a power supply larger than that supplied with the laptop it VOIDS the warranty.
You guys are nuts the dc-dc controler in the laptop controls charging and power distribution to the battery and system board the dc-dc controler is very precicely regulated on both the input and output sides a sizeable change in current might even cause the battery to get hotter while charging and discharging if there is a fuse inside the laptop it is a tiny square fuse solderd into a trace and 98% of computer techs would'nt know what it is and tell you the system board is bad, secondly if there is a fuse anywhere it is most likly on the ac side of the power brick and not inline on the dc side I might say you can go 5% higher on ampage but not any more.
ps: the last time I saw a buss fuse inside a laptop it was a 286 or a compaq armada laptop that you pluged 120v directly into the laptop and the power supply was in the bottom of the unit.
