Many laptops were designed for use by a person. Not to run as a server. To get around this you leave the battery in since it's the UPS, then you place it on a laptop cooling pad or one of your own homemade cooling pads.
I have bought my first laptop (HP DV 6701 AU) about 3 weeks back.
Right now am running it on AC power directly with battery removed, I have also bought an USB cooling pad (basically a stand with 3 fans underneath it).
I have 256 Kbps unlimited conn from IOL. So my laptop is on about 18 hours a day daily.
One of my friends told me that keeping laptop running for extended periods of time would harm the laptop (speakers would go bad after some time, processor might be effected etc)
I would like inputs from the members here about this.
