HP Elitebook 8440p overheating

HP Elitebook 8440p overheating

You can get used 8440p laptops pretty cheaply because HP Elitebook 8440p overheating is rather common. Symptoms of overheating include unexpected reboots, shutting down, and bluescreens.

The problems with the cooling system are unfortunate. They have nice keyboards, they’re easy to work on, and they’re reliable otherwise, so they’d be nice laptops if they didn’t overheat so much. Here’s how to improve their cooling so you can get a bargain–buying off-lease business laptops is a great way to save money.

HP Compaq 6910p upgrades

HP Compaq 6910p upgrades

I spent some time exploring HP Compaq 6910p upgrades because used HP Compaq 6910p laptops are dirt cheap these days. I picked one up for $75 as an alternative to a Black Friday cheapie.

If you look for one yourself, either look for one with a valid Windows 7 or Windows 10 license on it, or get one at a deep enough discount to make it worth your while.

Here’s what I did to turn an outmoded laptop from 2008 into something better than what I could have bought on Black Friday.

Computer burn in explained

Computer burn in explained

I’ve worked several different shops now that seem to have a misconception about computer burn in. So I’m going to explain it.

I think there’s a misconception that if you let a computer run with a light load for a while, it somehow gets stronger, and ready to handle a big workday load.

I’m 5’9″ and weigh about a buck-fifty, so trust me, I know a non-bodybuilder when I see one. And computers aren’t bodybuilders. Read more

Will running Prime95 void my warranty?

Here’s a good question: Will running Prime95 void my warranty? I have the answer to that. I run Prime 95 on every new computer I get, so that probably tips you off.

The short answer is no, and, in fact, I ran it about 30 hours straight on my newest computer. I started it on Friday before I left for work. I let it run until I got home from running errands on Saturday. All told, it probably ran 30 hours. If a computer is going to fail, I want it to fail before I’m depending on it for something.

Cheap laptops and tablets: September 2011

My brother in law told me he saw an 8-inch Vizio wifi-only tablet running Android at Costco for $285. Its reviews aren’t exactly stellar, but if you just want a basic tablet, it seems to be OK. I’d wait a few months and see what Amazon’s tablet plans are, though.

He also asked about laptops. And there’s some good stuff going on in the low end there too.

Stress test computer hardware with Prime95

Let’s say you’ve just bought a used PC with a short (typically less than 2 weeks) warranty. Or a new PC that’s not the brand you know and trust. Maybe you’ve built a new PC and you want to make sure it’s going to hold up before you start using it every day. Or you have a new server, and you want to make sure it’s going to hold up under heavy loads. What should you do to stress test computer hardware (or burn in computer hardware) like that?
