Hardware Troubleshooting and repair

Is your computer making a strange noise? Clicking, buzzing or beeping? Is it randomly shutting off when you're in the middle of using it? Does the battery no longer hold a charge? Is the screen cracked or completely broken?

My Computer Randomly Shuts Off

Over time the fans in your computer suck up dirt, dust and pet hair. This detritus clogs up the heatsinks that keep your computer's CPU and graphics processor cool. It also increases the operating temperature of your computer's power supply, ram and hard drive, all of which are sensitive to high heat.

When your computer senses that it is running hotter than it should be, the first thing it does is throttles down the speed of the hot component if possible. You will especially notice this during gaming or playback of full motion video, as it will become very choppy and unresponsive out of nowhere. If the heat continues to increase and it exceeds a threshold determined by the manufacturer of the hot component, the computer will shut itself off to prevent permanent damage. It will usually do this if you're in the middle of something and you haven't saved in a while.

It can be difficult to clean the heatsink in a laptop, as most of the time there is no easy to way to access it through the bottom of the computer. Instead, the whole laptop must be disassembled, and the keyboard, screen and motherboard removed to provide access to the cpu cooler. Having your computer cleaned once or twice a year, or even more frequently if you spend a lot of time in dusty or pet filled areas, is a great way to substantially extend the useable life of your system and avoid costly problems in the future.

Smashed LCD

My Screen is Broken!

Cracked or shattered laptop screens should be replaced as soon as possible. Shards of glass from the screen can cause injury, and a broken screen isn't usable at all. The good news is that replacement LCD screens for laptops have come down in price substantially, and most laptops can have their screens replaced for under $200.

Battery Life Fact and Fiction

Laptop batteries, as well as smartphone batteries are generally all members of the lithium-ion battery family. They use Lithium Cobalt Oxide as their energy storage material, because it offers high energy density and light weight. Unlike older batteries like the Nickle-Cadmium batteries previously used in drills and flashlights, Lithium-Ion batteries don't suffer from any memory effect.

There are a lot of misconceptions about how one should maintain their laptop's battery. Most of these misconceptions are holdovers from the Nickle-Cadmium batteries of the past. These batteries are very different, and treating them otherwise will substantially reduce their life.

Battery Life

A Lithium-Ion battery's life is measured in charge cycles. A charge cycle is defined as discharging the battery from 100% to 0%, and then recharging it back to 100%. Every battery can be expected to last for a fixed number of charge cycles, typically measured in the thousands. Discharging the battery to 50% and then recharging it only counts as half of a charge cycle, and as a result it is in the user's best interest to keep the battery charged as much as possible to minimize the number of charge cycles consumed. Lithium Ion batteries like thos found in your cellphone and laptop hate being discharged to 0%, and this should be avoided at all costs.

This is directly opposite of Nickle-Cadmium batteries, and in fact treating a NiCD battery like this would ruin it. Since most people who have owned battery powered drills in the past 20 years have had the idea of fully discharging their battery before recharging burned into their brain, it is common to hear advice that one should do the same with a laptop or cellphone battery.

If your battery is no longer holding a charge, or if the charge it is holding is substantially reduced, you should replace it. Just like LCD screens, Lithium Ion battery prices have declined substantially. In fact, most laptop or smartphone batteries can be replaced for around $50.
