My Mac won't start up!

When your Mac refuses to start up it is generally due to a few different reasons. The most common, and unfortunately the one that most people are least prepared for, is a failed hard drive. If your Mac's drive fails, it will completely refuse to boot. There is a chance that unless you have a backup you will have lost your files, If this happens, contact us about data recovery services and don't turn it back on.

If your Mac is a Macbook Pro, made between 2008 and 2011, the second most common issue that will stop it from booting is an overheated Graphics Processor. The GPU's in these Macbook Pros ran too hot for the cooling solution that Apple put in these computers. The GPUs in these systems were Ball Grid Array Flip-Chips, which are computer chips that sit on a grid of balls made of solder instead of pins. This allows them to take up less space, but means that when they heat up a lot the solder balls can reflow into a puddle, ruining the GPU.

Smashed Mac 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. Mac screens have a layer of glass in front of the LCD panel which is frequently the part that is damaged. If your glass is cracked but your panel is okay, you're in luck as the repair is much less expensive. Replacing the entire LCD assembly on a new Mac is super expensive, and many times isn't worth doing. Call us for a quote and we will let you know.

Battery Life Fact and Fiction

Mac batteries, just like PC batteries and 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 Mac's battery is no longer holding a charge, or if the charge it is holding is substantially reduced, you should replace it.
