We use Klear Screen

How do I clean my screen?

We often get asked this question and for good reason. You want to remove finger prints, dust and other grime from your screen but don’t want to damage the finish. What about a Glossy finish? Or how about LED vs. LCD?

While there are many different methods, we use Klear Screen spray and a micro-fiber towel to clean our displays.

A bottle of Klear Screen lasts a long time, has a good consistency (doesn’t drip) and is Ammonia and Alcohol free. A micro-fiber towel is lint free so the result is a nice clean screen. We use this method with both LED and LCDs and matte and glossy finishes.

While it’s true a little water can do the trick, the connivence and consistency of a good screen cleaner is well worth the money.

Rule of thumb is to stay away from glass cleaners. If the display is covered in hair and crumbs (which we see quite often) a little canned-air before hand can reduce the risk of scratching the screen during cleaning.

PowerBook G4 15" Aluminum Battery

Symptom: Laptop not powering on (seems dead) even with the AC adapter plugged in and won’t charge the battery.

Cause: Some laptops need the battery installed with at least some charge left to boot and charge.

Macs Affected: PowerBook G4 15″/17″ Aluminum

Solutions: Install another battery with some charge left and then hot swap your old battery back in while the AC is connected or charge your battery in a friends book by hot swapping your battery or use an external battery charger or purchase a new battery.

This issue usually manifests itself after there is an issue with the DC-In Board. With the unit no longer able to charge, the laptop battery will become completely drained. After the new DC-In is installed the unit will not boot or charge because the battery is dead causing a Catch-22.

Note: MacBooks and MacBook Pros sometimes won’t boot without their battery depending on the condition and charge of their PRAM battery.
