The laptop was great for a while. One day it wouldn't boot when my daughter tried to use it. I looked up the code from the flashing lights, and it was a memory error. I tried to re-seat the RAM, thinking that maybe a loose connection was the cause. This didn't work. I assumed that one of the RAM cards was bad, so I ordered another. No luck. Turns out that the motherboard failed, and will not boot with any RAM in one of the slots. We're outside of the warranty period, and failure in less than a year is very disappointing.
