Great laptop for several years until abruptly it wouldn't start. Blue and orange lights flashed in a pattern that apparently no one has deciphered. Occasionally it would boot and I would frantically upgrade drivers, BIOS, etc. But when I needed to reboot it was almost impossible to get it to start again. Hardware was replaced, Google (and Bing!) consulted but it was not to be. This isn't an uncommon Acer condition, either- read about it. Anyway, I take daily backups so I said goodbye to Acer, bought a Dell, and restored my system to a new, hopefully more reliable laptop.
