Let me help. I have an ACER and I'll be happy to help with the cons. The power switch is failing on mine. It's so bad that I log off and flip the switch on the surge protector. Otherwise, I may never get the gosh darn thing back on. Given the costs of repair, I just may have to replace it because of a dinky little switch.
I checked in with the repair shop, and the cost of a jury rigged repair is greater than the value of the computer. I contacted ACER parts for a replacement, and it turns out they don't sell or make a separate switch. It is a part of the "front bezel", which can probably be ordered for 39.95 + shipping. Then you gotta add in the shop charge.
By the way, the repair guy checked his sources and couldn't find a switch, but he did learn that switches are a big issue with ACER products. Newer models may be using higher quality parts, but this is not a good indication. Also, the power switch on the monitor is a little problematical, too.
If you check my profile, you will find a thread I started on this very issue.
Thanks for asking. I am not bashful about sharing my experience with ACER.
