I recommend acer products before but when I encounter problems with my iconia a500, I don't know how to recommend it again, my a500 is only 1 and a half year old but it doesn't boot anymore and when I check to acer forum many iconia users encounter the same problem, I already sent it to acer but they tell me that they need to replace the mainboard for almost 15k, but I think it is not the user fault because most of the case the the problem come out with its OS update and maybe it has poor memory problem that cuasing the unit not boot again.... If ACER really care for there costumer they must investigate and try to resolve with this issue... hoping that this issue will help other iconia users....
Scratch that! Ladies and gentlemen, we have a culprit!! Some of us just have dead batteries due to a bad connector. Move the connector slowly around and lightly pull it in and out while watching the power button. The button turns red or orange when the charger is properly connected. The tab may show it is connected and charging in the settings and the battery icon even though it is not charging. The power button color tells the real tale. If the button is flashing white, that means the battery is low and not charging and the tab will soon shutdown. The tab stops at the Acer screen during boot because the battery does not have enough power to start. The power port is either bad or needs a good cleaning. If your tab shows a steady red or orange light and it still won't boot, you need a battery. I've been working on this for about 3 days straight, now I can get some real sleep while my tab is charging. My earlier post was not entirely wrong, I had just had a technical glitch. No sleep and a false positive caused me to jump the gun. Get them fixed people. It's not as bad as having a brick!

I am yet ANOTHER of the misfortunate owners of an Acer 500a Iconia Tablet that froze up on the Acer Bootup screen just several WEEKS after the warranty expired. There are HUNDREDS if not THOUSANDS of us with the same issues, as I've been reading a lot of the posts on here. Some solutions work for some, others don't work at all. I've tried "reseting" the tablet, I've tried "hard-resetting" the tablet, and I've also tried reseting back to factory settings- the end result IF ANYTHING is a dead android with a red triangle w/exclamation mark. Apparently, Acer doesn't give a rats a*s about its customers, because no one to date has received ANY recompense or fix from Acer.
Suggestions: If Acer continues to refuse to fix this WIDE-SPREAD issue, as they have so far, here are some suggestions:
Contact the Better Business Bureau and file a complaint. You can find the one for your area by going to: www.BBB.org I also suggest that you contact your state's Attorney' General's Office, as this is the type of thing they investigate and do something about.
If you file a complaint with either of the above, be sure to Include the link to this forum to show just how wide-spread the issue is and how Acer continues to ignore the issue.
Since this previous post seemed to have helped many, I have copied it again for those that have missed it. Maybe it will help YOU, unfortunately, it sure didn't help me:
I also found this possible solution to the same issue on an XDA forum site. I'm copying and pasting the relevant information. I am first going to try doing the first update as suggested in an older post (see above, wasn't posted that long ago in relation to my post). Will keep posted if any works:
