That's very strange.
I read only one other instance of someone reporting 'hotness/heating'.
And they didn't mention the screen going crazy.
What happens if you just switch the screen on and off?
Was a charger plugged in? wall charger? usb cable?
I've noticed this too, but nothing I was alarmed about.
I was sitting outside yesterday and was reading my fully-charged, practically-new Nook+ HD...after about 15-20 minutes a big overheating symbol appeared on the screen and it shut down immediately. It felt very hot at the top end where the volume buttons are. I checked entire user guide but could only find temperature guide, top end of which is 95F. It was a nice, pleasant, sunny Florida afternoon, but in no way was it a very hot day and the sun was not very hot. I fully charged it and was watching NetFlix last night and noticed battery charge was down to a half after watching for 90 minutes. I will have to watch very closely in the next week or so. I'm very disappointed in my purchase so far.
nacholulu, it might be due to being in direct sunlight. I haven't heard of this before with Nook but have heard that some Kindle Fires heat up SUPER fast if kept in direct sunlight for more than 25-30 minutes.
I really regret getting a HD because of the heating problems. I've already had to exchange one because of it and now the second one is starting to get worse.
Out of curiousity, how many of you out there with heating problems are left-handed? When I returned my first one, the employee mentioned that the processor is on the right hand side- right where a lefty would be holding it while typing or whatever with their left hand...>_>
I had to return my HD+ because it was overheating. I was using it inside ina chilly living room on New England, so it wasn't ambiet heat or sun! I am right handed. I often use it when I'm curled up in my Poang chair with it leaning against my leg. Never used it for more than an hour and a half, maybe a tad more, at a time. When I brought it back to the storre, I ran it for an hour beforehand so that it was quite warm when I showed it to them. They seemed genuintely surprised (and I really DO trust these people) and exchanged it on the spot. So far, I have not had issues with the new one. Mine heated on the lower left hand side.
Same thing happened to me yesterday and I also live in Florida and I am on my second nook replacement (probably third when I take this back to BN.
I purchased my nook in November and I'm so sorry I did.
I had to replace it once due to magazines not uploading and tonight I'm going to BN to check out why this thing keeps overheating.
I'll keep you posted and please let me know what goes on with yours too.
I should of bought a KINDLE :-(
Mine has been overheating alot lately, usually when I am playing a game. Causes? Fixes? Thank you!
Mine overheats when i do anything more than read with wifi off and brightness set to abt 30%. Deff can't read while charging. Tried that once and the metal arear of the cover got so hot it could burn you.
Hi everybody, sorry for my poor english. I'm from Spain.
I've got a Nook hd+ whith this problem but the first days the nook was OK lately de back was getting really hot from down to top and was very dificult handle it, almost burn.
Since I removed the micro sd hd card (sandisk 16 gb) from the slot the problem is gone. The card is a simple card for expand memory not for running a OS.
I hope this tip may be usefull.
I just noticed my nook hd+ getting hot also, but my screen did not go crazy as you described, mine just keeps restarting itself.
I just had the update on my HD+ and it's been doing the same thing! It gets really hot and crashes. Once it even showed the overheating sign and shut down and I was indoors with the air conditioner on. I did the online tech support chat and they had me do some stuff and that just made it worse, it w2ouldn't shut off and kpet going from the Nook screen to the home screen and back again, so I called and tech support had me do a factory reset but it didn't help. I can't play any of my games now because of this. And it's only been since the update which was sometime at the beginning of last week I believe. I don't have the problem when watching Netflix or reading, only with games. I did take it out of the case last night and so far it's only crashed on me once and it doesn't seem to get nearly as hot not being in the case. I hate to not use the case though, I dont want scratches or damage.
I just got it in May and it was working perfectly this whole time until the update. I tried looking for "after update" issues but I'm not finding anything recent.
I noticed with mine if I took it out of the house it was constantly searching for wifi and would get hot at the bottom left in portrait mode. If I turned off wifi, or connected to a open wifi it would no longer heat up. The only other time it gets warm is playing graphics intensive games like Real Racing 3. or playing movies that where poorly coded.
I have had a Nook HD+ since May 2013 and have been frustrated by overheating issues, especially when playing games. It's not much of an issue when reading or watching movies, but any kind of game causes it to get quite warm, and more intensive games cause it to get very hot and restart, usually unexpectedly. This is whether or not it's plugged in. This happens every time I play more intensive games (e.g. Big Fish, G5, etc.). Also some issues with slowing down and responsiveness, even after using an app killer, restarting, etc. May be related.
I'll continue reading through the responses to see if there are any solutions that I haven't tried.
