I am a teacher and we use chrome books daily. However, I have 4 chrome books that have the exact same problem. It looks like a black screen, however the chrome book is turned on and brightness is at 100%. I can barley make out that the computer is working, however if I conect it to the projector I can see the display.
Thank you
Can i download Windows 10 to my Chromebook 11 Cb3-131?
1) How can I play CD / DVD with my CB3-111 ?
2) DVD Player by Philips: Any problems with this and a CB3-111 ?
Just bought a chromebook 15 CB5-571-C1VQ and it has 2GB soldered DDR3. I have seen that some Chromebook 15's are upgradeable and was wondering if the specific model I have includes an SODIM DDR 3 slot to stick another 2GB in. Dont really want to go invalidating warranty without cause or pay to take buy part and take to Acer Authorised centre to fit.
Many thanks in advance.
I just got my Acer Chromebook R11, and everything seems to work fine except the microphone. I need to put my face right next to the mic and yell into it in order for it to pick up any audio. Is there a way to adjust the microphone volume? Thanks!
I have a chromebox that i'm using as a supervised user, but the box keeps going to sleep. Can anyone tell me how to turn off the power saving features on this device? I found developer mode commands online for a notebook that do not work on the chromebox. We're trying to use this for an industrial application and every time it goes to sleep it's screwing up the weblink required for our system.
This is not an issue with the charger, I've used different chargers, but still had to press it very hard to charge. I'm very sure its a problem with the charging area on the chromebook. At first, I didn't have to press very hard, but it got worse and worse, and then I had to tape the charger in order to charge. Now, even with the charger taped, it is getting worse and worse, and will not charge at all sometimes.
The chromebook is 2 years old.
I followed the instructions here: https://acer.custhelp.com/app/answers/detail/a_id/27637#_ga=1.91117849.2058217069.1472158467
I went to Google's site, and downloaded the linux script which creates the bootable USB media. It passes the verification stage, then fails with an "Unexpected Error." I looked that up on the Google recovery page and it say my media could be bad. That isn't the problem. I watched the logs (using <CTRL><ALT><REFRESH>) and the failure happens when flashing the rom:

Please report this on IRC at irc.freenode.net (channel #flashrom) or mail flashrom@flashrom.org! ------------------------------------------------------------------------------- You may now reboot or simply leave the machine running.
It's acting like the flash program is expecting one chip, but detecting another.
Anyway, if this is the case, where can I get the correct firmware?
This is an Acer Chromebook 14:

Any help would be appreciated, since it's basically just a big paperweight right now.
Since new (about 3 months), my Chromebook 15 shuts down randomly after start-up. The only way to start it up again is to press the reload and power key simultaneously. After 4 or 5 cycles of shutdown and start-up, the computer will function properly until I close the cover for the day. Next day, the cycle starts all over again. I've tried power wash and brouser reset several times without success. Does anyone have a suggestion? I'm ready to try anything. Tech support has been no help so far.
I've searched about this and everyone seems to get the same responce of a PM with more information. So, I'd like more information on our school IT department doing our own chromebook repairs on our R11's.
Power light solid, battery light blinks 7 times before both lights shut off and repeat the pattern. When chromebook is open, I get no display on the screen.
Troubleshooting I have done.....
Reboot
"Esc" + "refresh" + "Power button" to force into dev mode. no success
Charge over night
Discharge battery. (Disconnect battery and power, hold power for 10 seconds, reconnect power, attempt to power on, then reconnect battery. No success.
Reseated LCD cable (for grins and giggles). After disconnected screen from back cover, I layed it down on keyboard (still having LCD cable connected) and saw backlight flickers after the sequence of beep codes. *flicker only occured while screen was down*
Tried replacing screen... no luck.
Before I swap the main board, has anyone seen this before? Been looking for information of beep/blink codes and I get nothing.
Thank you in advanced for your time.
I've tried using two different flash drives, a 16 gb by Kingston, and a 16 gb by Sandisk. Every time I try to recover OS, it says "an unexpected error has occured." This is right after it goes through verifying the integrity of my recovery media.
The recovery reason states "0x5b No bootable kernel found on disk"
At the time I only had the book for a few month's and it was working just fine till one night it decided not to cut back on after being charged. So, now a year later I decided to give it one more try and now it's working. What could it be?
I need a chromebook before October 16th and im really trying to wait for the R13 but I dont have an exact release date to work with.
I had been using TOTU bluetooth headhones just fine. Then, the computer connects to my device, but the sound still comes out of the computer speakers, and not my headphones. I have also tried to connect to a bluetooth speaker with similar results.
I have been searching for any updates or solutions, but I haven't found any.

I obtained a Acer Chromebook 11 C740-C4PE from a garage sale. Obviously it's a refugee from some school that discarded old class units to upgrade the school's classroom puters. When I turned it on I got a log in password screen which I couldn't use so I looked for web solutions to wipe or reinstall the OS. Also tried different things (like recover, reset, etc) but it seems I may have "bricked" the SSD according to some terms I see on the web. So now I have a SSD that's still alive and I can actually connect to my home network, but can't enroll into the school org with an email password. Tried using the Google account option but that process tells me no Google account found with my account info. That's weird because I do have a Google account with name and email ID, but evidently it can't be found. Why? So what to do? Buy another 16gb SSD? Tried surfing for one to plug into this Chromebook but it does not seem to be available anywhere for some reason. School enterprise issues again? Maybe I should just chuck this Chromebook but it would be a shame based on reviews I've seen. Any suggestions? Anyone?
This Chromebook is quite possibly the most frustrating thing I've ever bought. Throwing aside the fact that the trackpad stopped working after a few days (which I assume is tied to a disconnection within the case), the internet continuously disconnects and, more frustratingly, won't reconnect without a restart.
I notice it when I try to save a project or load a website. The bottom icon will show that wifi is not connected. I click the icon and reselect the network. The wifi icon will then change to show as connected but nothing will load. Interestingly, if I try to load a page (such as CNN.com), the status in the lower right-hand corner of the window suggests (to me) that it's loading some data (e.g. it will tell me it's loading... I don't know... cookies? I don't know anything about this stuff but it will show something along the lines of "loading cdn.[text].com/").
Anyway, it will eventually pause on the of the updates regardless of the website. When I open my network settings, it still shows as connected. It's only when I enter settings that it shows it's not connected and only after this point does my wifi icon go blank/zero bars (as opposed to showing an 'x'). No matter what I do, I cannot get connectivity without restarting and losing my work.

Our brand new Chromebook crashed. Did the Google Recovery USB thing and within 2 seconds of reboot, the message comes up "an unexpected error occurred" and references the Google Chrome OS Recovery URL, which is where the crash message sent me.
Tried the USB three times. Repeated the entire process all three times from scratch.
Should I just take it back to the store (Best Buy)? It's only two weeks since we bought it.
