I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

Are you getting any lights or activity at all? Do you see the charging light come on when you plug in the AC Adapter?
Could you try holding down ESC and the Refresh Key (like F3) and then hitting the power button?

Yes, the repair was covered by the warranty!!  I contacted the manufacturer, they started a repair ticket, I shipped it to Acer for repair and within 2 weeks (maybe less) it was shipped back and fixed!  It is still working perfectly and I am very happy with my Chromebook.  Call Acer and carefully follow their shipping instructions to return it for them to repair.

I have an Acer Chromebook 15 which works well and I love it.  However, the text on the screen shows up all weird. Text will be overwritten by other text, all smashed together, etc. I have set and reset the text size in settings. I can resolve the issue by using control + or - to resize the screen and that usually stretches every thing out so it looks good, but still there will be some items of text overwriting other text. It is kind of annoying to have to size and resize each screen, every time I go to a new screen. My Chrome OS is up to date and I have had no other problems with the laptop. What am I (or the Chromebook) doing wrong?

Also the screen can't rotate at all, no matter what I do.. Anyone know how to fix these two problems? edit: nevermind, it just suddenly started working

I'm fixing a Acer Chromebook 15 Monitor Screen. When I boot up..the background is very dark and I have to use my phone flashlight to see that its been fully booted up. So I thought it was the screen that needs replacement. So I just replaced the monitor screen and its giving me the same thing, very dark. Do you think its the connection that needs to be replaced. By the way I did a full reinstallation of the operating system, so everything is brand new on boot up. Any suggestions what needs to be done to get this fixed. Thanks in advanced.

After restarting chromebook for update, it would get stuck on a black screen.  The power light would be on as well as the other one.  It took me a while to figure out how to get out of screen.  If i pushed the power button while holding escape and refresh button, it would take me to an external boot screen.  I then had to press the power button to restart my system.  I figured out why it does this as well.  It will do this only when i am using my T.V. as a monitor through my hdmi port and the chromebook is closed.  I guess it figures that it is off and messes up the update process.  I sent a message to google support and wanted to post here as well because i do not know which service would be responsible for the fix.  I was wondering if anyone knows if this issue is being worked on because i only use my T.V. as my monitor while i am at home, therefore this can be very annoying.

Well, I accidentally dropped my laptop...on my foot no less. The screen worked for some time afterwards, however started to flicker and just recently went completely black. I took the screen apart and saw no damage. The screen is NOT cracked or damaged in anyway. I can shine a flashlight on the screen and see my desktop just fine. Now when I open the lid, it will stay on for just a few seconds, but goes black. The problem? I'm confused. Is there a part for the screen that I can simply replace? or do I have to buy a completely new screen? It seems like a waste since my screen isn't cracked or damaged, just the back light is gone. There is no inverter in this model so that is not the issue, it is all LED. I'd appreciate any feasible answers to resolve this issue. Thanks in advance

I had a previous thread about the same problem back in May of this year about my screen going black. I replaced the screen with a new one and everything seemed to be fine until a few days ago. Opened lid and screen was gone. So far I've done basic troubleshooting to try and figure out what the problem was. Last time I was able to connect a monitor to the laptop and use it, this time that isn't working. I've drained the power supply by removing the battery & plug holding power for 30sec and trying to restart. I've also checked the memory this time, removed old and put in a new set, still nothing. The diagnosis I've come up with is that it may be the video card which I know is integrated onto the motherboard. One thing I did notice is that it's taking a while for the fan to pick up and come back on and it came on when I closed the lid. It does not shutdown now when the lid is closed. Sorry for such a long description of the problem, I just wanted to be as detailed as possible and get some kind of feedback as to what this might be. Thank you

Just bought a Dell Inspiron 15 5000 and after just a couple of days I noticed that the screen has some odd black spots/shadows at the bottom. I guess I did not notice them before because the Windows bar was covering them.
I have the same problem even when the laptop is booting or in bios, so doesn? seem like a OS problem.
Are all 5000 Series laptops like this? Is this something standard for this laptop? Now that I noticed them I find them very very annoying.

Hi,I bought a Dell Inspiron 15 7000 Series laptop around about November time last year, and after a BIOS update a couple months ago or so it now will randomly go to a black screen, but the backlight is still on. The BIOS update being near the time that this began to happen may be a coincidence, but it was the only real change during this period.On this black screen, I have no cursor and none of the buttons on my keyboard do anything. The only solution I've found is to hold in the power button to shut the whole system down. 
There doesn't seem to be a particular pattern as to when this problem occurs, it will just randomly go black.
This has happened around about 6/7 times in the past few months. All the events did occur late at night though (past midnight). However, this could just be because I usually sit on my laptop longer at night time, and therefore that increases the chances of it happening.
Due to many "Black Screen Crashing" problems with Windows 10 - that aren't the same as my problem - a google search did not help. 
System Specs are as follows: 
System Model Inspiron 7559
OS Name Microsoft Windows 10 Home
Processor Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz, 2601 Mhz, 4 Core(s), 8 Logical Processor(s)
BIOS Mode UEFI
Ram - 8GB
Graphics Card - GeForce GTX 960m

I turn on my laptop and the dell logo pops up and it just goes to a black screen with only my cursor being visible. The other day it was working just fine, then later on the fan starts getting really loud and I turn it off and turn it back on. This is when my nightmare starts, I turn it back on and stays on the dell logo and says "diagnosing your pc". The fan is still running loud, then after a few hours trying to get it work, the fan just stops making noise altogether. I run the system diagnostics and it says my fan and hard drive won't respond. I open up my laptop to what's internally wrong with the fan and hard drive. All I see is the fan doesn't spin, but after several minutes it starts to. I don't see why it says my hard drive won't respond when I fully inspected it and there was no visible damage whatsoever. I put everything back together and keep trying and which it being in the current result that is stated in the beginning. Only thing not mentioned is that the fan is just struggling to spin at a constant rpm. In the diagnostics even though the fan is somewhat spinning, it still indicates the fan and hard drive are unresponsive. This the worst thing for me right now because I'm looking for a job and start college soon.

The fact that you were able to boot normally after F2 into the bios menu, F9 to re-set the bios to factory default, then F10 to save this default bios setting, ***strongly*** suggests that the bios was losing it's memory of the specific hard drive that was installed.    Jack E/NJ

I have a black screen on my Acer Apire 4552 Laptop. I am fairly good at fixing computer problems, but this has me stumped? This is what I have done so far:

1. Took off the battery and held down the power button for 2min, then plugged the power back in without the battery and nothing happened. tried this also with holding down the F8 and also again holding down the f10 button. Nothing.

2. I thought it was the hard drive , so I had bought a new one and put it in and hit F10 and my computer started to boot up! So I decided to put my old hard drive back in and by chance it came on and started to boot up also. I was very happy and I used the computer for 1 day with my power cord plugged in, but when I unplugged it and went to plug it back in later and use it again it was back to the dreaded Black screen!

3. As suggested, I took my computer back apart and pulled out the both RAM memory cards and cleaned them and tried switching them in each others slot as suggested and re-booted the computer multiple times, but to no avail. Still nothing?

4. Another thing I notice: My battery had gone bad a year ago and I bought another one and had been using it fine, but it does get much much hotter than my old one as it runs. So I don't know if it is shutting down over that or not? I put it in the freezer for 15min as suggested by others and tryed turning it on again, but still nothing!

ANY SUGGESTIONS??? IT WOULD BE GREATLY APPRECIATED

Most desktop monitors, when inactive for periods of time(usually preset in o.s. or altered for individual tastes) saves electricity by powering down the monitor, and let it "sleep", but any programs running on the cpu, continue on, unabated.

You could increase the time before your hard drive turns off. I have one for my wirless adapter with maximum performance down to low. Your lan may be listed if your not wireless. A combination of increasing the hdd time and lan may get you around the problem.

Sounds like its either the LCD screen or the inverter or the backlight in the lcd screen.

Either way its a fairly easy fix since you just replace them.

Since its a 14" screen from what I could find, your looking at the $100 Range for a new LCD not including installation or an inverter if you need it.
