Laptop Screen turning on and off

Q: Laptop Screen turning on and off

I'm using a lenovo G40-80 laptop running in windows 10 OS. My laptop's screen have been turning on and off all for a while. I could still see the running applications but I cant use my keyboard because it looks like it is ghost-typing. The volume and brightness is appearing alternately on the screen like it's being pressed at the same time then the screen would turn off then turn back on after seconds and sometimes even a minute.

Preferred Solution: Laptop Screen turning on and off

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.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


A few days ago, I dropped my laptop from less than 12 inches over the carpet. It landed on its corner. Since then, the screen won't turn on. There is no physical damage to the screen or the casing. There have been a couple of times where I was able to get it to turn on by using a paper clip to press the reset button or holding shift and f8 while I press the power button. Neither of these solutions work the first time. When I am able to get it to turn on, the screen looks perfectly fine. There are no visible problems with the colors. The only other problem related is that the backlit keyboard won't turn off when the laptop is closed. The computer works fine otherwise.

After leaving my Toshiba Satellite running on my bed on a particularly hot day last summer, the screen won't boot up when I turn it on. The screen remains off while the power lights, fan, drive, all seem to power on and run.

I have tried rebooting it by removing the battery and then turning it on again but it still doesn't work. I'm really looking for someone who can guide me through some troubleshooting so I can figure out what's wrong.

*edit* I forgot to mention I have also tried plugging in other screens and it does not boot up on them either.

Hello BambooforPanda,

It is possible that something fried in the heat, can you tell us the exact model of Toshiba Satellite you have so we can do some research, some examples here

When you tried this did you press down the Fn and F5 keys at the same time to toggle between displays.

When I turn the laptop on the power light comes on as does the wifi light but the screen doesn't. It's like the laptop doesn't know the lid is open. Similarly when I shut the lid it doesn't shut the laptop down/put it to sleep.I can also turn caps lock on and off etc.I would just like a way that I can access the info on the laptop such as photos etc.I have also tried plugging a vga cable in but have been unable to get a signal to the other screen.Any help would be greatly appreciated.Thanks.

so my friends computer started acting weirdly a few days ago. When power is turned on, the screen stays black and cd reader makes a weird sound (check the video and make sure you have volume turned up)
I'm not sure what is causing this but if I am able to repair it at home it would be great.

I have a Hp Pavilion dv4 2145dx Everything was fine one night, and I shut it down and unplugged the AC adapter. The next day, I plugged it in, turned it on. I heard it booting and the lights were going on as if it were turning on regularly but there was nothing on the screen, it was just completely black, no lights or anything. I looked on the keyboard and the lights next to Caps Lock and Scroll (Num Lock) were flashing every 2-3 Seconds. I researched the dilemma to see if there were similar cases which have been resolved, so following one of them, I plugged in an external montior to see if the main components were working and as I plugged it in the screen turned on! So I knew that the screen wasn't "fried" from overheating or anything of that sort. Everything was fine again, then I guess the AC adapter got lose, so the battery went down and shut the computer off. I plugged it back in and the same problem occured, so I tried plugging the external monitor in once again and this time nothing happened, the external monitor didn't even detect the laptop anymore. The powerlight on the external monitor that would normally be green if plugged in and working had turned yellow, however when I would unplug the laptop the external monitor would say NO SIGNAL, but when I plugged it back in, nothing would be on the screen and the light would turn yellow again. I tried removing the battery and AC Adapter and held down the power button for 30-60 seconds to do a power res...

Hey there this is my first post here.

So I turned my laptop on as usual to an unexpected black screen and a frozen cursor at the top left. Nothing came on the screen prior. I then tried turning the machine off via the power button to no success so I had to pull the battery.

Now it no longer turns on at all! I've tried discharging it too and nothing

I have a semi-new (destroyed) Acer aspire 5310 notebook. I took it apart, (the motherboard was down) and now I have a CPU (still connected, don't know can I do anything with it, if yes tell me) an optical drive, a hard-drive two speakers and an LCD. What I want is tu turn the LCD into an external LCD witch I can connect to anoter computer.

If it'll cost alot, I'll just buy a new screen for 100 and forget about the laptop.

I understand it'll take alot of work and I'm up for that.

The LCD has four wires coming out of it. One has a quite wide connector (pics if needed) coming from the left side of the screen. There are two small black and white wires, one coming from each side, which connect to a small circuit board, which has a wide connecting thing at the end, then theres one small wire which has a very narrow connector (two bit) and nothing else.

I'll give pics if needed and I'd really like some help.

I have a Compaq V3000 that has been working pretty well until I installed Windows Vista about 6 months ago. Then it started shutting off all the time randomly like 5 minutes after I would turn it on and I got that to stop. Then randomly I came home and my computer screen was black and I turned it off and took the battery out; however, the lights on the keypad stayed on...even the power light. Then when I took out the power cord and put it back it the lights turned off. Finally, after several tries, I got my computer to turn on all the way. Then I turned it back off that night and the next morning it would not turn back on. I have been working on it for over a week now and still get the same outcome. Here's exactly what happens:

I turn my computer on...then the Compaq startup screen comes up...then the screen goes black and when I try to hit F10 or F8, a real fast message comes and goes...it's hard to even read...but it says "Operating system not found." It did this before I got it to turn on that last time too...but then I got it to turn on. But now I just keep getting the same outcome. I got the F10 page to come up one time and I was told that my harddrive looked like it was going bad but they couldn't tell for sure.

Please help! : )

A:Compaq laptop screen goes blank after turning on

Well I see two possible solutions. A. OS problem or B. your HDD is going bad.

So what i would recommend is if you have a old HDD laying around use it and try reinstalling your os on it. if it works then your HDD is probably bad so purchase a new one.

Do you have any external harddrives hooked up to your system?

Answer me about the external first before proceeding

Is it worth turning off the Toshiba logos / splash screens that crop up before Windows 7 loads? I have been looking around to learn how to turn the off but have yet to find an answer I'm confident in!

If it is, where can I learn how to do it?

A:Solved: Turning off splash screen on Toshiba laptop

You may be able to turn it off in the BIOS but it's rarely an option in laptops, but is it worth it...nope, it won't improve performance. I'm sure someone has found a way to flash a hacked BIOS onto some machines but I'd strongly advise against that as you could end up bricking the laptop.

This morning, my laptop seemed to be working fine. I was on it for about half an hour but once I got home, and waited a few hours before using it, I went to turn it on and all it displays is a gray screen. This gray screen is smooth at first, but slowly deteriorates to a display such as this: Laptop Display Example  I really can't do anything else because this screen appears right after startup, and blocks me from using it any other way. If you look close to the deterioated screen, you can see tiny dots of different color. Buttons such as the wifi button, brightness levels, and the capslock still function. The screen will brighten or darken, and the lights on the other two keys turn on and off normally when clicked.  This upsets me because I have only had this laptop for about two years, the warranty is finished, and I've had so many issues with this laptop from the software to problems with Windows 8. I didn't do anything to damage the screen, and no one comes into my room who could have damaged it.  Also, I have tried removing the battery and removing the charger ( which it can't run more than 10 minutes without ) and letting it cool down, but when I turn the laptop back on, I recieve the same response. My laptop is an HP b011nr, at least that's what it says after 'model' on the bottom of my laptop. Bear with me, I'm not much of a computer person.

I'm not sure if this is in the right area or not.

I had my laptop on and running fine for a few hours accumulatively (because I did put it in sleep mode ocasionally) last night and then one time I turned it off and when I turned it back on it lit up but nothing came up on the screen.

I turned it back off by holding down the power button and decided to let it cool down. Later I turned it back on and it was working fine seemingly and then it would "turn off" because the screen went black but the lights were still on. Then it would refuse to turn on for a while. I let it set overnight and I turned it on and it seemed to work again but then it did that thing I mentioned where the screen goes black but the lights are still on and it won't turn back on now. Well, it will turn on because the lights will be on but nothing will show on the screen.

I also think there might be a chance there is a virus on it. My alert keeps popping up and telling me that there is but it says it's quarantined and infected or something. I don't really know how to explain it.

Hey all,
So I am writing on behalf of my mother.  Her laptop (HP Pavillion dv4 circa 2009, running on Windows Vista) won't start up properly.  Upon pressing the power button, the screen goes immediately to white.  No mouse, no HP or Window welcome screen, nothing.  I've tried turning it off and back on (multiple times), Ctrl+Alt+Del, and pressing the F8, F10, and F11 buttons (the ones I read were most likely to take me to the safe start/reboot mode) upon start up, but to no avail.  This happened for the first time today, she came home from work and started her computer and it did this.  She thinks the last she used it for was Facebook and online banking, the night before.  I don't know what else to do as thoe are the only key combinations I could find, and her screen will not display anything but pure white.
Can anyone help me?  I will try to get more information if you need it, but as I can't get the computer to start, it may be somewhat limited. 
Thank you so much in advance!

Hi everyone,

From last few weeks I'm having this strange and annoying blank screen of death. I could just see a blank screen (not a blue screen) while either waking up computer from sleep or while trying to turn on the display by moving cursor/typing something(waking up from power saver mode of display, I set display to be of after few minutes of inactivity). So essentially screen becomes total blank. Just once or twice I saw this BSOD "DRIVER POWER STATE FAILURE" but for all other times my screen is just blank. I could see the Hard Disk activity LED on during this blank screen. And almost after all subsequent boots, I could see "Windows has recovered from unexpected shutdown/serious error - Check for solution" message.

Dear all, Happy new year and all

I wonder if you could help...

My husbands laptop this evening will not turn on AT ALL. It was working perfectly well a few days ago:

When the power button is turned on all that happens is the power light turns green. There is no sound coming from the hard drive (the hard drive light doesn't even show). In addition, there doesn't seem to be a fan working. And finally, there is a light strange noise (not a hard drive noise).

I am wondering whether it is a motherboard issue????
Woud creating a recovery bios boot CD help? Would like wipe the hard drive?

The major problem is that the laptop is used for all our business transactions and GASP.... we haven't backed it up, so we could potentially lose very important data
Many thanks and I do hope somebody is out there to help us.

I have a Dell Inspiron 15r 5520

It all started last Friday when the dreaded "Plugged in, not charging" happened. Little by little I had the laptop plugged in and eventually the computer just failed to work. I opened it up and pulled out the Ac/dc power jack and low and behold a port wire is broken, so I replaced it.

I also tried to turn it on after that, then I found out the Power Button was broken, so I replaced that.

After replacing all of that the Laptop refuses to turn on. 
I do have a charger on the way and now I'm wandering: Should I have the charger plugged into the computer while I wait for the other one to show up, or should I keep it in and attempt to charge my battery?

My lights for anything will not turn on at all, so I'm also wandering if the motherboard is dead? It would be a shame if it is since I just purchased a replacement last summer.

1. Charger stopped charging and became a plugged in not charging
2. Replaced Power Button and broken Ac/dc powerjack 
3. Computer fails to turn on 
4. No lights down at the 4 light panels even when charger is plugged in.

Thank you in advance if you are able to assist me in this issue.

I shut down my laptop yesterday. It won't start today. If I plug in the charger the charging light I glowing but when I switch on the power button nothing happens. I tried the hard reboot method. Removing the battery and charger holding the power button for 20 seconds and then if I plug in just the charger(adapter) then there is no charging light and the laptop still not switching on. I also tried NOVI button it's just displaying Lenovo and getting switched off. Kindly help me as soon as possible. Thank you

I went to open my laptop yesterday (it was plugged in overnight) and it notified me the battery was nearly empty and then the computer turned off. I unplugged it, plugged it back in & turned it on again but it still told me the battery needing charging.I went to do the same again and now it will not turn on since last night. I have tried the hard restart (unplug the power supply, take out the battery, hold the power button in for 30+ seconds, plug in the power supply again & press the power button) but it will not work & every time I press the power button the hole where the power supply connects to the laptop blinks 3 times.Help - I'm supposed to be doing summer school & now can't do anything!!!

I turn my laptop off in the evening (Usualy to Hibernate). I get up in the morning and its off. I get home in the afternoon and its on. Now this has happened a lot. Its realy easy to tell when computers on or off as the TV tuner has a big bright blue light.

Now either i have a ghost or my laptop is turning itself on some time during the day.

Hi there, I have a HP Pavillion g series (Pavillion g6) computer running windows 7. Recently, my laptop has started turning itself off when it is not plugged in. The battery is still usually at about 30 - 40% (or so the battery icon tells me) when it turns itself off completly.  It completly turns off and when I try to restart it it starts the black screen with the 'start in safe mode' or 'start windows normally' etc options. It's really beginning to frustrate me and I've poured through google and these forums to see if I can find something that might help but thus far, nothing. Any help greatfully recieved.
