My laptop is an Aspire V3-571-6447 with windows 8.1 os.For the past month or so it starts beeping and then the screen goes dim and then it beeps and brightens up again. This might go on for 3 or 4 minutes and then it stops. Is this an indication of a problem? It doesn't seem normal to me and from what research I have done it seems that beeping is not a good thing.

 dim and brighten....sometimes as frequently as every 20 seconds. happens when im not plugged in!

View 4 Replies View RelatedI had to order a replacement screen to replace the original one which cracked after being stepped on by my boyfriend. The computer still worked then though if plugged in through an external monitor (like VGA or HDMI), but since I replaced the screen, even that won't work. I might have severely messed up by being impatient and forgetting to take the battery out before replacing screens. After I replaced them, realized my mistake, and took the battery out and put it back in again, it still wouldn't get past the problem: When I turn it on, charging or not, the power light and sleep mode light blink very slowly (blue), and the laptop beeps every ten seconds or so. The screen won't turn on at all either, even if plugged into an external source. I've tried it with and without the battery in and it hasn't turned on either. After further research of the problem, the most promising thing seemed to be reinstalling the BIOS (google "Acer Dead Screen Problem"), and I downloaded it off Acer's website and tried running it via flash drive as all the tutorials wanted me to. Nothing happened. The only difference from the tutorial is there's supposed to be an executable file with the BIOS download, but it wasn't in the folder.

View 5 Replies View RelatedWhenever I unplug my laptop from external power, the screen considerably dims and the taskbar turns white over it's usual blueish black. I've gone into the power settings and changed them so that brightness is 100% when unplugged, but to no avail. According to my computer it's at maximum brightness when unplugged but it's obviously not. Trying to increase the brightness by the sun key or pressing Fn up doesn't work either. Tried to go into BIOS via F2 but couldn't find a video or brightness option.

Bright usable screen on mains power but when the power lead is removed the screen goes so dim you can hardly see it.Battery indicator shows fully charged. No difference when fn and f10 or f9 used.
My x220 is driving me crazy these days. Some days ago I experienced very strange behavior of my system. I was just using the notebook as always as it started to stutter.
With stuttering I mean everything is working for 1-2 seconds then is stuck for 1-2 seconds, working, stuck, working so on so forth.
With everything I mean the mouse movement, hard disk load, graphics movement, audio, everything simultaneously. This problem does show up not only if Windows is up but also when Windows is booting or if I start a live linux distribution.
I also noticed that sometimes when I'm moving around the ultranav trackpoint the cursor jumps to one display edge and opens a context window as if I had pressed the right mouse button.
Â
What I did so far:
Reboot my system several times.
Checked Task-Manager: nothing out of the ordinary
Reset BIOS to factory settings
Updated everything to newest stuff
Started a live Linux distribution instead of Windows 7
Decrypted my system (TrueCrypt)
Deactivated Power Management/SpeedStep via BIOS settings
Switched to Single-Core processing via BIOS settings
Swapping RAM from 2x8GB CORSAIR to 2x4GB KINGSTON
Swapped SSD with original HDD
Try booting windows in safe mode
I'm almost at a point to say this can't be a software issue and that it is something mainboard/CPU/GPU related, but I want to be certain before contacting the support.
Another thing I noticed: The stuttering starts exactly when the windows logo shows up and the screen automatically dimmes itself while starting windows. Something is happening in that moment. I may need to add that I did not install anything prior to the current situation. That does support the hardware relation.

My Son has an Acer Travelmate 7510.
It beeps three times (1 long, 2 short) on start up and nothing shows on the screen. We've plugged a seperate monitor into it and that just shows all white.
I've just recently bought my acer aspire e1-570g notebook, and it makes a short single beep at random times. Sometimes it does't occure for hours, and sometimes it happens twice in a minute.I've already checked the Ram, CPU, GPU, Hard Drive with tester programs, even reseated the ram, but the beep didn't disappear.

I have the InsydeH20 bios. Â Any beep codes I can get ? I tried removing the memory 1 at a time, and same thing still happens.
The number keys on the right are locked and I cant use them. When I press the numlock key it just beeps and a pad lock open and shut on the screen.
I bought this laptop especially for these number keys.
My father’s notebook has been acting up for awhile. It beeps continuously at startup.
You would have to "F2" to the BIOS then exit the BIOS, then start up screen to come up again, beeps again repeat "F2" back to BIOS, but eventually XP would load. Unfortunately everything was sluggish, keyboard wouldn’t work right. So in my limited computer knowledge I decided to reformat the notebook. I could not find any back up disk that came with the notebook so I created a back up disk from factory settings via the Acer eRecovery Management process. I have ran this recovery disk twice. Both times I have installed the recovery disk I get NTLDR missing as well as the beeps have not gone away. From some online research beeps mean computer is telling us something is wrong with the hardware. Number of beeps tells what specifically; unfortunately I can’t find what continuous beeping means. NTLDR missing I found usually means that the computer is looking in the wrong place for the file.
I have no idea what I should do next to resolve the problem. Should I go out and buy an OME copy of XP Pro. Will friends XP Pro disks work as long as I use the XP Key found on the bottom of my laptop? How can i figure what hardware is causing the notebook to beep?
Ideally what I would like to achieve is a clean install with the most limited amount of Acer bloat ware installed. I am trying to find a list of what programs are needed and what programs are bloatware.
My T530 (a month old) is driving me crazy with this issue: Depending on which application is in the foreground, it will dim/undim the built-in screen (1600x900 version). I have turned off adaptive screen brightness in the power options, and I've turned off Film Mode Detection and Adaptive Contrast Enhancement in the Intel Graphics and Media Control Panel, but this "feature" won't go away.

How in the world can I get the screen to be on 100% brightness, unless I manually change it?
I'm using Aspire V5-473PG.

Recently I noticed that my touch screen sometimes starts to hits randomly at the bottom of the screen. This problem cause some windows became minimize and maximize on its own and when i'm watching video, the video keep pause, play and pause again. I tried to find any crack on the screen but found nothing.Â
I am very upset that my expensive Dell laptop has stopped working when it's less than 2 years old. When I turn it on it beeps 8 times and does this over and over Nothing comes up on screen just black? A friend said I need a new board thing as video card is on that.

View 2 Replies View RelatedJust two days ago I was using my laptop then turned it off like any other day. Later in the day I proceeded to turn it back on and received the dreadful 7 beeps with a blank screen. For the time that I've had it, I've taken good care of it, (never dropping it etc.) I have read on some of these forums that the 7 beeps could mean a bad motherboard/processor.

I've tried taking the battery out and hold the power button for 2 minutes. After that I tried holding D and the power button but there was to change. I tried an external monitor which did not work either. There are no beeps. It if I leave the laptop switched on for a few mins I hear the windows start up tune.

View 1 Replies View Related2 beeps I thought was a memory issue but the screen doesn't say anything about a memory problem. there are 3 options 1 boot to windows 2 boot options and the 3 I cant remember. option 2 and 3 may be out of order. I have looked in bios for memory test to turn it off but I don't see it. pressing F1 (first option) boots normally and system runs great as usual. 1 other thing, the battery light flashes red 4 times and then holds white for a second then cycles back to the flashing red. this all started at the same time. I tried to do a bios update but im already running the latest version so I get the window that says it wont be completed. the battery does seem to last a very long time as it usualy does, its a 9 cell battery.

View 3 Replies View Relatedmy laptop is not booting any more. Looks like everything turns on but all I get is a black screen and two beeps. If I press some keys I get the two beeps again.
Changed the mother board battery and RAM but no results.
sometimes when i boot up my laptop i hear 5 beeps and the screen stays black. computer doesnt boot just keeps doing that. Usually boots after turning it off and on after that. Also when it does boot up after having the beeping sequence the clock on my computer is reset.Â
This is from a brand new m14x rs laptop (alienware) that i just bought.
I've had a problem with my LCD for a while now. For around six months the screen sometimes turns black unless it is at a particular degree to the keyboard. For example, at 90 degrees there is a good chance that the screen will flicker and will mostly be black. More than 90 usually works.
Couple days ago I turned my laptop off and before it shut down left the room. When I came back after 15 minutes I heard the beeping sound. I turned the laptop off immediately. Â After that, every time I turn on laptop, nothing happens apart from beeping. I tried 'D' and then turn on. Also f12. Nothing changes, screen stays black. I also removed battery and pressed on turn on in order to get rid of excess charge.
Here's the issue:
On boot up, screen is black
Then 3 beeps follow
Then, I opened it up and  it became 7 beeps
I have been having issues lately with my Dell. Finally, one day, I tried to start it but it would only beep 8 times. It does nothing else, no screens, nothing. I need it for work.
