SCREEN FLICKERS WHEN I PLUG THE POWER CORD A/C

Can someone help me with this problem. My screen flickers when connected im playing games with my a/c power cord. Howerver when I remove the power cord, it works fine on battery. Also my battery almost won't charge at all with my laptop running, but when I put into hibernation or to stop it charges more quickly. Would appreciate any help as soon as POSSIBLE. Its a Dell Latitude E6400, windows 7

Diagnosis

The video "Refresh" is switching between 60 (on food) and 50 Hz (on battery), and the screen goes momentarily empty.

Solution

So what about current alternative, office > right click > properties > settings > advanced > monitor. Here, under the display settings, set the refresh rate of the screen at 50 Hertz. After you apply these settings, the flashing problem gets fixed.

    Computer: DELL Studio XPS 16

    I encountered this problem with my Pavilion DV6 after upgrade to W8 64 bit as well and is more annoying than it should be.  For what it's worth, I opened the AMD Vision Engine Control Center and disabled the "Vari-Bright" option on the power tab and which seemed difficult to get the error message every time my laptop is unplugged.  Does not solve the underlying problem and will decrease my time unplugged a bit, but I can live with that.

    Thanks for the steps, Amiarage.  Looks like we will have to just wait for ATI to fix.

    My laptop (presario CQ20-320TU) turn directly every time I plug the power cord without battery. What is the solution?

    Hi there @emonsonjaya,

    Welcome to the Forums of HP Support! It's a good place to find the help you need, so many other users, the HP experts and other members of the support staff.

    I understand that your notebook is turn on/off automatically when it is plugged. I'm happy to help you.

    I would recommend that you look at your BIOS, especially in power options and check if your BIOS has a setting option on automatically. If yes it change at your convenience.  Another option would be to update your BIOS and see if that solves it.

    Here is the page of support for your model and, if necessary, give it a try, it will automatically download the file if you click on the link. You then need to run the executable file of your current download folder.

    If you are having problems with an update of the BIOS, you can always restore it, using the following:

    I have a dell latitude E6500... problems with blue screen when I unplug the laptop.  his past about 5 out of 10 times now.  Ive updated all recommended microsoft updates and it is still the case?  is there a driver for xp needed to solve this problem?  It only happens when I unplug the power cord and it happens as soon as I unplug

    Hello suncoastsrq,

    Usually, when we see problems during shutdown, the cause is something that loads at startup.

    To this end, I would recommend mode startup minimum troubleshooting as seen in the following articles:

    http://support.Microsoft.com/kb/310353

    http://support.Microsoft.com/kb/316434

    Please note that after refine us the cause, it is important that we return to a normal startup and manually delete the startup program.

    In addition, if we can get downloaded discharge, the community has access to them and will probably be able to determine the cause.

    You can download the dump Auggy's previous suggestion?

    Let us know.

  • Satellite Pro U400 freezes sometimes when the power cord is plugged

    Hello! I know that this problem has been addressed here and there, but I'd like to open a new thread about it. Here's the scenario.

    I recently bought a new Toshiba Satellite Pro U400-247 (PSU45E) with two batteries: (a) the original, (b) in addition purchased authentic of Toshiba PA3636U-1BRL, 7200 mAh. The laptop has the latest BIOS (4.80) and the latest drivers downloaded from Toshiba and installed (ConfigFree is not installed). I use XP Pro SP3 (own installation by myself). Everything works fine, except for one thing:

    Sometimes (but), when the laptop is running on battery power and I plug in the power cord, everything hangs and I have to restart. A few observations:

    It tends to occur more frequently when the low battery alarm has rung;
    (b) it seems to happen more frequently with the 7200 mAh battery and less frequently with the original battery.
    (c) it seems to happen most often when a USB device (mouse, for example) has been linked to the laptop, but it is not a rule;
    (d) it seems to happen less often when I move the mouse USB at the time wherever I am connect the power cord.
    (e) I've experimented a lot with Toshiba PowerSaver settings (for example to change the levels of CPU for my profile) but nothing I changed seems to change the situation.
    (f) I tried different suggestions I found on various forums, but nothing works (for example the BIOS settings);
    (g) otherwise, I can say that I have not really seen a smoother computer, everything works really fine, no other problem :)

    Everything that makes me think it must be some sort of bug in the drivers of motherboard driver PowerSaver or other drivers interact with battery, CPU or possibly USB. Y at - it an explanation to this problem and can it be rectified in some way (for example, by providing a driver update)?

    Hello

    First of all, I never heard a driver from the motherboard.
    There is a drive chipset or a graphics card driver. There is no such thing as a driver of the motherboard!

    Look, man. laptop should work fine even the AC adapter is connected or not connected
    If the laptop freezes while there might be a software problem, but in my opinion it could be hardware problem
    You must reinstall the operating system if the laptop would freeze always the issue might be related to hardware

    First of all the memory modules and AC adapter must be verified.
    If the problem persists even using new modules and AC adapter, motherboard may be affected.

  • Notebook15-r110na Energy Saver: my laptop screen has suddenly started to go black when I need to plug the power adapter

    Laptop screen has just started to go black when I need to plug the power adapter to recharge, if I get screen back to normal.  I have not downloaded anything new recently.  I have download the free 10 Windows but that was months ago.  Any help would be appreciated, but please not too technical as I'm not an expert on computers.

    Maybe the powerplan battery is changed or not properly configured. You can see the current powerplan thanks the battery status bar icon.
    Please check if the powerplan options are correct.
    More specific:
    Brightness updates when it is plugged into the charger OK?

    Also: If the screen goes black, can still use you the shortcut keyboard keys to adjust the brightness?

  • T400s display flashes when the power cord disconnected - how to fix?

    Just got my T400s a few days previously and very happy with it!  But one thing that bothers me is when I unplug ac power chords, screen goes white, then back on. The same thing when I plug ac power chord back in.  I posted this question in another forum (NBR) and someone replied that this problem has disappeared after a clean install of the operating system without Thinkpad utils.  So, it has something to do with one of the utils.  BUT I can't find anywhere how to disable this behavior.  Please advice!

    Binaryspiral solution worked for me - thanks.

  • Satellite Pro L500 - stops when the power cord removed

    Toshiba Satellite Pro L500 stops when the power cord is removed even with the battery to 100%. I removed the battery and all the indications associated with battery answer correctly. For example turns off, Toshiba Health Monitor also indicates when the battery is removed. If installed Health monitor indicates that the battery is at 100%.

    Someone please help. I have not installed anything new.

    Hey,.

    For me, the matter is clear: the battery can't hold a charge so the laptop will be shut down because it has no power.

    I think you need to replace the battery with a new one and you can get a provider of service authorized in your country. Simply contact the guy and ask that they can tell you how much it would cost.

    You can find a list of all FSA here:

  • Two Macbook Pro, both does not start up, when I press the power button, I hear two disc bit Caryl, I see little light on the front on the displasy release button, black screen, no edge

    It was weird because I've NEVER had two computers have the same problem before. They are the model 2008 2.2 Ghz Core 2 Duo, 6 g of RAM, models of 128 GB of hard drive, the two Yosemite running, both had new hard drives, cables, batteries and RAM installed OWC (Apple approved reseller) and I use Macs for at least 20 years. In about a week, one just blacked out while sitting on my desk doing nothing, the other does the same on a week later. When I press the power button, I hear the drive hard hum twice, then all I get is the little light on the screen release button, that's all. Black screen. fails, nothing. I can press the power button and it will fit off the coast. Is it possible that some of them have infected somehow, or possibly send me the malware that has infected my system? I would not normally only, but for all of them to go down to one right after the other with the same problem just made me think, it must be the same cause, but what?  I had been in a war of fire recently with very ugly people, and I've never seen two Macs have the same exact problem in a row like that right.

    I took readers on the Macbook Pro, put them on sleds and threw them in my PowerMac, and both seemed fine, no problem, started well upward, ran utility disk on them, no problem, so I started to the checklist. Reset the PRAM. Nothing. SHIFT key at startup. Nothing. D at the start. Nothing. V order at startup. nothing. I wouldn't mind even their evisceration and making a portable useful with the parts of the two, but until I find out what the problem is, what can I do?

    If anyone has any suggestions, I would really appreciate it, I've supported every button I can think at the start, tried an inch USB key, boot and disk, this is the same Caryl bit both of the car, no chime, black screen, that's all.

    Thanks for your help.

    I don't think they are infected.

    The startup chime indicates that the Mac has made the initial diagnostic tests and there is no hardware problems or fundamental software.

    No edge in your case is a problem.  I think it's the luck of the draw to have 2 failures.

  • blue screen after pulling on the power cord

    I accidentally pulled the power cord while the computer was on, now I get a blue screen that says to run checkdisk, but I can't go beyong trhat screen.

    my suggestion is to start your computer with a xp cd and run a chkdsk command & via the recovery console fixboot.

    There is more info here but focus on option 2: http://support.microsoft.com/kb/314058

    Sometimes the fixmbr command must also be executed as well, if the computer gives you an error message later on "master boot record".
