Charging of noise and the LCD

Hello

I have a T400 and I have 3 small question:

1. whenever I plug in the charger, it makes a beep noise loud... y at - there a way to disable this feature? it becomes bothersome in the library when all of a sudden, it gets

2. is it possible to tell if my screen is a CCFL or LED? I bought my computer laptop off a gentleman on craigs... but its nine, never open with warranty. So I don't know if its LED or not.

3. makes the screen on the T400? Computer of mine was made 09/09 if that helps.

Thank you!

1. go in your bios under config-> alarm, you can turn off the beeps by disabling them.

2 download everest and it should tell you the p/n of your screen, then google the p/n and it should tell you if it is LED or CCFL.

3 Everest should tell you that it is usually LG or Samsung...

  • Tecra S1: Notebook generates noise when the LCD display is on

    Tecra S1 is 4 years old and generates a high noise when the LCD is turned on (from last week). The noise comes most of the keyboard. Could this be a defunct ups?

    Is there an easy way to fix it? It's not very loud, but in a quiet that is audible.

    Hmmm I think this noise comes certainly from the FL inverter.
    But I can't tell if the inverter is faulty or not because I noticed that her top on different laptops when the brightness of the display is placed on the lower floor.

    But if you think that this problem was not present in the past, then you need to contact a technician who could help you replace the inverter FL.

    Dear members,

    I broke the touchscreen for my Acer V5 - 122P when the laptop has fallen. I'm trying to find out how I can have it replaced. How much should I order? The LCD works but the touch screen is not. The touch screen and LCD are separated? Alternatively, they are integrated? I'm not a computer person, so please excuse my ignorance.

  • Laptop warns constantly bad hardware Insertion/withdrawal with the noise and the icon

    My laptop uses repeatedly insert/remove hardware alert when I did nothing. The Windows materiel.wav audio file is played and immediately followed by a materiel.wav Windows. In this case completely randomly and when making external hardware usb. Alerts are becoming increasingly common and is accompanied by appearing and disappearing immediately remove device icon.

    I disabled the sounds related to insertion and removal of hardware and sounds have disappeared, but the icon blinks always upward. This can only mean that the computer detects incorrectly insertion/deletion of material.

    Anyone know what this might be or how to fix?

    Thank you

    Hey Karena R,.

    Thank you for your help. I worked on that it's actually a problem of material in this particular brand of laptop Dell. I did things you suggested and used Device Manager to uninstall the USB etc. root hubs, and in doing so I noticed a mistake in the MMC disk section. The icon and the alerts flashing to the top has momentarily said MMC device.

    I checked online and found that the MMC device or the memory on this particular laptop card reader is at the front under the touchpad, that the sensors for the memory card are inadvertently set off by the movement and pressure on the keyboard itself. The sensors have been in contact with the "Virgin" card that comes with the laptop to go out when not to use a memory card. So why the sensors seem to not notice and then immediately realize he is not a real map.

    Thanks for your help, and if you see someone having this problem again, I suggest to correct errors on the device of the MMC or removing the blank card. I removed and I have not had the problem since.

    Hello

    You must contact the Asus technical support to get the updated BIOS updated. Once that is done, try to install the necessary drivers and check the status.

    Note: Changing the BIOS / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  • Uninstalled Codec IDT now no noise and the mixer opens up to black screen

    Codec IDT - original title

    When uninstalling unnecessary programs, I accidentally uninstalled the IDT audio codec, and now you hear no sound. Even when you click on the speaker icon and the helmet on the taskbar, the mixing table does not appear, just a black screen. Is anyway to fix this? How can I return the audio?

    Most often when a device does not work, it is because the driver is damaged. Re-install a new copy should help

  • Satellite P20-771 with Windows 7: no noise and the screen turns white

    Hi all.. I installed Windows 7 Ultimate on this machine. I tried the latest Realtek AC97 drivers, install the driver and everything seems fine but no sound is produced at all. Regarding the graphics card, I used a few modded Nvidia Drivers 97.tel xx I found at Guru 3D... There is no way to activate AERO, the pc hangs if I try.
    I put the system to turn off the screen after 10 minutes of no use... it becomes white instead. How do I? Any clue? Also, does anyone know if there are any modded driver that can run AERO? All the ones I tried did not work.

    > any way to activate AERO
    P20 is an oldie and I guess that the hardware specifications are not good enough to run Aero!
    It was the same keys with Vista installed on old notebooks.

    On the Microsoft page, you can find some info what equipment is needed to use Aero.

  • Once connected to VPN, no noise and the display returns to Legacy Version

    Hello

    I'm having a problem with my Windows XP Home Edition lose an output audio and returning to its display go back to a previous version.

    Scenario:
    -J' have VPN connect to my network to work and then remote desktop for my work machine.
    -After the closure of the Office remotely and disconnect the VPN, I no longer hear any sound. YouTube, WMP, Rhapsody and system sounds don't work anymore.

    Scenario:
    -Possibly associated with VPN/remote desktop as well
    -The taskbar menus / deform slightly and return to the old regime. It looks like in Windows 95/98/2000 when looking at the screen.
    -I do not know what causes this, but usually not noticed after being there for a while, long enough for the screensaver to be launched on.

    What I tried:
    -Scenario 1: unplug my speakers to the machine, by searching for driver errors in the Control Panel, looking for driver updates, turning the speakers off tension.
    -Workaround solution: restart Machine

    -Scenario 2: nothing

    ~ 3 months ago, I had an infection, which I thought that I solved it with Malwarebytes or Avast. Other FREE antivirus/anti(fill in) suggestions?

    I recently did a full system scan with Avast, Malwarebytes and a registry cleaner.

    Thank you

    Hi DaveCavaceci,

    Your question of Windows is more complex than what is generally answered in the Microsoft Answers forums, that you are connected to the virtual private network. It is better suited for the IT Pro TechNet public.

  • Satellite L650D - LCD noise in the background

    Hello!

    Please tell me there is someone knows solution or tool that will synchronize the LCD?
    I have a noise on my LCD screen which is very irritating, is the strongest on a gray background.
    On a white background (or other light colors) is ok. I can work normally, but sometimes it's tiring just my eyes when I'm working on gray themes or something.

    Looks simular like noise on my screen on PC. I solve that by pressing the button on monitor auto config, but I have no button here :)
    Help, please!

    Hello

    To be honest, I never heard about the noise from the LCD screen.
    Are you sure that this background noise is caused by the LCD and not another part such as mainboard or AC adapter / CC?

    In any case, you must follow the instructions posted by Akuma. Check the display settings and update the BIOS.

  • C1765 done yellow toner a printer roller noise rattling and the printer does not work

    Hear a clicking noise when printing.  Replaced the yellow toner and the rattling is still strong and the printer will not work.  The noise and the vibration felt on the new toner only occurs with the yellow toner.  What is happening, is the printer goes wrong.  "low density, yellow to replace the cartridge, printer restart" I just put in a new cartridge.

    Hello David,.

    Please post on the forum. According to the information you provided, it looks like you have a mechanical failure within the printer itself. This device is more compact and carriers Dell limited parts, the best option at this stage would be to replace the printer. It is the course of action we would take if the product is under warranty.

    Kind regards
