Satellite M40x - 184 question on screen

Hello I recently noticed that when I use normal mode or long-term my noteboook screen make a quiet noise
and I want to ask you guys what is normal.

Thank you very much

Hi Tom

It's normal, and you can hear it just enough ambient calm. I noticed the same thing on my Tecra. I'm not a technician but I think the supply voltage must be reduced by an electronic part and it produces that sound.

If the brightness of the LCD screen is set to the maximum level the sound disappears.

  • Satellite M40X-184 road's DVD/CD-RW cannot read CD

    It is possible that your drive is broken.
    These problems usually occur because the lens of the player is unable to calibrate correctly.
    Well, your laptop is not very old the guarantee must be valid. In this case, I recommend to ask the service partner to help him. The guarantee must cover all replacements.

  • Audio does not work on Satellite M40X-184

    Hello

    N Malgas Johannesburg South Africa here.

    I picked up a virus on my Satellite M40X-184 that weaken my audio device drivers.
    Relaoded Windows XP Home Edition and Audio devices still does not.
    Looking for a way to reload the drivers.

    Any help would be appreciated.

    Hello

    I think in the first place, you should check in Device Manager if no yellow exclamation point is visible. This could help you know whether or not the audio driver has been installed correctly.

    You will find the page of the Toshiba Realtek driver audio v5.10.00.5740.-T
    You must first uncompress it before starting the installation. You can perform the installation of the audio driver also from Device Manager

    After installing the driver of its success, you should look in the audio and audio devices. This option is located in the control panel.

    Check if the "secret" was not enabled and go through the unique volume controls and set it to a higher level.

    Good luck

  • Satellite M40X 184: is my HDD ok?

    Hello I have a Toshiba Satellite M40X 184

    When no program is running my hard drive works from time to time make boring of the loud noise from time to time its not but I am curious to know is - this normal?
    could someone tell me

    Hi Tom,

    If you are running Windows XP, then it's quite normal that your hard drive show activity from time to time. You will have several active processes running that will periodically access the hard disk.

    You can also have background tasks that will periodically throw in life and cause a disk access activity.

    Kind regards

    1. is it possible to put a new drive (faster and longer)
    2. is it possible without losing the warranty
    3. what discs do you offer me

    Thanks Szczepaan

    It seems that the device must be capable of supporting hard drives 2.5 "up to 120 GB. Additional cell phone supports DMA synchronous Ultra100.

  • Satellite M40 184 - Question on battery and speakers

    Hello everyone.

    A few months ago, I bought a laptop (M40-184), which uses the harman Kardon speakers. I have two questions to ask you.

    1. the battery does not work for more than 1 hour (when the laptop is any more, or when internet explore is enabled). There are no other programs running. I think that this is not normal. What can I do? I'll be back there?

    2. speakers are a strange low frequency noise, when I'm listening to music or watching DVDs. It doen not to be little heavy or something. It was supposed to be a very good pair of speakes.
    What can I do?

    Thanks in advance

    Hello

    Usually battery working time depends on the use of the laptop.
    If you use a high performance such as 3d graphics tools tools, games or watch DVDs battery working time goes down.
    But if you only use the explore IE the battery should work more than 1 hour. In this case I think that it s a battery failure. If you need to contact the ASP for the replacement of the battery.
    In addition you must always remove the battery from the unit if the power adapter is plugged.

    2.) as far as I know that the Toshiba Virtual sound utility is preinstalled on his unit. Here, you can change some sound settings. Maybe you can solve the problem with the speakers.

    Best regards

  • Satellite M40x-149 - Question about RAM upgrade

    Currently, I have 512 MB of RAM and want to upgrade. The jury of the RAM has two screws, should I take this and replace it with an upgrade of RAM, or leave the original in and put the new in the slot on top?

    Thank you.

    Hi RareOz,

    The amount of RAM you want after upgrade?
    If you want a maximum of 1 GB of RAM for example, you can leave the original RAM in and buy 512 MB additional RAM.

    But as far as I know M40x supports up to 2 GB of RAM, and that's why it would be necessary to install the module of RAM of 1 GB in each slot. That's why you need two new modules.

    The specification is PC2700 SO - DIMM DDR - RAM.

  • Satellite M40X-184: problem with keyboard - only writes a character in 1 second

    Hello

    There is an interesting problem with my laptop, it cams with Xp Home edition with 1 partition, I used partition magic to create another and then format C:, after installation of XP Pro. Install drivers one by one, now when I try to write something in anywhere like msn, notepad or Word, she wrote just a character in 1 second;

    Like when I write "trial" he write in 5 seconds... Why what happened and above all how can I work this?

    Hello

    have you tried to uninstall the pilot how you installed? Maybe you should do this, I think it's probably just a software problem and no hardware failure.
    So you can also try to set the rate of your keyboard type in Control Panel-> keyboard control-> (delay repeat, repeat rate) and maybe it s just there a setting that needs to be corrected.

  • LCD screen turns off without reason - Satellite M40X

    I have a problem with my laptop Satellite M40X, I work when the LCD turn off and I hear two PIF. To turn on the LCD screen I need to restart the laptop, but the problem persists after a few minutes.

    Can someone help me, please.

    Hello

    Here you can compare the version of the BIOS installed on the laptop with the one published on the page of the Toshiba driver.
    If you use the older BIOS, you can try to update. Maybe the update will sort this strange behavior.

    But there could also be a hardware malfunction if the BIOS update does not help.

  • Satellite M40X Screen Display problem

    My Satellite M40X has a black vertical line which occupies 20% of the screen on the left side. The rest of the screen shows a full view. Change the display settings makes no difference, and there is no mention of this error in the manual. You don't know whether a problem with the LCD screen or a problem with the adapter and drivers. Wanted to check if someone has experienced something similar and can advise you.

    Hello

    Check using an external monitor.

    If the same vertical line would be seen on the external monitor, an internal graphics card problem may be possible
