Satellite A300-1MC - screen is buzzing

My old Satellite A300 of 3 months has suddenly developed a buzz, it seems to come from the middle of the right part of the screen and also right down, what could be the cause and how to stop it?

If I put my hand on the screen it will improve the buzz and also buy to move the screen slightly.

Can someone give me some advice?

That doesn't look too good. You must send the laptop to a Service Center authorized to repair as soon as possible.

  • Satellite A300-1MC PSAG8E - Win 7 will forge index

    PO10220 BIOS update reduced WEI

    Hello

    I have Toshiba Satellite A300 1MC (PSAG8E) 5.
    To improve performance there a few weeks, that the Vista Home Premium has been replaced by Windows 7 Home Premium.
    Until it doesn't index performance Windows was 3.7, but after installation, it has been reduced to 3.2.

    That's why & what can do?

    In my desperation I found on the Web of Toshiba site that PO10220 the BIOS update would improve performance.
    There is a warning window of the unknown publisher that I have downloaded the update.

    The result was that WEI has been reduced to 3.0 (which are pretty low).

    Why is he past & what can I do?

    Hello

    You have changed the operating system from vista to Win 7.
    The two systems are different and so the Windows experience index is different
    This is nothing unusual.

    In Windows 7, the maximum score is 7.9 (and 5.9 for Windows Vista users).
    While these numbers may seem strange to those used to a scale of 1 to 10, the Windows team has established the numbers for a reason.
    As technology becomes more sophisticated, the index will extend to 8.9 or beyond, to accommodate the faster hardware.

    More details about the Windows experience index located on the Microsoft page!

  • Satellite A300 - 1MC PSAG8E - software of Toshiba Assist application password

    Hi all

    I just bought a Satellite A300 - 1MC (model No. PSAG8E-00W00TEN) and I am using the software Toshiba Assist, but its me asks for a password and I don't know what it is or where I can find it.

    Any suggestions?

    Also slightly off topic, the laptop contains buttons to control media player, is there anyway I can change to control iTunes?

    See you soon
    Ian

    Have you tried to do an update of Toshiba Assist? A new version and all the other stuff from Toshiba which you can find here:
    http://EU.computers.Toshiba-Europe.com
    Maybe the update will solve the problem.

    On command buttons, I think you need to configure iTunes as standard Media Player and select all the files to iTunes playlist.

  • Satellite A300-1MC (PSAG8E) - get Bluetooth to work

    Hello

    I just bought a toshiba satellite a300-1mc and cannot get the bluetooth to work on it. ???

    The box says it has built in bluetooth, but even when I reinstall the bluetooth stack he will not recognize the built-in bluetooth device, it just says: connect a bluetooth device and press ok or cancel the installation? I can't take this wise because it only picks up the built-in bluetooth device?

    I checked the hardware Manager and can not still find something to do with bluetooth

    Any help would be very appreciated that I could really do with the bluetooth on my laptop.

    The box say it has bluetooth, it's why I can't work on why I can't make it work

    I'm not sure that if I deleted something... when I first got this laptop, it took about 5 minutes to start so I disabled a startup programs load... but I do not remember stop bluetooth... and I checked to see if I disabled something.

    HELP me please lol

    Rolex is right. I ve checked the specifications specification and Satellite A300-1MC is delivered without BT module. :(

  • Satellite A300-1MC - I have bad discs?

    I recently bought the upgrade to Windows 7, which has just arrived.

    I know that there are some things that I use which will be like everything does not work with Windows 7 so I did a dual boot, two reasons one is if I can still use the Vista operating system and the other so I can get used to Windows 7 and its different ways before going over to him completely.

    The problem I have is that if the disc of Windows 7 seems to have loaded OK Toshiba upgrade disc with all the system files like DVD, mouse, touch programmable keys key etc. does not load as she asked my model type and the number, but they are not in the list that appears.
    I have a Satellite A300-1MC.

    Only, I bought the upgrade when I went on the site of Toshiba and informed the option to update the page. I also tried my laptop more old, but who told me that it was not covered by the offer so the disk that I should work with the laptop more recent (A300).
    Have I been sent the disc wrong or is there something I need to do to get it to load?

    I really want to keep the dual boot, but if there is no way to make Windows 7 work then I have my money on another asted product from Ms.

    Hey Buddy,

    I'm a little confused about your Mr. ad if I understand you correctly Yes your problem is just that you can t find your model (A300-1MC) on the upgrade disc.
    Is this correct?

    If yes I can only say from my own experience that you should look for the model number. AFAIK A300-1MC belongs to the series of PSAG8E and you will get this model.
    Check this box!

    I hope I could help a bit and if you have any other questions, please let us know! :)

  • Satellite A300-1MC - WLan is not working - no network controller

    Just bought Satellite A300-1MC.
    It does not recognize Netgear wireless network (even with 'walk' "and switch alt F8 active), or a BT HomeHub network (is not 'see' their at all).

    To check device manager... can not see that there is no installed... wireless driver no wireless card doesn't seem to be listed. (Network controller has a yellow exclaim question). Network card installed is REALTEK RTL8102E PCI... which I think takes care of the wired ethernet connection).

    Any ideas how to get operating a wi - fi connection? (I have "worked around" the issue of a Wi - Fi connection using a card spare provided by NetGear USB, but I would get the internal card to work.)

    Should I have the software for the network controller? If so, what & where I get it? Or a driver for the card Wi - Fi internal? If yes what is it and where to get them?

    Any help much appreciated.

    Thank you very much

    John H

    Hello

    Well, I think you mixed with something.
    The LAN card is Realtek but the WLan card comes from Intel!

    So if you wifi card doesn't work I recommend that you download the WLan driver from this page:
    http://195.182.196.33/WLAN/?page=downloads

    Here you choose the Intel PRO/Wireless 3945/4965/5100/5300 driver that should work for sure.

    Good bye

  • Satellite A300 - black screen after long race

    I have Toshiba Satellite A300 1 portable PC series since 2008.

    It worked fine until the last few days. 2 days back when I started, it works fine until I go to bed (about 4-5 hours).
    "" I put my computer on and I slept, when I woke up in the morning, seen the button works / stop light is lit, "plugged in", "lit", "battery" all the lights are on but black screen of the tower.

    I moved the mouse, you press the mouse, press the SPACEBAR, enter keys on the keyboard, but nothing of this fact the live screen.
    I checked the fan works and the machine is hot normally.

    I noticed the CPU/HDD LED does not blink, the fact does not illuminate.

    The day before yesterday was also even, but after that restart was again very well.
    yesterday also repeated the same thing.
    Today also repeated the same thing.

    Please note my power saving mode: hip - turn off monitor - 1 minutes, turn the HARD drive - never.

    This setting is for last 2-3 years and normally off the monitor used to live on the movement of the mouse / key pressing.

    Can someone please help me figure out why my screen goes black after a night or more running morning.

    Thanks in advance

    Generally screen should turn off, but the laptop must continue to work.
    It is not easy to tell what happened.
    Can happen that laptop did restart because of a windows update installation?
    Some applications are active during the night? Some download or something similar?

  • RAM is not detected on my Satellite A300-1MC

    Hello

    I bought 4 GB of memory RAM upgrade Pro and it does not seem to detect it on my A300-1MC

    Here is the link for the RAM I got where it is evil, but I doubt it because the part number matches what I need:
    [http://www.memoryupgrade.pro/4gb-toshiba-satellite-a300-st4505-memory-1x-4gb-pa3670u-1m4g-pc2-6400-ddr2-800mhz-so-dimm-upgrade.html]

    Any ideas what I need to do?

    I have a 3 GB already installed and I took out the 1 GB and put 4 GB in its place - the BIOS didn't detect it as I know that 32-bit Windows usually use all the 6 GB.

    Thanks in advance for any help on this.
    If you need more simply make information let me know.

    Thank you
    Keith

    These problems are typical, when someone buys a product or incompatible products name.
    My advice is to return and buy compatible and tested modules of RAM. What you need is 4 GB DDR2 - 800 MHz module, with PA3670U-1M4G part number. It seems that the RAM you bought must be right, but... What is the brand of this module?

    Best brand for the Rams is KINGSTON.
    Check it out on KTT800D2 / 4G.

    Is RAM recognized if you use only this new RAM (slot A)?

    By the way: your Satellite can be improved up to 8 GB of RAM. Cool!!!
