Won't boot satellite A40-261 / No. BIOS

Hi all

I am currently trying to fix a laptop SA40-261 Toshiba to one of my friends.

He complained of the clock that kept resetting itself, because he uses it stationary because of a battery flat my first instinct was to replace the CMOS/RTC battery.
I have fixed a new battery for it and it has changed, but now the laptop no longer starts.

It turns on (power light), but there is no screen activity, no backlight, no disk, no activity of fan activity and no activity of audible alarm at all!

To try to reduce the factors of problem, I removed the card WiFi, the hard drive. Replaced the RAM and tried with the deleted frame (no screen, speakers, multimedia keys, etc.).

Has anyone here seen a situation like this?
Is it possible to reset the CMOS (if it could be blurred)?

Or this motherboard could be bricked?

> I set a new battery for it and it has changed, but now the laptop no longer starts
Well, seems that you damaged the motherboard.

> Is it possible to reset the CMOS (if it could be blurred)?
The CMOS battery is usually paid you could load the BIOS (CMOS) battery by connecting the computer laptop AC adapter for a longer period of time.
The main battery must be inserted and adapter must be connected. The laptop must be turned on to 18,20 hours.

But if the laptop can not be powered ON this procedure would not help you I really think that the motherboard is dead.

  • How to activate the resolution wide on external monitor on Satellite A40-261

    Hi all
    I have a Satellite A40 laptop and just bought an external display. I find only normal resolutions in the area of comprehensive property. Is it possible to expand the range of wide screen resolutions?

    Best regards, Leander

    Hello guys.

    First of all, I would like to say a few words on the screen resolutions.
    Mainly the resolution of certain is not available because the resolution is not listed in the graphics driver. In other words, if the driver doesn't support this resolution so you will not be able to choose.

    We try to look at a few:
    @BKV
    You have a Satellite M100. As you say that this laptop is equipped with an ATI card.
    Have you checked the settings in the ATI catalyst? Go to display properties and choose Advanced Options. Here, you choose the tab of ATI catalyst.

    New window should open, and you should see the ATU catalyst control center.
    Check the option display the Advanced view display. Check this area. Maybe the resolution is available here.

    @Lea
    This unit uses the graphics card Intel, but Intel tab should also appear in the advanced properties of the graphics card.
    If you n t found the right resolution, so I guess that the driver does not support!

  • Won't boot satellite L350D-212

    I put the hand on L350D-212 that won't start. By turning on the green power light turns on and fan start UM. There is no video on LCD screen or external monitor.
    I tried pretty much all the stuff I learned from this forum:
    (1) exchanged Rams
    (2) try with a different set of Rams
    3) took power, held down the power for one minute, then back button back
    (4) tried to hit FN + F5 to switch screens etc.
    5) tried to start without any installed memory

    All this led me esteem L350D motherboard must be replaced.

    The card mother n/p is V000148410. AGE (AMD)
    It seems that this particular Commission is hard to find, and those that are available is used as well.

    V000138440 motherboards are easier to find. Based on the quick image comparison, it seems that 138440 has just about size, shape and external connectors as 148410 - and it has socket AMD.
    According the description 138440, this motherboard is used in Toshiba Satellite L350 series laptop L305D
    Toshiba Satellite L305D-S5889 Satellite L305D-S5892 Satellite L305D-S5893 Satellite L305D-S5895 Satellite L305D-S5897 Satellite L305D-S5900 Satellite L305D-S5904 Satellite L305D-S5914 Satellite L305D-S59143 Satellite L305D-S5943.

    What would you - think would work instead of 148410 138440?

    GPU issues may prevent laptop boot

    > 138440 just about same size, shape and external connectors as 148410 - and it has socket AMD.
    So in this case the 138440 should also be compatible.

  • Won't boot satellite A110-178

    My Satellite laptop suddenly does not start after I recharged it.
    When I turn it on, the power light blue button as he always does. But then, nothing more. Fans CPU turns for a few seconds and stops. Nothing appears on the screen, no logo Toshiba or anything like that. The DVD player does not open even. It only turns off if you press the power button for 5 seconds.

    What this may be? Do laptops keep silent when the MESSAGE fails or they beep like personal computers 'normal' and is - it a different problem?

    Any help would be good. I tried to plug a second monitor, but it does nothing. Play with the battery and the power adapter (connection, disconnection) did nothing, so I think that's not the problem.

    Sorry James but I think there must be a serious hardware problem. If you are not able to see the BIOS settings or the Toshiba start screen I think it's time to contact the Service partner in your country.

    Please don't be crazy on me, but in your situation, you can't do anything that can help make your work laptop again.

  • Upgrade memory for [b] Satellite A40 - 261 [/ b]

    I want to upgrade the memory of my notebook.
    I know that the installed memory is DDR2700 (333 mhz) but I would like to know which brand is already installed and/or brands/types are approved by Toshiba.

    THX in advance

    Hello

    normally, you don't need to bother with the brands of MHz' are and stuff like that. If you point out that you want to buy (recommended) Toshiba memory original option for this model, nor a f.ex. use a 3rd Kingston memory advantage - you just say "I have this model, give me a 256, 512 memory or whatever."
    It will then work perfect in your system as well as the memory you already have.

    Hello

    I have been through the forum and not found a solution. Laptop start-up problems.
    L350D-213
    Win 7 32 bit

    A week ago I started having intermittent problems where the laptop wakes up not after going to sleep. I could normally solve this problem in power and restart. However, it has now to the point where I can't turn it on at all. The laptop starts, the fan starts to turn, the hard drive turns on but it goes no further. Nothing on the screen at all. I tried with a monitor and still nothing. If I have a USB mouse is plugged in when I turn it on the light on the background will flash briefly, then turns off

    I tried to turn it on by holding down the power button, I tried without battery. I disconnected the battery and the power cable and pressed the power button / stop for a minute. Still having the same problem. This eveningi tookl the laptop out and attempted to remove the cmos battery. He's stuck hard but I managed to remove it (out of one of the connectors in metal in the process. It is now set down). Nevertheless, the same povlem that happens. Anyone has any ideas or I'm going to buy a new motherboard?

    Thank you

    Hello Carlos

    For users of laptops, it is always recommended to use the drivers for computer laptop manufacturer and not designed the graphics card producer. As you can see there is no guarantee that it will work properly.

    The only solution is to install Toshiba a new.

    Hi moldovanvali,
    long story short - long said...
    -charge the battery fully
    -Start computer laptop game + time and date +.
    -Restart and load setup defaults + +.
    -change the boot for odd sequence +, + cdrom + or similar
    your system should now boot from the cd without pressing on + F12 +.

    If it does not start on cd/dvd maybe the optical disk drive is not able to start...
    There are many reasons for this...

    BTW: without entering a date and a time when the system starts only pressing on * F1 * (most cases)

    Hello

    My son satellite C50 won't boot to the top. It is connected to the power grid and will arrive at the password screen but as soon as you type goes into shutdown. Any suggestions please?

    Thanks in advance.

    You write about Windows or BIOS password?

    In any case, on this virtual path, it is not easy to give an exact explanation what can be wrong there.
    Your son of many important data stored on this machine? If this isn't the case, you should try to reinstall the OS and test it with the factory settings.

    What you can try is to enter the BIOS settings and leave the machine 5 minutes to see if cell phone will go OFF. If this isn't the case, set the BIOS to the default settings and try again.

    Is the cooling fan may be strong at the start of the machine?

    Hello...

    I'm on Toshiba Satellite A40-151 the DVD for this broken but this isn't worth it.
    The problem is that I can't enter the setup (BIOS) to boot from a different boot device, or I do not now how to enter.

    Help, please

    thanx

    Hello

    I think you have a Toshiba BIOS.
    In this case you must press the ESC key immediately after the laptop has been powered. Try to press the button several times

    By the way; You can also use the F12 key to get the boot menu.
    Then you could easily choose your boot device
    This also works
