Satellite A25-S279 - RTC error, but F1 key does nothing.

The error I get:

"RTC * battery is low or CMOS checksum is inconsistent."

Press F1 to set Date/time. »

I have read many similar topics with the same problem, but with mine, I can't enter the BIOS if I press the F1 key. Is it normal when occurs the error above? I thought enter the BIOS was not dependent on the RTC battery. Currently, I have the laptop turned on and thinking of leaving at least 8 hours, as many people have said. However, having no answer by pressing the F1 key concerns me.

Thank you.

Hello

Please check you user manual. I put t know what chapter but check the battery info.
The same mistake has been mentioned in my user manual and here the solution is very simple;
You must charge the battery of the CCF. This battery provides power to the motherboard.

You charge the battery for 12-18 hours. Leave the laptop connected to the power supply during this period.

To set the time and date, you need to access the BIOS. I think you click everything first ESC then F1 to access in the BIOS settings. Try it.

Good bye

  • Satellite A25-S279: how to reinstall XP with Ghost DVD without disc internal

    I have tosbhia satellite a25-s279 and toshiba dvd of ghost.
    My internal dvd drive is broken (w / some difficult, it can play some audio cd of some of the time. it recognizes no cd-rom or dvd). I also have external pioneer dvd writer dvr-s606 (connect to the satellite via USB). I want to reinstall xp.

    The Bios is 1.10, the chipset is ALi M1672 rev 0. You have the option to boot from HDD, floppy, CD-ROM, and LAN drive.
    I think that you also have the option of bootin off pc card, but is not in the Bios.

    It seems (from reading these forums) that my satellite does not support boot from the external drive, so I can't use the ghost disc?

    I found another Web site, which suggests to make bootable USB drive and load xp from the memory stick.
    However, read these forums, it seems, also, that's not possible with my satellite?

    I suppose I can buy a replacement internal dvd drive, but these seem very unreliable, and I already have functioning external drive.

    any other advice would be appreciated.
    Thank you.

    > It seems (from reading these forums) that my satellite does not support boot from the external drive, so I can't use the ghost disc?
    That is right. The external USB CD/DVD drive is not bootable, and you will not be able to boot from the CD

    > I found another website, suggesting to make bootable USB drive and load Xp from the memory stick
    No, it is not possible to boot from the USB key. BIOS does not support this start option

    I think the only way is to buy a hard drive taken in internal load and then boot from the CD.
    You can also try to boot from the local network, but it's not easy and you will need a RIS server.
    I think that this is not really a solution.

  • Satellite A25-S279: restore without a recovery CD?

    What is the appropriate way to restore a computer without a recovery cd? It has a XP code in the background, and that's all I have. The laptop is: A25-S279.

    Thank you.

    Well... you have certainly a Win XP OS.
    If you n t have the Toshiba Recovery CD then you can order it from the ASP in your country.

    In other cases you can try to reinstall the OS Win since the original CD of Microsoft. Please note that the key which is placed at the bottom of the laptop doesn t work with other versions of Windows XP and the CDs.

    Therefore, buy an original CD of Win XP.

    Then you can download and reinstall the XP drivers from the Toshiba page us because this laptop is designed only for the American market.

  • I have windows vista but CD Key does not work so that was ok until now

    The President complied,

    I have the authentic drive of Microsoft Windows Vista, but now the product key does not work as it was working before and I use it for the past two years. Mr President, I am facing a very big problem my windows stops automatically after 30 days, please fix this.

    Hello ElumBuneri,

    As you stipulate that Windows stops working within 30 days, I'll assume that you have been unable to activate your copy of Windows. You receive the error message probably is "key to product already in use"? If this is the case, a simple phone call will solve the problem.

  • CC of Photoshop for PC - ctrl-alt-arrow key does nothing

    I installed Photoshop CC on a new PC, and the combination of keys ctrl-alt-arrow does nothing. He used to reduce the area of framing around pixels and move the selection by 1 pixel. Now, it does nothing. Using shift-ctrl-alt-arrow shrinks the selection around the pixel rectangle and move the selection of 10 pixels, meaning that it is supposed to do. Any help is appreciated.

    I got this in Windows 7 with my driver Intel HD 4000 as well. Enabling auto-start for the Intel Graphics Control panel was the problem. He caught in the trap of the combination of keys Ctrl-Alt arrow, but not the Shift-Ctrl-Alt-arrow key combination.

    If the solution is simple http://superuser.com/questions/796396/how-to-disable-igfxhk-module-process-from-starting-u p-with-windows

    I just went into msconfig > Services tab, deselected "Intel HD Graphics Control Panel Service" and restarted the PC.

    You will always have access to the graphical control panel, but Ctrl-Alt-arrow is no longer blocked in Photoshop.

  • Satellite A25-S279 - Cant Boot From USB Drive

    Hello everyone. I'm new here.

    Is there anyway that I can boot from a hard disk on the A25 USB? In any case to update the BIOS to give me the option to boot from USB hard drive?

    I already went through the BIOS and used the HWsetup nothing helps.

    I want to run Linux on a mini-usb HDD, I just picked up, but I can't seem to boot from the USB connection.

    Please let me know.

    Hello

    You on the right, the BIOS supports a boot from the USB FDD.
    BUT it is not possible to boot from the USB HARD drive or USB key

    The BIOS offers these startup options:
    HDD, CD/DVD, LAN or USB FDD

  • Satellite A25-S279 - screen is too bright all of a sudden

    I went to the MS site for cleartype fonts and fooled. I did not like the cleartype fonts, so I manually turn off in windows and internet explore.

    However, something happened that is causing the entire screen to be very bright makes all the washed out colors. I plugged in the VGA output for a CRT monitor, and brightness/colors are there.

    My keyboard has been broken for a while, so I use an external USB keyboard, which means that I can not access the FN key. I did to in in Windows display properties, but the sliders he for the Trident card which adjust brightness, saturation, and tint cannot be moved. Sound like they are there permenantly.

    Also, I went into the Bios and made sure he was using the default settings.

    Anything else I can try? Do not have the restore CD.

    Thank you.

    Possibly there s nothing wrong with the brightness setting.
    You said that you don't like the cleartype fonts and have disabled manually in windows and internet explore.
    Perhaps this is a reason to deliver you

    Have you tried to put the BONE to this early time?
    I mean the point of time before you turn off cleartype fonts?

    I think that you should do this to make sure that this option screen brightness doesn t affect.

  • Satellite A500 - switch WLAN and the FN keys does not turn the wireless

    I have currently problems try to activate the connection Wireless on my laptop. My laptop model is a satellite A500 PSAR9A O2J001. My laptop's physical wireless switch does not work and neither my Fn keys don't work (none of my function keys work not at all). It was awhile I saw an orange light next to my mobile switch indicating it was on, but one day, it's just off. Since then, I was not able to reactivate it after a lot of searching on Google, and this place is my last resort after doing so many things.

    Any help or comments would be appreciated, I am very desperate to solve this problem for studies.

    Your description is OK but rather general isn't easy to say with certainty what the problem is here.
    Is the card properly installed wireless (Device Manager)?
    FN keys work in general? You can use other keys FN + Fx? You see flash cards when you press the FN key? If so what options you see when you use FN + F8 (WLAN I think)?

    When you move position WLAN communication works and use the FN + F8 to what exactly happens?

  • Satellite Pro A-153 C50: F11 function key does not work

    The F11 key where I can spend the sound power switch does not work!
    The other keys work correctly.

    Everyone knows how to restore its function?

    Hello

    You use the special function or Standard F1 - F12?
    The special mode of operation allows you to use special features without pressing the FN key.
    This means that if the special function mode, you must press only F11 to turn the sound on and off. In the case of special function mode is off, you must press FN + F11 to turn the sound on and off.

    You can enable or disable the special function mode in:
    Office-> Office help (in the task bar)-> tools & utilities-> function key

    But I wonder if the F11 key works with other software?
    For example: pressing F11 key while using the Internet browser (internet explore) should allow mode full-screen. You can check this?

    Keyboard F11 key is maybe defective and so the sound ON / Off function does not work

  • Satellite A110-178: no sound, but default OS does sound work

    The sound card seems to have become selective in what it plays.

    Default windows sounds work. Dxdiagnosis sounds work as well
    When I tried to use the assistance of Toshiba to test sound, it did not work. Other sounds (music/games) do not work either.

    System Restore is not no longer works (don't know why).

    I tried to reinstall the drivers, but it didn't work...

    All solutions?

    Hello

    What sound card appears in Device Manager?
    Are there any yellow exclamation marks?
    If this isn't the case then all devices work properly and the drivers are installed.

    Have you used the image of Toshiba preinstalled or have you installed the OS manually from the Microsoft CD?
    If you manually installed the OS form Microsoft's CD so it would be very interesting to know if the same error with the image of Toshiba.

    What option did you use in the assistance of Toshiba?
    AFAIK you can test audio only with the tool of diagnosis of Toshiba in the assistance of Toshiba.
