My Laptop takes very long time to start(black screen sleep/power on)

hi , my laptop toshiba satellite p875-s7310 started to take very long time to start or wake up from sleep , it just shows a black screen (no toshiba logo, no windows logo nothing just black screen).
when i press the power button the processor works fine, the harddisk seems like restarting(the fan keep making little noise just like when u open the laptop for first time and keep repeating it).
it takes minimum of 20 mins to start and sometimes over 1 hour, so what is causing the problem and how i can fix it? thanks

  1. Have you tried reloading the operating system. If it is an issue related to the operating system, this will reset it to the default.
  2. Another option is to flash the BIOS.

    What is the exact model of the system (laptop?)? What is the exact problem that you are having?

    im a using an emachines(acer) desktop and im having pretty much the same problem
  6. But what is the model number?

    To update the BIOS, you need the model number, serial number, and the operating system.

    Then go to the manufacturer website and select the latest update BIOS for that model. Then follow the instructions in the manual concerning updating the BIOS.

    If necessary, you can also download the manual from the same site.

    Here is a basic view of "clearing CMOS". It resets the BIOS to the default settings.

  9. thank u sooo much
  10. ok so after i clear my CMOS then what??
  11. Instead of starting in the middle, tell me exactly what you system is doing. What is the exact system components. What power supply, graphics card, CPU, motherboard ? If you don't know that information, what is the computer model, serial number?
  12. I have exactly the same problem. Did you find any solutions? Thank you very much in advance.
  13. This is an old thread. You should open a new thread. You can PM me with the thread.

    Usually if your system is taking a really long time (assuming no hardware issues) to start up Windows there is a problem with the BIOS or the actual startup of Windows.

    For the BIOS, clearing the CMOS can help. Just make sure you write down the important stuff like drive priority list so the computer will know where to find the operating system. plus things like fan settings that are pertinent to your particular system. If that doesn't cure the problem, you can try flashing the BIOS to the most current one for your motherboard.

    If it is Windows that is slowing things down, ,you probably have too many programs in your startup list. You can run MSCONFIG and under the startup menu, you can remove (uncheck enable) to the programs that you don't use often. Note this isn't removing the program, it will just take a bit longer to load when you use it.
