Satellite 1800-514-display is off every few seconds

Yesterday, I have a Toshiba Satellite S1800-514. I have install the OS (Windows XP Home) again.
Laptop screen turns off every few seconds. When I press the small button above the power switch (sensor for portable fence) there is a beep and the screen wakes up again.
Same procedure again after a few seconds (5-50 sec).

Is there someone who can explain what happened and how to fix this?
The problem exists in all modes (Setup/bios dialogue, BACK, starting of WinXP, running current WinXP command prompt).

Thank you!


It's not easy to say what is causing the problem, it could be the inverter FL, chip graphic, LCD display...

In your case, you should first test an external monitor. If the external monitor doesn't work properly, it s a problem with the graphics chip or motherboard. If the monitor does not work this is a problem of the FL inverter or LCD.

Good bye

    It's very strange that you can not start the unit at all. In this case it is probably a hardware problem (beep).

  • Cannot install Windows 2000 on my Satellite 1800-514

    I am trying to install windows on my Satellite 1800-514. but when Setup tries to copy files to the hard drive I have some errors on some files are not copied correctly (it says it can't find them, I checked well and they are on the cd).

    is not always, but often the same files. jump results in an unnecessary installation (cannot start). It is the first time ever I am trying to format and reinstall windows on this laptop. I tried gentoo (linux) for a few days and it seems to work very well (except it's me mistakes sometimes when starting from cd)

    so far I have tried:
    -Another cd (all seem to give me the same problem, they worked on all the others I've used them on front of the pc...)
    -windows XP pro cd, gave me an error of not being able to load a file (looks like the installation of 2000?)
    -have you memtest86 to check memory, he finds no errors, also I tried to install with just 1 of my 2-bands memory, that has not helped either. so I don't think that memory is the problem.
    -do you have a chkdsk /R from the recovery console to check the hard disk for errors, no have been found...

    I'm naïve, what to do/try then?


    Reset you HARD drive after using the Linux operating system? If please do it properly and then try to install Windows using the recovery CD.

    If the error again please contact the Service partner. In my opinion there must be a missing file.

  • Satellite 1800-514: need parts such as keyboard, screen, inverter

    I have a portable Satellite 1800-514, I need to get some parts of second hand for this that I have a few internet size for parts, but I need to know what other laptop I can take parts to repair it.
    These are the parts that I need of keyboard, screen, inverter and the front of the case where the screen is.


    If you are looking for second hand parts then I would recommend the search on Ebay for a Satellite 1800-514 of second-hand sites.
    Especially a full section of second hand is much less expensive than individual parts and devices!

    In my opinion, you can use the entire Satellite 1800 series parts.
    The screen, keyboard, FL inverter and the screen frame must be the same.

    In addition, if you want you can contact Toshiba service provider in your country.
    Guys might provide a list of compatible parts and devices


  • Satellite A135-S4666 - cooling fan turns on and turns off every 20 seconds


    I'm from the Argentina... I just bought a new Satellite A135-S4666 and I noticed that the cooling fan turns on and turns off every 20 seconds.
    It is a little annoying and it disctracts me of what I'm doing... is there a solution?

    Thank you very much.

    Hi Martin,

    This behavior is perfectly normal and nothing to worry about. If you find the noise irritating cooling fans you are likely to change their behavior by using the utility of Toshiba power where you should be able to set the cooling mode to run more quietly. I think trhe default is to allow the CPU to run at full speed, which will, of course, the fans turn every few seconds, but by reducing the speed of the CPU, the heat produced will be lower and therefore the fans will run less often.

    Kind regards

  • Recovery from sleep - Satellite 1800-514

    I'm developing an application on a Satellite 1800-514. Here's the problem: is it possible to turn on the laptop in sleep mode without pressing the power button (for example, by pressing a key on the external keyboard to PS2, or by moving an external mouse)?

    Thanks for any help!


    You should know that if the Toshiba power saver is installed on the unit the Microsoft power management doesn't work. In addition the energy saver is responsible for standby and hibernation mode.
    Here, you can set different parameters.

    Well, I can't say much about your developed application. I think that if you want to use you own tool, so you should remove the energy saver. But you know all the tools and the 3rd party applications, you can use at your own risk.

    PS: I'll be a happy man if someone here in the forum will give you a precise answer.
    It is a forum for users with currents and issues problems and not an application developer.

  • Cannot find drivers for Satellite 1800-514


    I just installed Windows 2000 on my satellite 1800-514 because with Windows XP, it's so horrible slow and I hope that goes better with win2000.

    then I tried to install the drivers of my cd but then after restarting, I got a blue screen. so I guess that the pilots were not compatible with Windows 2000.
    im looking for the correct drivers, but in the section download toshiba is now no Posibility to select the 1800 series. So where can I get them.



    Please check a little better all the options before you write something absolute here. Everything you need you can find on the download page of Toshiba under

    Please note that Satellite 1800 is old enough laptop model, and you should search under Satellite-Archive first choose Archive under product type.

    All that s!

  • Satellite 1800-514 - reboot with puppy linux 431

    Hello, I installed puppy 431 and 412 (frugal HD) on a Toshiba Satellite 1800-514 with processor celeron 1 ghz, 256 MB of ram and 15 GB HD.
    When I try to restart it just hangs in a black screen, but does not restart. If I want to stop, no problem.
    Windows XP restarts correctly.

    could someone help me please?

    p. s.
    I have updated the bios with the latest version, but makes no difference
    I tried several versions of linux, but all have the same problem (puppy 412, eccentric 1.1, pup214rc5).

    I tried everything I was advised to do in linux forums, they think it's something related to bios... 5021bed2078a398b0

    Hi abarnabe,

    If Windows XP starts correctly, the problem is related to your Linux distribution. What does s and there is no hardware malfunction.

    As you know I hope, Toshiba doesn't supports Linux distributions. This means that you have to look for a solution yourself, and here the most users use Windows. So I think you should ask the Linux professionals.

    Here's a helpful article:

  • Satellite 1800-514: I can put 60 GB HARD drive

    can I put a 60 GB HDD in a satellite 1800-514

    AFAIK you can certainly use the 2.5 s of 10 GB, 20 GB or 30 GB HARD drive but I m not 100% sure if BIOS will recognize the size of 60 GB.
    I searched a bit for certain part numbers: HDD2151B, HDD2157G, HDD2154B, HDD2159B

  • Satellite 1800-514: D - link G650 + PCMCIA card - cannot install drivers

    I finally decided to add wireless to my old Satellite 1800-514, but when I try to install the card, reports of windows that my drive does not contain the correct driver. I downloaded the latest drivers from the website of Dlink but I get exactly the same error, is this model of incompatible card with the machine?

    I was originally under XP Pro SP2, but I went down to XP SP1 incase it was an SP2 issue, but nothing did.


    I don t think that there is a problem with the device.
    I studied a bit on the net and found information about the pilot.
    It seems that users have problems with d-link driver that was downloaded from the d-link website. The driver on the CD supplied with the PCMCIA card should work properly.
    But if there is no if you need to contact d-link support.

  • iPhone 6s freezes every few seconds on iOS 9.3

    On iOS 9.3, 6 s iphone, the phone will freeze every few seconds in ANY application.  When it thaws (after 3 to 10 seconds), all entries with the touch screen, the home and lock buttons will be running very quickly.

    I tried the following:

    -soft reset

    -hard reset

    -Turning off the night shift

    -activate airplane mode

    -cleaning and restoration from backup

    -downgrade iOS 9.2.1 (seems remedy) and back to iOS 9.3 (back problem)

    It's extremely unusable because typing seems frozen, then a bunch of letters appears when it thaws, pressing the buttons for locking/unlocking inadvertently takes screenshots because it saves that kept pressed buttons, apps are impossible to use, and scroll of sites and application will freeze and then jump down/up.

    See if you can do a reset... it can help him freeze.

    Tap settings > general > reset > reset all settings

    Then, restart your iPhone to test.

  • Screen refreshes every few seconds

    Computer model: HP Pavilion e040us 17

    Product: EOJ89UA #ABA

    Windows 8 (not 8.1)

    My wife left her cell open and when she came back, she was asleep.  She tried it to wake up (hit the wrong key), got frustrated and held down the power button to turn off.  She doesn't think that updates have been applied since the screen was black

    Now, once it is started, it can use one of the applications 'tiled' who do not use the desktop computer.  Once the office is open, the screen refreshes every few seconds.  The entire desktop goes blue, the desktop icons and background image disappear, and everything disappears from the system tray.  The system tray starts to rebuilds with the battery indicator, indicator of network, "speaker" icon, date & time, then all the rest of the system tray is back with the office (background image and all the icons).  In about 1 or 2 seconds, the cycle starts all over again.  I left the laptop that works thinking that something just needs to work to stand, but two hours later, it was still there.

    If I press the windows key enough times, he swaps ends up back in the tile view, and then he begins to paint it too.  The screen goes blue and then everything comes back.

    While this is the case, the only way to get the stop menu is ctrl + alt + delete.  Moving the mouse to the bottom right of the screen to bring up the menu of the settings does not work because the screen refreshes faster that you can click on the settings button.

    I restart the computer in safe mode and it didn't happen.

    I'm stumpped and really need help!


    Hi, Mark.
    I don't know if this will help, but for me, I used system refresh to restore my laptop to factory settings (but keep my documents) and the problem seemed to go away. Partially, I think it was because I was running Classic Shell for Windows 8.0 rather my 8.1 - Although may not be the problem, refresh the laptop seemed to work!
