Question about Computers & Internet

Need to remove the "top cover" of my Compaq Presario 12XL400 (actually a 12XL426)to get to the power on micro switch. I can remove the palmrest, keyboard, heat sink, cd-rom, 2 hinge covers - but I can't get the U shaped top cover to come free. Any ideas??? - would love a link to a "service manual" Thank You, Doug

    Thanks. There are a lot of tabs - but sequencing isn't the only issue.

    Is it necessary to remove the LCD before I can remove the top cover?



  • SLODoug Feb 19, 2008

    This is a laptop - Compaq Presario 12XL400 (actually a 12XL426) from about 2001.

    This unit has a hinge cover on the left and right hinge - and a center cover that may conceal a center hinge.

    It is the center cover that seems to be concealing screws that would release the top cover - and I cannot even tell if the center cover is part of the top cover or is removeable.

    Thanks Again,

    Hmmm...I'm still unclear. I don't want or need to disassemble the LCD. I may want to remove it - so I can get the top cover of the laptop off. The top cover I am referring to is a large plastic thin U shaped molded piece (about 13 inches across the U with two 6 inch legs of thin molded plastic making up the legs of the U.

    I need to remove the laptop top cover so that I can replace/repair the power-on microswitch.

    Thanks for giving this you good thinking.

That has a load of screws or tabs alongside the chassis, that you need to press(tabs) in sequence. be gentle, as those can snap off mighty easily.

    is this a desktop or a laptop?

  • Patrick Michaels
    Patrick Michaels Feb 19, 2008 that I'm clear on's not that hard..there is a little panel above the keyboard that comes out, and reveals the screws holding the lcd in place. keyboard MUST come out first though, to release the connector for lcd.

    then, there will be 2 or 4 screws in back or bottom of laptop, holding lcd to main part. remove those, set them aside safe.

    then, with a very gentle touch, and a super thin blade, starting at the place at the bottom(closest to you on the lcd) start the process of easing the bezel from the lcd. you may need to remove some bumpers from the front of the lcd, and remove some screws under them.

    then, there are a series of screws along the sides of the lcd..take them out..

    and then you are there.

    hope this is enough to close this account

    got it..those screws are under the unit, and need to be removed from the bottom. some of them may be an odd size, so keep them separate, ok?

Does it actually have a wireless network adapter? Check the network adapter settings. Does it show both LAN and wireless? If it does you may need to use one of the Function keys to launch the interface to turn on the wireless.

Freezes on the warm boot screen MC9000

This can be for a number of reasons.

First thing would be to try and cold boot the device:-

Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger

If that fails next thing would be to try and re-flash the operating system. This is done by using an SD card and loading the latest operating files onto it. The SD card slot is located under the keypad. A cross head screwdriver is required to remove the keypad. Search on symbol software download site for the latest. The download also has a readme with detailed instructions. Once the files are on perform a cold boot.

Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger. Drop the terminal in a cradle so that it runs on external power.

Hope this helps.

If you need any more help then please do not hesitate to contact us:-

Is it equipped with bluetooth? Do a search for bluetooth on your computer and it should bring up the bluetooth icon. Go "start", "search", then "all files", and type in bluetooth and search.
