How can i open the case

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. - rules

A computer case holds major hardware components such as a motherboard, hard drives and expansion cards.

Desktop cases come in a variety of designs but they all share a similar feature; the motherboard is fastened in the special tray attached to one internal side panel of the case. Typically you need to open the opposite side panel to access the inside of the case.

Switch off the computer.

Unplug the power cords from the back panel of the computer and from all attached peripherals.

Depending on your computer's set up, you might also need to disconnect other cables and peripherals, including keyboard/mouse, network and video cables.

Turn the computer around to face its back panel.

Unscrew two screws on that fasten the side right panel of the case.

Modern cases typically use thumbscrews; loosen and then remove such screws with your fingers. Other cases employ release buttons that you need to push.

Consult your computer owner's manual if in doubt.

Slide the case side panel back to open the case.

Hope this helps.

Can a speaker be internally installed

Shut the computer down completely if you are installing a PC speaker in a computer that you have already built.

Disconnect the power cable, and bring the PC case to a sturdy table or workbench.

Open the PC case.

A PC case sometimes has a release lever that you can use to slide the cover off without tools.

If your case has no release lever, look for a series of Phillips-head screws on the back and remove them before sliding the cover off of the case.

After removing the cover, place the case on its side so you can access the motherboard.

Locate the connector for the PC speaker near the front of the case.

Generally, the connector has two wires black and red and a black connector with four holes on the end.

Examine the black connector, and note the hole a dot or arrow next to it.

This end of the connector should align with pin 1 on the motherboard.

Look for a bank of pins on the motherboard, near the front of the PC case.

Near the bank of pins, there should be a guide explaining the purpose of each section of pins. Examine the guide to find the four pins labeled "SPK," "SPEAKER" or similar.

Place the connector over the four corresponding pins so that the side of the connector marked with an arrow or dot goes over the pin marked "1."

Hope this helps

Bios password


Bios password, time, date and other user settings are keeped in a CMOS powered by a 3V battery.

Removing this battery for a couple of minutes resets the BIOS password and also the time and date.

It's very easy to do so in a Desktop PC, because the battery is visible on the motherboard after opening the case, and it can be removed simply by using a non-metal tool, even a toothpick.
But it is complicated at laptops, because accessing the motherboard means taking the whole thing appart, and that requires some tools and skills.
In both situations (desktop and laptop) the power cord must be disconected before opening the case, and of course the laptop battery should be also removed.

My advise is if you are not experienced with opening the case of a laptop, to ask a qualified person to do that.

Good luck!

Can't log in

I'm assuming what you're trying to say is that you're trying to access the bios of the motherboard but it's password protected. To reset the password and all other settings of your bios you can open up your case, pull out the little battery for a few seconds and then put it back in. You should now be able to access the bios

Access to motherboard of an old Dell Inspiron 5000 to remove unknown bios password. Thanks

To reset the BIOS read the information from this link.

In case of a laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

Where we can find the intel id number in the mother board?

On the board
  • Turn off your computer and unplug the power cord. Open the case and access the motherboard
  • Locate the peripheral slots, which are long, thin connectors that sound cards, video cards and ethernet cards plug into. (Such cards are made of the same circuit board material as the motherboard and will be sticking out of the board vertically.)
  • Look to the left of the last peripheral slot. There should be a identification number silk screened onto the motherboard itself. It may be abbreviated, in which case you will need to copy it down and search for it on Intel's website.

    Removing acer motherboard to reset password

    You don' t have to remove the motherboard. Remove the CMOS battery. The CMOS battery on a laptop is many times accessible from under the computer when you take the battery out. I've found them just outside of the main battery compartment up under the palm rest. Acer may be different. If you can't find it by looking up through the holes opened up by removing the access covers in the bottom of the case, you just may have to split the case to get at them. Just be careful when you do it. All cases come apart, but many require the removal of a number of screws first.
    Try removing the battery for about a minute first (with the system unplugged, of course.
