Tip & How-To about Computers & Internet

CHANGING THE CMOS BATTERY



The inside of a computer is a bad place full of electricity and sharp edges.

On the electricity side always when working on you computer make sure that it’s still plugged in to the power socket and the power is turned off, this is to ensure that any static From you is discharged through the earth.

The inside of most computer cases are unfinished metal and has very sharp edges so be careful.

The first signs of a battery failing are:-

1) your clock starts running slowly
2) when you boot (start) your computer it has a problem finding your hardware (no hard drive, no cd rom)

To change the battery you need the following tools

1) a X-point screwdriver
2) an anti-static strap(optional)
3) a new battery (seems logical)

Then unplug all the cables from the back of the computer as you remove them make a note where they came from. (So when you finished you can put them back)

Move the computer somewhere where you can work on it with ease

Remove the cover by locating the screws around the outer edge (back) of the computer
Some computer cases only require you to remove 2 screws on one side then a panel can be removed allowing you access to the computers insides, others you must remove 6 screws and remove the whole case by sliding it to the rear and lifting it off.

Now make sure that you read the safety instructions about static.
Look inside you will see a round silver thing that looks about the size of a 10p piece (quarter). This is the battery itself, carefully lift the retaining clip and slide the battery out. That’s it removed now go to your local computer retailer, electrical retailer (Tandy/Radio shack) taking the old battery with you and get a new battery.

Back to your computer insert the new battery by lifting the clip and sliding the battery in.

Reinstall your case and plug all the cables back (you did remember to label them didn’t you)

Now for the fun part.

You will now need to go into you bios….

Right the bios is the god of your computer.

To access it, when your computer first starts you will see a black screen with white text.

If you look carefully you will see a line that says something like "press del for setup" or some other key (F2 or ESC or tab) this will take you to god's house where you can make lots of changes to the way your machine works.

It is also the place where you can make your nice computer in to a rather expensive door stop so be careful and don’t go playing with anything.

You will now be presented with a blue screen with a lot of options on it,
The one we want is load optimised/default settings.

Press the F10 key and type y the computer should now reboot.

If every thing went well then your computer will now be up and running.

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards You don't need to be a certified computer tech to upgrade your computer and remove malfunctioning components. All of the components inside your Compaq desktop computer are hidden behind the side access panel, and can be removed and replaced individually.

Turn off the computer's operating system and unplug any cables or devices connected to any of the Compaq's ports. Wait five minutes to ensure the internal components are cooled down. Set the computer case over on its side on a sturdy work surface. Touch either hand to the metal ports on the far-back side of the case to release any static electricity in your body. Remove both Phillips screws positioned at the back edge of the side access panel and set them in a container. Some Compaq models instead use a large plastic thumbscrew, which must be manually turned counter-clockwise to unlock the side panel. Pull the panel off the Compaq computer so the components inside the case are visible. Push in the plastic button on the edge of the front access panel. Pull the panel forward and to the right to remove it from the computer's case. Find the square metal box that houses the power supply at the upper-left corner of the case. Disconnect all of the cables connecting the power supply to the motherboard and the drives at the right side of the case. Remove the four screws holding the power supply in place and pull the entire unit out of the computer. Find the thin green memory modules positioned near the right edge of the motherboard. Depress the plastic locking latches connected to the top and bottom end of each module. Lift the modules off their motherboard ports and set them aside. Remove the two screws holding the plastic fan in place at the middle of the Compaq's motherboard. With some models you instead need to push down a metal clip. Disconnect the fan's cable and remove the fan. Lift off the metal heat sink positioned underneath the fan to reveal the square processor unit. Lift the plastic lever on the edge of the processor and pull the processor off the motherboard. Locate the line of horizontally positioned expansion cards near the bottom of the motherboard. Remove the screw holding each expansion card in place and remove the cards by pulling them directly upward. Locate the hard drive and optical drive in the metal bays at the far right end of the case. Remove the screws holding each drive in place. Push the drives forward and pull them out of the front end of the computer's case. Remove the screws positioned along the top and bottom edges of the motherboard. The exact number of screws varies between Compaq models, but will usually be eight or six. Slide the entire motherboard slightly towards the front of the computer case and pull the motherboard out of the case to finish disassembling the computer. Hope this helps.

Shizers way: Keep computer running. Lay it on it's side and remove side cover to expose MoBo. Take any thin object, "small screwdriver, knife point, wood shiskabob skewer. Pull back the battery retaining clip. Toss the old battery in the junk receptacle, unless you belong to Greenpeace and want to save the earth. Install the new battery. No need to reset bios because the computer supplies voltage to the cmos while it is running. Reset or re sync clock with internet. Done!

electric window for driver side failing to move glass, can i replace the motor myself


You can if you are handy and have some tools including the tool to remove the upholstery panel from the door. I have not worked on a Grand Am. Generally, the motors are bolted in to the door frame, though some are rivited. You might need a pop rivit tool. You will have to inspect for this when you get the panel removed. You will also need a large (long shank #3 probably) phillips (maybe a TORX). Pay attention to the electric connections.

Expect to pay up to $150.00, maybe a little more, for a operator (the motor and stuff attached to it. Remember, it is spring loaded and there are many, many sharp edges inside where you will need to put your hands, wrists, fore arms, etc. Also, expect to leave a little dna behind. The window is also heavier than you expect given the cramped space in which you will be working.

I am not in the auto reair business but have successfully changed about a dozen of these operators over the years. My best advice is when you purchase the rebuilt part at the auto parts place, casually ask the counter person if there is anything special you should be aware of while changing the motor. These people always hear the good, bad and the ugly about the parts they sell.

MVH240W making poping electrical noise. 10 year


Quite often this is due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.

The waveguide cover is usually about the size of a playing card and often held in place by a plastic rivet.

Sometimes it is in the ceiling of the oven.

It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!

The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.

If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart or Lowe's.

If your waveguide cover is burned, it will need to be replaced.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

If it's not a waveguide problem, it may be a bad high voltage diode or loose high voltage wire inside.

FixYa's Web site is currently not notifying us when replies to our Clarification Requests are posted, so please reply directly to me with your full number from the tag on the unit and your oven's color so I can help you with free do-it-yourself tips or an estimate.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
