Question about HP Compaq Presario 2200 Notebook
Where can I find the CMOS battery? Is it hard to remove?
Desktop PCs use a battery to keep time when the they are off, much like a watch. Like a watch, the battery needs to be replaced when it runs low on power. Replace the battery using the steps below.

Its actually not as easy as this guy is saying, being that i myself have opened mine twice already and took the battery out. Are you having problems with the 2 beeps and says press F1 to continue and F10 as well?
Anyway, i am almost certain that is its the cmos battery being that when i took it out for a little bit and put it back in, it actually stayed on the boot up option longer.
Step 1 - Remove the memory modules (RAM cards) first, simply to avoid damage, then open up the Wi Fi card below it. you can either completely take it out by unplugging the two small wires attached, but i would suggest leaving them on during this delicate process and just taking the cord out of where it is wrapped around where the ram cards were. Just for the fact of confusion of not knowing later on what cord goes where.
Step 2 - remove the screws from your hard drive, then simply grab from the bottom (the opposite of where the arrows are) and lift up. Now place this aside and and remove your battery if still attached.
Step 3 - Remove all the screws on the bottom of your laptop, then where you have your DVD rom just pull it out with ease. this way all your main components besides your motherboard are all safe and one less thing to think about.
Step 4 - this part is a little tricky but not hard, first you will have to open the laptop so the screen is facing you, then, where the two hinges that hold the laptop together you have to feel for an opening there on both sides and pull up (where it has your startup button above the keyboard) dont worry you wont break it just dont be too forceful apply force gradually. Once you have this piece off you will see 4 screws connecting the keyboard to the base, remove these screws and keep your keyboard in place and gently close.
Step 5 - now flip over your laptop back to the bottom, now the easy part, all you need its something like a paper clip or a flathead screwdiver. Where you place your battery you will see 4 small little rectangular openings near the top of the plastic, this is what is holding the laptop together. so gradually between the silver and black part slowing unclip one by one and make sure you get all for clips, then start rustling off the rest of the shell and viola everything is now exposed.
Step 6 - you will find the small lithium battery thats 3v you cant miss it. but i would really advise taking it to the pros to fit size your battery just make sure you bring the necessary information for this battery, or just bring the battery itself. you cant just go to walmart and get a 3v lithium battery, believe me i tried and they are not the same size.
I hope this tutorial better helps you understand how to open this laptop with ease instead of having questions that were not answered in previous tutorial.

Shut down your laptop and disconnect all power sources. Turn the laptop over and lay it face down.
Remove the screws that secure the hard drive cover and remove the cover. Take out the remaining screws that secure the hard drive to remove it.
Locate the RAM (random access memory) and wireless card cover. This is often located in the center of the laptop. Remove the retaining screws and take off the cover.
Remove the RAM module by spreading the retaining latches on each side. Tilt the RAM module at an angle and slide it out of its compartment.
Disconnect the cables from the wireless card and remove the screws that secure the wireless card to the motherboard. Remove the wireless card from the laptop.
Locate the CMOS battery. It is about the size of a coin and is secured by a clip. Unclip the CMOS battery and remove it from its compartment. Insert the new one and reassemble the laptop.
