CMOS battery on Compaq Presario v2000

\015 Where can I find the CMOS battery? Is it hard to remove?\015

Answers :

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.
  1. \015\012Unplug all cables except for the power. Write down each cable location if you do not already know where it connects.\015\012
  2. \015\012Unplug the power cable and with the power cable removed press the Power button on the front of the PC.
  3. \015\012
  4. \015\012Remove the screws on the rear of the PC.
  5. \015\012
  6. \015\012Slide the side panel off from the rear of the PC.
  7. \015\012
  8. \015\012Locate the battery. It is a small shiny round metal wafer (like a larger version of a watch battery).
  9. \015\012
  10. \015\012Remember which direction the battery is installed. Usually the engraved side, the positive side, is face up. Remove the battery from the main board.
  11. \015\012
  12. \015\012\015\012Acquire the battery and replace it in the same socket it was removed from. Make sure the new battery is installed in exactly the same orientation as the previous battery. (Warning: There is danger of explosion if the battery is not correctly replaced. Replace only the same or equivalent type of battery.
  13. \015\012
  14. \015\012\015\012Replace a side panel by matching the side panel tabs with the tab openings in the case.
  15. \015\012
  16. \015\012\015\012Connect all cables and turn on the PC to set the time.
  17. \015\012
  18. \015\012\015\012Hope this helps. Would appreciate if you rate it. Thanks.2b4f1b5.jpg895f1d9.jpg
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.
