• HP Compaq 8100 small Elite for: CMOS battery change

  What battery I need to buy to replace battery CMOS (lose the BIOS date/time).

  All traps to replace?

  @LechKL, welcome to the forum.

  Here are the computer hardware reference Guide .  On Page 46, you will find a guide to replacing the battery.  Read this section very carefully.  In most of the computers battery is a CR2032.  The instructions state that you must use a spare battery supplied by HP.  However, you can us HP Partsurfer to see if they recommend a battery.

  The process should be simple.  There are detailed photos to help you.

• Compaq Presario S4500UK won't start after disconnecting from the wall outlet. What is a CMOS battery problem?

  Reconstruction of recent software with HARD drive internal extra (March 2011) under Windows XP/Linux dual-boot installation worked fine.  CD/DVD RW drive, started giving errors so replaced cyclic redundancy check drive a week ago.  All still OK.  Change of electricity supplied and increases energy use conciousness off the machine to the outlet of the overnight after normal shut down.  Machine will not re-start not in the morning.  Not load BIOS; all lights came briefly and then die after 3-4 seconds with power still led on.  You can get a similar effect by plugging the keyboard into the PS2 Mouse Jack I did once!

  After 20 minutes or so try all kinds of things managed to boot from the CD of Linux.  Shut down/restarted and everything is fine so I don't switch off at the wall.  Also seems to be OK after brief power off for 5-10 seconds but the problem persists with any long disconnection.  It seems that after 10 to 15 minutes from power-on and 2-3 attempts to restart, BIOS comes up and all is well, but he stopped in the middle of a start of Windows or Linux on a couple of occasions.

  Am I right in thinking the problem might be the result of a dead CMOS battery?  The reason that I ask is that the clock seems to keep time OK and there is no apparent problem with the BIOS once it loads.

  Any help/advice would be much appreciated.  New config info below.

  I don't have all the answers so I went forward with replacing the CMOS battery, but that did not help.  The problem is also obvious if I turn it off and leave it for an hour or more before trying to restart even if I do not unplug the wall plug.  It seems to take about 15-20 will start again before it fires.  I would be really grateful for any clues as to what is wrong.

  OK, guys.  I finally solved the problem.

  After you have calculated the power needed for the config curent, I discovered that, using various ways to estimate, he walked between 321W - 383W.  It was pretty weird that the only thing I added was a HARD drive and a memory stick and the wisdom of the other guys on this forum, it's that there is a lot of capacity within the factory installed power of 250W.  Yes and here's the rub: the modern replacement devices usually have upgraded capabilities and use more power.  And so when I replaced the drive CD/DVD RW added a few watts, as the sectoral approach of the floppy drive.  It appears also that the optical USB mouse needs more juice than the good old PS2.

  I just installed a new 450W PSU Powercool and Bingo!  The processor is faster, too.

  Hope that my pain and trauma saves someone else having to suffer the same.

• Presario 2111 cmos battery replacement

  I was trying to find the battery type and the location of the RTC (CMOS BIOS) battery that is used in the Compaq Presario 2111EA laptop, as the User Guide and the maintenance manual does not mention the battery or how to replace it.

  Hello

  I disassembled the laptop and find the CMOS battery on the underside of the motherboard.

  It was a normal Maxell CR1220, 3v lithium (like a watch battery) button which are clips in a white plastic stand. I ordered a few 40mAh ability with a life until 2018 for some books.

  I would have thought that a rechargeable type Lithium-ion would have been used instead of the non-rechargeable type. It is a pity that was not the result of the form of the Mini PCI door to accommodate the change the battery because it is located near the door on the bottom of the laptop. It would have been too easy and owners could change the battery themselves without having to disassemble the laptop to change a battery.

  It was for sound technical reasons.

  Thanks much for the reply

• HP/compact D530 desktop: Recplacing CMOS battery for HP/Compaq D530 desktop

  Hello

  I have three, exactly the same thing, computers to Office HP/Compaq D530. The CMOS battery needs to be replaced on all three.

  Problem is that I don't know where on the motherboard is the battery. It's a motherboard very small size. It seems to be under something, but before I take the computer hand (I'm not a geek), it might be a good idea to know exactly where to look.

  Thank you!

• Compaq Presario CQ5110Y Desk: Change a computer fan

  Hello. My Compaq Presario desktop computer, product #KY821AA, is 7 years old and not under warranty. I have no technical expertise, but I don't change another fan in the computer, which was easy to access.

  In my view, that the fan in the computer case power supply area must be changed. It is making considerable noise on a regular basis, which it did not before. My questions are the following:

  (1) is there a link to a video or a website that could show me how to open the my computer power supply area (I already know how to open the case on the side of the computer)?

  (2) if I can get into the power supply area, I have to take the power supply on and bring it to a store to get a new or would it be easier to just replace the computer fan in the power supply area, which is the only reason why I want to go to the power supply area.

  Thank you.

  If you notice, the PSU (Power Supply Unit) in the PC is locked up in a case of steel mesh.

  There is a very good reason for it.  Inside of this case are capacitors that store a LOT of current, so that if you accidentally touch one, you could easily be electrocuted!  If not killed, you risk very severe electric burns.

  Leave the only PSU case and replace the power supply with a new - what is much safer.

  Good luck

• Compaq Presario CQ5500F: Compaq Presario CQ5500F has no support for cmos battery

  I'm refurbing this machine and it does not have a CMOS battery on the motherboard support.  See where it should be, but looks like it was never installed.  There is a new technology that does not require a battery?

  Hello

  The CMOS battery (or RTC battery) is used to allow a computer to maintain the non-volatile memory Basic Input Output System (BIOS, IE).

  Whitout CMOS battery, the computer will boot but you may need to change every time you start depending on how configure you your machine. The function of RTC battery is not important now because a lot of people now use the timer/clock NTP or internet.

  Kind regards.
