• 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 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.

• 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.

• 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

• Satellite Pro S300-120 does not start after replacing the CMOS battery

  Hello

  My friends laptop - a S300-120 - was having a few problems.

  I replaced some parts about this before, including a screen crack with no problems.

  However, he began to refuse to start saying "out of battery CMOS, Press F1 to enter setup". Of course you would have to do this, set the date and time, except & restart only to get the same message. We have replaced the CMOS battery with a with the same serial number and now the laptop will not boot.

  It does one of two things.

  It is one) seems to turn, turn to the top disk & CD player, cooling fan is 100%, then flashes the POWER ON led once, twice by orange, and then green to 1/2 second intervals, with no response from the keyboard or LCD.

  Or (b) turns on, turntable, does not turn up to cooling fan, POWER ON witness remains stable, no response from the keyboard or LCD.

  I re-assembled the laptop several times & can not find all the missing fittings or obvious signs of damage.

  The only thing I can think is that the motherboard has been damaged - somehow find replacements is delicate.

  Any ideas?

  Hello

  (> It is a) appears to turn on, turn the disk & CD player, cooling fan goes to 100% and then flashes him

  POWER ON led once, twice by orange, and then green to 1/2 second intervals, with no response from the keyboard or LCD.
  Usually, if the voltage in abnormal feeding malfunctions when IN DC will be blinking orange.

  In my opinion, it looks like a problem with the motherboard :(
  Eventually, you will need to replace the mobo ;(

• Portege A100 - where is the CMOS battery?

  Hello
  Can someone tell me where the CMOS battery is located in a Portege A100, please?

  Thank you in advance.

  Hello

  Why, you want to know where is the CMOS battery? You want to exchange it?

  I think this question can anybody answer here because it s only a user to user forum. Never saw here authorized technicians or anyone from Toshiba.

  Regarding your question, you should contact the nearest authorized service provider. They can answer any technical questions and also to exchange the battery for you. ;)

• Qosmio G20-106 - exchange of the CMOS battery

  Best regards

  unclescrooge

  Hello

  No, as I know it is not possible to do
  As far as I know the CMOS is welded somewhere on the motherboard and you would need to disassemble the whole laptop. This can be really, really painful procedure.

  But why do you want to remove the battery?
  The CMOS battery is charged and it should be possible to load it again.

• Re: Where is the CMOS battery in Toshiba NB100?

  Hi guys,.

  I disassembled my nb100 and have been to look at the motherboard for centuries, trying to find the CMOS battery.
  Basically, my netbook is not in the bios, it is just stuck on the Toshiba start screen.
  so I thought I would try to remove the cmos battery to see if that could fix the problem.

  So if someone could please tell me where I could the cmos battery?

  > Basically my netbook will not go into the bios, it remains just stuck on the home screen Toshiba.
  > so I thought I would try to remove the cmos battery too see if that would solve the problem.

  I doubt that this will help you solve this problem
  First and foremost the CMOS is soldered to the motherboard (in most cases).
  I think there must be a problem with a motherboard if the laptop is unable to pass the POST (power on self test).
  Basically, all that might be affected; RAM, etc.

  I think you should check the RAM first, if that is not enough, then an ASP should try to reflash the BIOS, otherwise the motherboard needs to be replaced.
