• 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.

• Equium A210 - replacing the CMOS battery possible?

  My Toshiba Satellite A210 - 1 4 seems to have a CMOS battery problem because it does not keep the BIOS settings.

  I bought a replacement battery and a/c mains adapter to remove the a/c power problems but the POST beaps and CMOS keeps a checksum error and once in the BIOS and save the settings, it starts successfully, but if the laptop restarts or is off this all over again. I've also updated the BIOS successfully is not of the BIOS chip. The only thing I can think is to replace the CMOS battery - is it possible?

  I read that some are soldered on? Would this laptop Toshiba service to replace the CMOS battery / audit failures - if so, how much would it cost, or someone else can do that the laptop is out of warranty.

  Advice please?

  Hi Emases2010,

  As I know some batteries are fixed/soldered to the motherboard and t is no substitute, but I think that only a laptop computer technician can give you a detailed response.

  Normally, you can load the CMOS battery if you leave the AC adapter plugged in overnight or in the best case 24 hours. After this, the battery must be fully charged.

• Pavilion dv6 2170 clock problem after replacing the CMOS battery

  Hello world. Sorry for my bad likely English

  OK, so the problem started since I changed my laptop CMOS battery. and to be honest it wasn't whit any problem the clock when I replaced it but I if this may be the cause of another problem that later I figuered what the problem was because of the RAM.

  in any case, I changed the Rams and this problem has been resolved. I just set the clock of the BIOS and rebooted the system. After awhile I figuered that windows clock is not fair. I restarted again and saw the BIOS clock. It has been reset for 2009! even when the laptop battery and power supply are attached the BIOS and windows continues to change clock! I even changed my windows and I replaced the CMOS battery with the former, but nothing helped. It seems really strange, but I don't think it's maybe a hardware problem there a driver or something for the CMOS battery... need your help! Thank you!

  You mentioned that the BIOS has been reset for 2009? This means that there is a problem with the current or any leak and the BIOS has been "reset" back at the root of the plant. I'm afraid you have shorted something when you changed the battery not be grounded.

  Worst case is that there is physical damage to your motherboard and there is nothing you can do about it, probably broken a capacitor - who cannot hold a charge to prevent the reset of the BIOS clock.

  However, you can try this.

  Completely, unplug your computer, remove the laptop battery, etc... Then browse 'Guide' your computer for the "hard physical reset" for your CMOS. I don't know what it's like on a laptop, I only did it on desktop with riders. Be sure to follow the directions precisely.

  -Make sure you are properly grounded. touch the metal parts that is grouned before touching anything on your computer.
  -the hard reset should be done for at least 30 seconds, this ensures that the power is completely served the system. Then you can set this back.

  Try this a couple of times, first without removing the CMOS battery and 2nd time after remove CMOS battery and placing it in.

  Good luck.

  BTW, you can also try running without your new memories (if there is more than 1 stick, try them separately). In fact, I would probably try first before doing a hard reset CMOS. The reason why I didn't say earlier, it's because I have assumed that you already tried this.

• 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 ;(

  I have some old Tecra R10 - 10W

  Aftert long in the cupboard, it says CMOS battery error and after charging I can't start on the old password (bios) system.

  How to reset the password of the bios and is also required for cmos battery and I can do it myself?

  I thank...

  You can change battery cmos your np for bios pasword use google auto, I hand a mini hp with the same problem and initiated a program that has been reset using error code when it is inserted the wrong password 3 times into the line, then I used the error code in the program and got the password restarted hp and password inserted now is job bp. Do I have also an old tecra and difrend problem with it, everything in good standing sims but used laptop start first ferry, after several restarsts shovs splash screen, then runing bp, restarted again, same story, it restarts several and then is runing again, leading with outside the same monitor thing, ideas?

• 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.

• Tecra M10 - CMOS battery is low and powers down and upwards automatically

  Toshiba TECRA M10 - 10W
  Model no PTMB1E-00P003EN

  This laptop was working fine last week and is only about 1 year.

  Now to the power he reports the CMOS battery is weak and penetrates into the configuration screen to set the date and time.

  Once this is done, it shuts down and no more automatically, but everything works the CPU fan to high speed, no attempt to start etc.

  If you press the power button with the fan running, it will be power downwards and upwards (while it is still connected to the power grid) and again to report a problem with the CMOS battery.

  Any ideas on what is wrong and what can be done to fix this?

  Hello

  First the CMOS battery can be charged while you let the connected AC/DC adapter, for example 24 hours a day. After that, the message CMOS battery shouldn't t appears more.
  Check this box!

  The power automatically power cycle on and off can represent a danger due to a hardware malfunction can you start in Windows or in fact that happen before?
  Maybe it s overheating and you need to clean the laptop using a jet of compressed air.

• No in the Satellite C50D-B CMOS battery

  My Toshiba C50D-B does not remember that numlock is out and continues over time if the battery is removed or no.
  Then, the laptop starts by saying that the battery is low.
  So I wanted to replace the battery, but I could not find.
  In the manual there is no talk of replacing the cmos battery.
  And when I look at the Board (after the opening of the back) I can't find not all batteries.
  I can find an empty place in the motherboard, which suggests that there should be a battery, but it is not a connection to it.

  How do I replace the battery or is it not possible? In the latter case, it's a shame, because things don't work properly.
  I have the laptop a year, but now I am so tired of correct every time that the NumLock and occasionally the time/date, I want to solve this problem.

  The empty CMOS battery didn't need to be replaced...
  You need to load it again.
  How?

  It's easy... you need to connect the power adapter and the laptop must be turned on for at least 18-20 hours
  After the battery has been fully charged, the CMOS battery will start to load too.

• TE2100 frozen and CMOS / boot problem

  I have an old TE2100 of 3.5 years.
  When I worked on this subject, it froze all of a sudden. No reaction on the keyboard or the mouse. I had power is down by holding down the power button.
  After that the laptop wouldn't turn on more, so I removed the battery, cdplayer and played a little bit. After a few minutes, it started working again for some reason any uncertain.
  After I turned on the machine, but I have a
  * bad crc checksum, check the system etc etc. Replace the cmos battery *.
  Message.
  After that the laptop worked normally (with the exception of the date system, which has been reset to 2000) until it froze again and again and so on. Now he refuses to swith on at all. When I press the power button, the green light comes on, but nothing happens. It doesn't matter whether on AC power or battery.

  The laptop is out of warranty and 6 months virtually out of it is of economic life. So I don't want to spend too much money on repair. I'm pretty good with electronics and other things, and the cmos battery replacement should not be a problem as long as I find a new one here in Holland. However, I highly doubt that a bad cmos battery is the problem here. Windows should not fail because of an empty battery I think.

  I have someone out there who has any suggestion on how to solve this problem or who can tell what is probably the problem? Thanks in advance!

  Hello

  Well, if you want to replace the CMOS battery you must open Notepad. In this case, you need to remove all the covers and keyboard.
  Unfortunately, I put t know exactly the battery place, but I think that it of not difficult to find.
  In addition, you can contact the service partner to order this cmos battery and to ask him detailed information.

  Good bye

• Pavilion 13 x 360 convertible: convertible laptop CMOS battery HP 13 x 360

  We are working on 13 a friend x 360 laptop which has battery issues. We replaced the battery and still having problems with time remain up-to-date and slow start so assume it's the CMOS/RTC battery. The problem is, we can't find! We have removed the mobo and it simply isn't there. I can't find videos or manuals that correspond to this laptop specific. All show a very distinct CMOS battery.

  Any help is appreciated.

• Satellite A50 cmos battery replacement

  Hi, does anyone know the bios battery where satellite A50 series? mine need to replace soon.

  Hi Chang

  Replacing the CMOS battery on laptops is not as easy as on the desktop. If you want to do it alone you have to disassemble the laptop and you should not do if you have no experience with it. Before do you it alone, please contact your local dealer or service and ask how much the replacement costs.

  Believe me, that a small mistake may be responsible that unity don t start anymore, and then you can have a real problem. If you want to do it alone and at your own risk poster again.

• MS200 HP all in one computer - replace the CMOS battery

  Hello

  Can anyone help with this please?

  Need to replace the battery CMOS but can't finy all information on how to access it.

  Can find information on how to access hard drive, memory, and how to remove the stand, but nothing on how to access the CMOS battery / motherboard. The rear panel does not seem to have clear access points to remove it.

  Thanks for your help!

  For the benefit of anyone with a similar problem, figured out how to remove the envelope which was really very simple (is always when you know how).

  To remove the Panel, you must first remove the stand. From there on, remove the cover on the back that conceals the hard drive. Remove the screws that hold the hard drive and a DVD burner in place.

  Slide the DVD drive, and then you can gently push the lid with a knife butter blunt or similar to push the housing into the slot of the dvd player . Once it begins to pull him out just gently work your way around the edge.

  Once the case is off, the CMOS battery is fairly easy to find.

• W530 does not illuminate when the CMOS battery is connected

  Problem:

  I can't get my laptop to start (it blinks just 3 times battery icon, without to need laptop power (won't start even fan)) unless I disconnect CMOS battery, external battery and power first. Disconnected battery and CMOS battery, I can get the computer started connecting the AC (the computer then starts immediately without the need to press the powerbutton). Once the computer has booted, everything works fine (get warnings during start-up due to removed CMOS battery and must adjust date/timesettings every time in the operating system) and it is possible to restart without problems. I tried the following:

  Attempted fixes:

  (1) replace the CMOS battery and checked the required voltage is present using the multimeter

  (2) delete all memory modules. Has not made a difference, because it never reaches the verification of memory (where it would beep several times due to lack of memory) unless CMOS has been reset.

  (3) update BIOS of 2.57 to 2.63 without change

  (4) by pressing the button of power 10 times and then maintained for 30 seconds did nothing.

  I'm out of ideas after many hours of web browsing, so any help will be greatly appreciated.

  Kind regards

  It will be like this if the CMOS battery has failed and is in short-circuit. Try another battery CMOS
