• Portege R100 - replace the CMOS battery

  Can someone point me in the right direction to get instructions on how to do it.

  Thank you

  Hello

  It is not easy to remove the battery from the motherboard RTC! It s really complicated because you will need to disassemble the whole laptop in the right direction.
  As far as I know, you need to remove the keyboard and the bottom cover.

  But why would you remove the RTC battery?
  If the RTC battery is empty then you can reload again.
  The laptop must be connected to the power adapter and must be turned on for over 24 hours.
  That would recharge the battery of the CCF.

• 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?

  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 ;(

• 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.
  Check this box!

  Hello

  Battery CMOS is needed to keep the BIOS settings.
  It seems that the CMOS battery is empty if you need set the date and time always in the BIOS settings. But the CMOS battery has nothing to do with the floppy drive.

• 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.

• I'll replace the CMOS on an old Pavilion 751n battery. What then?

  I'm going to replace the battery of the BIOS on old Pavilion my mother 751n.  What I don't know, is what will happen: will I need to Flash the BIOS (because, for example, there no information because the battery died a long time ago), or the BIOS on Board will be still intact?  It still will automatically detect what are the devices on the computer (including a video card and a new hard drive; the old drive hard doesn't have a CHIP checked and no longer boots, and I'll restore the PC to Žtat via recovery CD after installation of a much larger disk).  He will recognize that the RAM of the computer has been quadrupled during its original specifications?

  In short, I have to do something special, once I replaced the CMOS battery to avoid having a difficult time in the computer?

  Hello

  None of these things should be a problem.

  Video is automatically disabled. The BIOS does not care what the material is in the slots PCI, CD-ROM etc.

  They will all be rediscovered and everything should work.

  What I mean by changing the default value is if you have changed the default boot in something else, order etc.

• CMOS / RTC battery for Satellite A100-326?

  Hello

  I'm after a CMOS/RTC battery replacement for my A100-326

  I had my machine open and find the battery, but there is no model number on it.

  I contacted Toshiba support center and they told me that the battery is part of the Board of Directors and management as a whole needs to be replaced. However, if I can find the reference to the battery, I have a friend in a computer store that will replace it with a new one.

  Any help would be great. Thank you!

  Hi Aman,

  Thanks for posting your query in Microsoft Community Forum.

  It seems that the battery is exhausted after a long period of time. You receive this error message was probably at the end of the battery life.

  I ask you to refer to the suggestions by Barry Kundalam replied on 25 March 2013.

  You can contact the manufacturer of the computer and replace the battery.

  Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

• Adjustable 430CDT Pro - how to replace the CMOS battery?

  Two questions, if I could.

  1. the old new 430CDT - does anyone have simple instructions that go I would find the CMOS battery and replace it without destroying the computer in the process? I suspect that it is hidden under the keyboard, but have no idea how to do to remove that. (I'm not very super-friendly upward on computers.)

  2. How can I get back in to old posts and give points for helpful answers?

  Thank you!

  > 1. The old 430CDT yet - does anyone have simple instructions that go I would find the CMOS battery and replace it without destroying the computer in the process? I suspect that it is hidden under the keyboard, but have no idea how to do to remove that. (I'm not very super-friendly upward on computers.)

  I m not very well, but I doubt you could get access to the only keyboard removing CMOS battery.
  Usually it s placed on the motherboard but it s need to disassemble the whole laptop and believe me. It's really complicated and mostly impossible for some who never disassembled a laptop

  So if you ask my opinion: contact a technician in downtown and ask for help.

• Re: Replacement CMOS / RTC battery for Satellite A200-244

  Hello

  I'm after a replacement of the RTC battery for my A200-244

  I had my machine open and find the battery, but there is no model number on it.

  I read the post by saying that the battery is part of the Commission and the Council must replace, but if I had a model number for the battery I could very easily unsolder old and replace with new

  Hello

  What s wrong with the RTC battery? Is it empty?
  The RTC battery can be charged by the adapter or the main battery while the computer is on. You must charge the battery 24 hours long.

  In addition, it seems that the A200 series uses the 3.0V (14mAH 17maH) RTC battery
  I found some that support these values.

  Battery RTC (Maxell ML1220T10)
  Battery RTC (Maxell ML1220HT10)
  Battery RTC (Sanyo ML1220T28)
  Panasonic ML1220/B of the RTC battery

  But to be honest, it could damage the whole motherboard while trying to remove these batteries as mentioned in other threads his welded so I might be really complicated
