• Satellite A40-211: RTC battery is low or CMOS checksum is inconsistent

  Hello

  I bought a functioning Satellite A40 - 211 of one of my friends, who had a defective model A60 from where I took the fast hard drive, the memoryupgrade and the internal wifi card, but the only annoying on the A40-211 new thingie is the message that the RTC battery is low or CMOS is incompatible whenever the laptop is turned off and turned on again (which also happens when a warm reboot is done)

  After checking the laptop for any other problem (there was none), I decided to replace the RTC battery with a new... about 17,-euros in total cost. (Of the disassemble the whole laptop, but it has more than once 100 or so with other models, takes 15 minutes to disassemble and put them all back again once)
  Did charge it new CCF to power the laptop up and leave it for at least 24 hours... (the manual says to do)

  No results... always the same... boring message.

  I also tried to reflash the bios, but the version 1.50 seems ok and cannot be replaced by the programming software.

  So, we have a good laptop to work here, but with an annoying message that cannot be solved?

  Anyone with a good tip?

  OK, a response to myself, because I've been tracking something here...

  I replaced the hard drive to another laptop (Satellite A60 series) to the A40-211... installing Windows could be transferred, since the IDE controllers are the same... then just install some other vga - and sounddrivers to operate...

  But... somehow with the new hard drive and therefore installation, date/time settings are lost after a restart or power off...
  I also discovered that the installation of 'old' will not go into sleep - or standbymode... it will only close...

  Then. I'll make a recovery disk hard 'new' facility, because it is faster than the original that came with the A40.

  I'll keep things updated here... also because this isn't a real solution to the question...

  Now, the question is: what makes the time/date setting go lost after this laptop with a non-on-this-laptop-installed-OS off the power?

• Satellite A40-S161: RTC battery low

  Hi guys,.

  I need urgent help. I have a laptop, Toshiba Satellite A40-S161, which gives me the following error whenever I restart the machine "RTC battery is low or CMOS checksum is inconsistent."

  I took the laptop to my local dealers who replaced the CMOS battery and advised me to leave the machine 'fees' for 6 hours [what I did], and the problem persists. Is there advice that I could follow to remedy the situation?

  Hello

  AFAIK in user? manuals it s nice instruction how to deal with it. If I am memory while the unit must be turned on, connected to the power supply current minimum 8 hours.

• Satellite Pro A10: RTC battery is low or CMOS chesksum unstable

  I have a Satellite Pro A10.

  When I turn everything first laptop computer on I get RTC battery is low or CMOS checksum is unstable - press F1 to set date/time. When I press F1, I get a beep and it's everything that happens. I'm unable to had to set up or do anything at all with the installation program.

  I kept it plugged in for 24 hours, but still the same results. I replaced the CMOS battery with a new. But even once, I get the exact same results.

  All that happens when I press F1 and a sound signal. Is this a sign that I have probably a problem with the motherboard?

  You can access the BIOS and could try to set the default settings, and then save the settings and start again.
  If it doesn't, then it must be another reason for this message.

  My first thought was that this error pops up because the BIOS battery is empty.
  Usually such charge as described in your ad should help get rid of this message.
  But it seems that there is a more serious problem

  I m not quite sure what this could be, but the hypothesis that a motherboard could malfunction is not wrong.
  I think that a fault of mobo might this causes too.

  But in my opinion a mobile technician must check to make sure what's wrong.

• Satellite A45 - S121 RTC battery low or unstable CMOS

  I have a Toshiba A45-S121 that I got from a friend who has left the country...
  I keep going back to the same message over and over again and cannot activate it because it keeps doing again and again.

  The message is: "RTC battery is low or CMOS checksum is inconsistent, press F1 to reset the date and time." It would have been great if it was, that I should have done, but at this stage no button does nothing, and the only thing I can do is to restart... I looked on the net, and someone said to recharge, the main battery for 8 hrs, will do... NOT.

  Another said to rest with charger for 15 h and have the laptop on at the same time... NO help there.
  Another was told to change the battery Cmos... Did this... NO help.

  I tried F12 thing... the computer is located in the startup Toshiba logo, and as soon as I press another key, it goes back to this message... I can't do the BIOS, and I can't run it from a CD, until I have this message.

  HELP PLEASE.

  Hanks a lot.

  > The message is: "RTC battery is low or CMOS checksum is inconsistent, press F1 to reset the date and time." It would have been great if it was, that I should have done, but at this stage no button does nothing, and the only thing I can do is to restart

  Usually this or similar message appears if the battery CMOS/RTC would be empty.
  In this case, you should be able to solve this problem of the RTC battery.
  How to recharge?
  The laptop must be turned on and connected to the power supply for approximately 24 hours.

  But I see you've also already replaced the RTC battery and this message still appears.
  In addition it seems that you are not able to access the BIOS to change the date/time settings.
  Well, this would mean that there is a serious problem on the motherboard

  I think that only a laptop computer technician would be able to help you.

• Satellite P100-423 - RTC battery replacement

  I'm happy enough to replace the CMOS / RTC on Satellite P100-423 battery because the device is out of warranty and the battery needs to be replaced.
  Le-423 is a build of Costco and not much found after the mandatory, manual Google and research forum.

  Can anyone recommend a type satisfying to do this, no clue on the former.

  Thank you

  Hey,.

  Are you sure that the RTC battery is replaceable?
  I ask this question because as much as I know it is not possible on all s models and if it is replaceable you can find the specs on the battery itself if you disassemble the laptop.

  Normally, this battery can be charged if you leave the AC/DC adapter plugged in for 24 hours. Have you already tried?

• Issue of Pro 6100 satellite about the RTC battery

  I know it's a huge topic which will be discussed on, and my Toshiba is screwed. I even did a lot of research and found it disappointing that my Toshiba may not be repairable, but I have a question;

  When I boot my Toshiba, it looks good, and I can run normal programs (I get the error of bad RTC battery), but for some reason, the Toshiba randomly freezes and I have to stop it after 5 to 20 minutes to use me.

  I tried to leave it on, as some other forum topics proposed to charge the bettery RTC and it went okay, then 20 minutes later, it froze and I had to reboot.

  Sometimes it is not still turn just after that I have forcefully arrested, so I have to wait from hours to days so he can go back on. But it's useless cause it hangs again.

  Any input on it's great and I'll take advice for this problem. I want the RTC battery but it keeps freezing on me, if I want to find a way to prevent this. Thank you!

  PS: ASP Toshiba Theres two locations in my city (Markham, Ontario, Canada), so if all else fails, I'll take the laptop with my father at one of these places.

  Hello

  If you want to reload the RTC battery you don t need boot up the laptop.
  You can simply connect the AC adapter to the laptop and allow it to charge for a piece of 8 to 12 hours.

  The freezing issue for me sounds like an overheating problem. This can happen because of the dust and debris inside the laptop. In such cases, cooling modules may not work correctly.
  In case you I recommend first charging the RTC battery (don t need to turn on the device), then to clean the fans (you can use carefully vacuuming).
  If the laptop freezes then you could try to reinstall the operating system.

  If all of these tips n help so you should ask the ASP for the verification of the laptop.

• Satellite C50-B-19V - RTC battery low

  Hi all

  I ask your help.

  I have 15-inch Toshiba Satellite C50-B-19V laptop.
  It is 2 years old.

  I get RTC battery low message the laptop turned OFF for awhile (without adapter).
  When I turn it on, I have to re - set the Date and time in the BIOS.

  So I fully recharge via an adapter, and every time I put it to sleep the clock stops just when I put on standby.
  So if I put for example standby at 10:00 on March 2, 2016, and I turn it on at 12:00 on March 2, 2016, the clock says 10:00 and March 2, 2016 (the date is not lost).

  Laptop works well when on battery (without adapter).
  I have WIN 8 is installed.

  RTC battery low message is displayed after the laptop is off (no adapter) for a while... (a few days).

  Above mentioned laptop is NOT a pile of separate clock when back cover is removed (no battery is visible on the motherboard)...

  What to do in this case?

  Waiting for your response.
  Thank you very much!
  Ivan

  I would say that the RTC is low and that maybe it's the other side of the motherboard. Find and download the manual for your machine. All PCs have batteries for the CCF and to keep some of the BIOS settings. If it is not under an agreement of service of any kind, take it to a technician, you trust and let check. Otherwise repair by the company with which you have permission. The battery will be there somewhere. They can be painted, I saw that with some motherboards desktop.

• Satellite C855-1GQ: battery not: the adapter is connected

  Hello

  This is my first post here, I hope that someone can help me!
  I have a Toshiba Satellite C855 portable 1GQ.

  So, basically, I managed to break the end of the original charger (the part that plugs into the laptop) and stupidly tried a charger of similar connection to another device that has a yield lower than the Toshiba

  However when I plugged it it killed inside the laptop as well as the adapter battery (it was an old anyway). I have a new battery and a new charger adapter, but the battery won't charge.

  When I put the battery it worked fine for the laptop itself is not broken, the laptop says it's connected and charge but it loses all power until the battery is flat.

  The new charger adapter doesn't seem to work despite the fact that he tells me that it is with a pile of work. The specifications for the new card are the same as the original (I got a cheapish of ebay).

  Is there a fuse inside the laptop to be replaced when I foolishly used the adapter that I should not have? I have read many possible solutions on it but none seems to be specific to my problem. Perhaps the new adapter is not good enough?

  As I said, the new battery worked fine until it ran out of power, so the charger or something on the cell load.
  Any help would be appreciated!

  See you soon,.

  > Is there a fuse inside the laptop to be replaced when I foolishly used the adapter that I should not have?

  The use of false and not compatible adapter may damage the laptop's hardware (motherboard could be affected)
  Very important is the fact that the original AC adapter supports the 19V (v) output voltage and
  Output current 3. 42 a (Ampere).

  Use of the power adapter with different output voltage (not 19V) would affect the material.
  The use of the AC adapter with 19V voltage output, but different ampere value should not affect the material.

  (Value) of lower intensity< 3a)="" might="" not="" be="" good="" enough="" for="" battery="">
  But where the power adapter is compatible, I would test battery certainly another, new, fully compatible.

• Satellite P855 - 10G is low on battery power, even when it is off

  I bought the Toshiba Satellite P855 - 10G, but I m terrified because he is low on battery power, even when it is off...
  Anyone know how I can fix the problem?

  Best regards

  Access the BIOS and disable options like: wake-up on LAN and keyboard.
  In Toshiba HW Setup I should disable the USB Sleep and Charge feature as well

• RTC battery low - where is battery CMOS? C50 - B - 14 D

  I also get a message at startup and strangely in Windows, low battery RTC. The laptop will simply shut down.

  I suppose there is a fault or battery CMOS is actually dead. I removed the bottom to expose the jury and watched various tear downs, but still cannot locate the battery. I removed the main Board and the CMOS battery isn't here. Is there one on these units?

  It is a fairly new laptop and otherwise in good condition.

  Any help appreciated.

  Some models do not have an RTC battery, they rely on the main battery to keep the time.

• 'Bad RTC battery, check the CMOS' on Satellite Pro 6100

  Hello... I just got a Satellite Pro 6100 and when it is started I get an error message:

  RTC BATTERY BAD
  BAD CHECKSUM (CMOS)
  Check the system. Then press the [F1] key
  _

  I can still use the laptop for about 15 minutes, but then it crashes. I did some research and discovered that it is the power supply Board. But my laptop is out of warranty and the reminder is now officially over.

  Y at - there someone who can help me?
  Thank you

  Hi Liam

  Hmmm... I think it s not a Council but the battery of the CCF.
  Take a look in the user manual. There you should find something that exactly the message is displayed if the battery RTC (BIOS) is not charged.

  The RTC battery, you must connect the power adapter and should run the laptop for about 24 hours.
  After that the main battery has been charged, then the RTC battery starts to load.

  It will take a little longer.

• Qosmio X 70-B-103 - RTC battery is low

  So my laptop Qosmio X 70-B-103 on the last days have been stop, and it won't turn when I press the button.

  So I proceeded to remove and replace the rtc battery and eventually it worked, but at the start of the laptop, on the blue color screen, it says "RTC battery is low"... So my questions are, the rtc battery closes down and should I buy a new one?
  (I have the laptop for about 1 year)

  Thank you

  In my opinion the RTC battery should not be traded but at full load. Leave your laptop on the power adapter and leave it for about 24 hours.

• Help for Satellite Pro M10 RTC CMOS battery replacement

  I have a Toshiba Satellite Pro M10 PS630E-G206C-FR
  Removing the main battery causes a failure message from RTC battery from the beginning to the top and loss of CMOS date/time.
  I tried to charge my main battery in full and then leave the machine in charge while it is turned on (I said it is a method for the CMOS battery)-without any result.
  .
  My questions: do I have to replace the RTC battery (ie: is it refillable welded or a CR2032 battery shows or similar).
  If a specific type, the best source?
  And also, where it is (I'm comfortable with disassemble my laptop having replaced the LCD cable already)
  Thank you

  Hi David

  Do you need help? What you mean exactly, step by step disassembly procedure? Maintenance manuals are not public documents and I'm really interested if anyone can offer assistance to you.

  When you want to swap the portable RTC battery almost entire must be dismantled. Believe me that is not the procedure of 10 steps and to do something like this, you need the disassembly instructions. I recommend you to check how it will be service charges because that when they disassemble the laptop they can clean at the same time and the laptop will be as good as new.

  If you want to do it yourself, it is very important to use authorized by Toshiba replacement batteries or real. Battery wrong installation may cause a battery explosion, or other damage.

  Please be careful about this.
