• Location of battery CMOS C50 - b satellite

  Can someone help me locate the CMOS battery in a C50 - B?

  I have not been able to find and that you can find no source of information on the internet until now. Is anyone else having the same problem? Whenever I stop, the clock loses its parameters as well as the date. The system tells me that the battery is almost discharged. SO it must be there somewhere and none of the tear down videos online presents helpful tips on its location.

  I hope someone out there can help.

  Here is a video of the tear down process of your laptop. The CMOS battery is round, flat and silver. It's almost close to the HARD drive and the CPU fan.

  Hello

  Please I need to know the reference of my TOSHIBA Satellite A100-307 model (PSAA9E-11f03XFR) battery to replace because I lost.

  Generally, all compatible parts can be ordered from the Toshiba ASP in your country.
  But to be honest I do not know if you will be able to order a battery RTC m

  However, it s advisable to communicate with ASP guys and asking for.

• 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 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.

• RTC battery is low or CMOS incompatible chksum on a new Tecra M4?

  Hello

  I bought my Tecra M4 in November, making it relatively new.

  Since then, I got the following message to the ignition on four occasions:

  RTC battery is low or CMOS checksum is inconsistent *.
  Press [F1] to set Date/time.

  Why is it that happens on a new laptop? And with relatively long intervals (4-6 weeks)?

  Is that what I can do to check for hardware errors?

  I prefer not having to send to my computer right now (reviews of spring to come to the top and from one month summer session).

  Any help/ideas are appreciated.

  Kind regards
  Thor

  Hi Thor

  As far as I know is not a hardware problem. Connect the camera to the power adapter and leave it for 20 to 24 hours.
  I hope you use it very often and the battery can be charged at all times.

• 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.

  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 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.

  Normally, the RTC battery in these models are rechargeable.
  If not already done, please leave the unit on for the night (not disable, not extended, not sleep - but ON) and see if the problem is resolved.

  I think the accusation-description/also the RTC battery is mentioned in your user manual.

  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?

  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. ;)

• 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!

  Hello

  Why you want to replace it
  This battery is accessible
  The RTC battery, you need to connect the AC adapter to the laptop.
  The main battery must be inserted too and the laptop should work during hours 20.24.

  In any case, as far as I know it s an Ion of Lithium battery 3V and 14mAh RTC

• Satellite C855 - low RTC battery

  Bought a brand new Satellite C855 7 months, now get a RTC battery low warning, every time I start, have to reset the date and time. The laptop battery says fully charged, but if I unplug the portable charger will turn off.

  > The laptop battery says fully charged, but if I unplug the portable charger will turn off.

  This means that the main battery is empty and is probably damaged.
  Empty main battery would affect the RTC battery too. So I think that you need to replace the main battery first and then the RTC battery for a longer period of time while the mobile computer is turned on.

  The laptop seems to be covered by the warranty (if its 7 months) so the battery must be replaced in warranty conditions.

• Satellite Pro M40 - where battery CMOS

  Hello

  Could someone please tell me where the CMOS battery on an M40 225, also do you know what it takes?

  Thank you

  Hello

  Unfortunately I can't tell exactly where is the CMOS battery but it s certainly somewhere on the motherboard and the whole notebook must be disassembled to gain access to the battery of the bios.
  For the most part this procedure of disassembly is very delicate and must be made in the right order.

  But may I ask what's wrong with the battery CMOS?
  Is it empty? Have you tried to load?
  Usually, you could reload the CMOS battery very easily. The laptop must be turned on and must be connected to the power adapter for 20-24 hours.
  The laptop has to run all the time!

  In any case, I found an interesting page on ['How to disassemble a Sat M45' | http://www.irisvista.com/tech/laptops/ToshibaM45/Satellite_M45_disassembly_1.htm]
  The M45 is very similar to the portable M40.

  But note; everything you do is at your own risk! I have

  PS: The CMOS battery can be ordered from the ASP in your country!

  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.
