  • 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.

  • 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.

  • 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.


    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

  • Pavilion 15 - e034tx: battery replacement problem


    I need a replacement for the battery, as the battery is not able to take even 10% fee.

    I live in Kolkata, Bengal, India... I talked with people in the HP Service Center and they told me to get a new battery.

    My laptop is a HP Pavilion e034tx 15, it has a battery of 6 cells PI06, 10.8 v - 47Whr. I enclose a snapshot below:

    I can't find this battery in all retail HP here in Calcutta, and the strange thing is, the Service Center HP told me that the new battery will cost Rs 6800/-(along with additional taxes) which is about US $102!

    But a strange thing is that, in the accessories page HP, the battery proposed for my laptop is the HP VI04, which does not yet fit in my laptop!

    Now, I'm kind of confused that I need the battery immediately, in order to continue my studies... What should I do? Help, please

    Buy it here:

    There are also several batteries "compatible" on eBay India for less than 2000 rupees:

    If you need something in a hurry, a compatible battery can be good for you. I prefer the batteries authentic, but not sure they're worth 3 times the money.

  • Pavilion zv5000: cmos battery location

    I recently did a clean install of win7 XP and since then have had to reset the boot sequence.  After some research, I realized that the cmos was not keeping date/time, etc.  After you start through the process of recovery of the win7 os works find.  I downloaded the manual but have not been able to positively locate the cmos under the keyboard battery.  My laptop is a HP Pavilion zv5000 or zv5260us.  I would like advice as to its location, if it is welded to the and is replaceable?

    Also, I would like to update the primary RAM of 256 to 1 GB.  The secondary was already running 1 GB.  Is this a possible upgrade?

    Any help would be appreciated.


    In fact, I used to own a very close model of one and can vouch that it can use 2 GB of DDR 800 SO - DIMM (first gen DDR). There is a slot under a door over there and the other is under the keyboard, which is not too difficult to remove it. Here is the Manual:


    I don't see anything in the manual about the RTC battery or its location which leads me to believe it is soldered to the motherboard.

  • 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.
