Fujitsu Seimens Laptop V2030. I have removed the 2030 disk shaped cmos back up battery placed under sticky tape and replaced with new. The computer will now not boot up. I have power to the fan but no screen. is there a lock that I have to remove through the keyboard settings?

    I replaced the cmos battery because the time and date bios settings etc were having to be reset. I have a lot of computer knowledge so I know what I am doing when replacing the cmos battery. I have never known this to happen before and was wondering if there is a built in lock that is released when a sequence of keys are pressed. I have tried speaking to Fujitsu who have a premium line call rate with an 090 telephone number. unfortunately my telephone will not accept 090 telephone numbers due to a vast amount of these calls in the past.

    Why did you replace the battery in the first place?
    The job of the battery is to hold the Bios settings when the computer is disconnected from the power source (like a power outage or the cable is unplugged from the wall)- in other words: it should even boot up without a battery in place.
    I know it sounds stupid, but is the battery polarization correct?
    Otherwise I can only think of o problem with your motherboard, if you don't even make it to the Bios.
    Did you try another monitor to eliminate a failure of that?

Changing this shouldn't cause or harm it at all. except if you change it the wrong way it could burn the bios chip's internal blocks.

1. remove the battery, + big battery + ac charger
and wait 15 minutes, then boot.

2. try booting without the cmos battery

3. try swapping the memory

why did u change it in the first place?

    it will still work even without a bios battery in place the only thing is it wont save the correct time, so I realy think something else happened like a shortage caused by a screw or something...or the wrong side battery was fitted

How to reset bios on compaq v2000 laptop


Remove A Cmos Battery From A Compaq V2000 Laptop

The Complementary Metal-Oxide Semiconductor (CMOS) in a computer is responsible for storing hardware settings and time on your computer. The CMOS is powered by a small battery and is able to store information whether your computer is turned on or off. While the standard CMOS battery lasts for up to ten years, you may need to replace your CMOS sooner than that. If you password your BIOS and forget the password or need to reset your configuration back to the default, you can remove the CMOS and re-insert or replace it.

Instructions
1. Unplug the computer from the wall outlet and unplug the AC adapter from the computer.

2. Turn your Compaq Presario V2000 face down and slide the battery release latch to the left to disengage the battery from its position. Remove the battery.

3. Unscrew the screws over the hard drive cover, which is located in the lower right corner of the laptop if your laptop is placed with the battery away from you. Lift the hard drive tab, located on the left side of the hard drive, and slide the hard drive to the left to remove it from the computer.

4. Unscrew the single screw located directly under the optical CD/DVD drive. Insert a very thin item, such as a paper clip or pin, into the hole located on the optical drive to open it. Slide your optical drive out of its tray to remove it.

5. Remove the two screws located on the switch cover, which is directly under the battery. Turn the computer right-side up and open it as wide as it will go. Use a flat tipped screwdriver to lift up the switch cover that is directly above the "F1," "F5," "F11" and "Insert" keys.

6. Unscrew the four screws that hold the keyboard in place. These screws are are located in the upper right corner of the computer under the switch cover that you just removed. Lift the keyboard up and slide it forward until it rests on the palm rest. Unplug the zif connector, which is located directly above the palm rest, to disconnect the keyboard. Lift the keyboard up and out of the laptop.

7. Turn the computer upside down again and remove the memory modules by unscrewing the two screws over the memory compartment located directly below the battery slot. Unclip the two clips located on each side of the memory module to release it from its slot and slide it out of the computer.

8. Unscrew the two screws on the PCI cover directly beneath the memory module. Disconnect the two wireless antennas above the card. Spread the two clips securing the mini PCI card into place and lift the card up and out at a 45-degree angle away from you.

9. Flip the laptop back up on its right side and disconnect the display cable located in the upper left corner above the keyboard area underneath the switch cover you removed earlier. Then remove the two pieces of tape in the upper right corner that hold the wireless antenna in place. Remove the two clips located beneath the tape pieces. Unscrew the two screws on the upper left corner and the two in the upper right corner that hold the display into place. Remove the display assembly.

10. Turn the computer back upside down and remove the remaining 19 screws. Lift the base enclosure straight up out of its place.

11. Locate the CMOS battery, a small circular object, and lift it up out of its place. Leave it out for five minutes and reinsert it to reset your settings. Re-assemble the computer without the battery and plug it into the wall.

My n6410 hard drive is password locked,but i dont know the password


In order to unlock your hard disk drive. You have to open your laptop and look for the cmos battery, cmos battery is a small circle dry cell and its number is CR2032. The cmos battery are responsible for holding the bios settings like the system date and time. The purpose of removing the battery is to clear the settings you save in your bios/cmos settings, just remove from its base and put i back after 10 seconds. With this procedure it will unlock your hard disk drive and now you access your computer. The problem here right now is the opening of your computer. You have to be careful while opening your computer you might break the casing or damage some parts. Have a nice day.

I need instructions on replacing cmos battery? Where is it located on the hp compaq nc 6220 laptop


if you see the motherboard on the laptop, it is a Circle shaped battery which is on the lower right side of the processor normally. To replace CMOS, make sure you turn off the pc, remove the cables the battery, remove the screws at the back, remove the hard drive, remove the optical drive, remove the fan , remove the heat sink, remove the keyboard plate, and then if the motherboard is displayed, remove the CMOS by pushing the eject button right beside the CMOS. Insert it the way you lift the battery in a counter situation. Then placed the parts on the descending manner that I enumerated earlier.

How can i locate and change my cmos battery for laptop fujitsu siemens v2010 pro



The above post sounds simple it is Not, the COMS battery in a Fujitsu V2010 is located just to the left side of the left hand mouse button,( just about where it says AMILO Pro) (under the top cover)
(All power off battery out)
To get at it you remove all the base cover screws including the four on the back edge.
Turn the laptop over and remove the power buttons plastic strip by levering upwards between the gaps that are to the left of the Num Lock key and the right of the Esc key, (use a very thin screwdriver) or slide a screwdriver between the Num lock key and cover leaver upwards, then do the same at the Esc key side, the four retaining lugs are left and right of the cover.
The screen should be laid flat as you do this or you will rip off the keys.
Unscrew the wrap over bracket (right of screen) that holds down a thin black cable.
Pull upwards (carefully) the three connectors in the two recesses below it. (Two in left recess one in right recess)
The cables in the right recess are held down with a strip of black tape remove it and remove the cable from the retaining lugs.
Remove the keyboard screw and push slightly towards the screen to get at the retaining strap and remove the strap by levering the lugs upwards on both sides, put the keyboard to one side.
The wireless card cable is slotted in a channel lift it out. Then unclip and lift out the card still attached to the cable.
Remove the left and right screen screws and carefully lift upwards and remove the screen with the wireless card still attached, put the screen to one side,
Remove the four RAM cover screws and lift off the cover put to one side.
There are 3 tiny screws at the back that are just under the screen location remove them, the last screw is just under the key board in a deep recess remove it.
Finally lift the top cover up slightly and push slightly towards the screens location as the COMS battery is attached to the mother board at front left. (Unplug it)
Work very carefully making sure you do not miss any screws, if it will not come off you have missed something. CHECK.
The cover should come off without any resistance.
The screws are different sizes apart from the base cover screws,( TIP) tape a wide strip of cello tape sticky side up on your work bench and group the screws on it marking with felt tip where the were located.
The wires on the battery are RED and BLACK
Leaver out the battery it’s held firmly by a sticky pad and change it (the wires come attached to the new battery. (Battery VARTA CR2032 3v 0405)
I am writing this from memory but I don’t think I have missed anything, remember if it will not move do not force it LOOK. (Something’s can be done not exactly in the order I have tried to explain it)
Replacement is the reverse of removal.
One site I was looking at wanted £45 for changing a keyboard, that’s a real rip off.
Hope this helps if in doubt take it to a shop.
Best of luck. teastheword find me on E Bay.

Need to bypass/clear the Compaq Presario 1200 bios password


Try removing the main battery, then open the case. Under the keyboard and close to the CMOS chip, you may find a reset buttom or jumper. Alternativelly, you may remove its small round-shape battery for half an hour or so. This would return CMOS features to default. Fix power supply again and restart, normally the BIOS should stop asking for a password
