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

    don't waste your money on phone calls, they wont help you with this. if you have warranty then waste money on that but not on phone support there's nothing they can do.

Internal Battery? You mean the CMOS battery (silver battery about the size of a nickel that is on the motherboard)?

Never heard of any dependencies of the CMOS Battery and the screen. Are you talking about a laptop? On a laptop you would have to take the screen off in some cases to get to the CMOS battery on it's motherboard. So, if you're talking laptop, then either the LCD Cable to the screen is not in good, the LCD Inverter cables (sits under the screen and has 2 cables in it, one from the screen and one from the the motherboard) is not in good. Remove the cables and plug them back in. Put a piece of tape across where the cable plugs meet on the back of the LCD Screen. One other possibility is you might have broken the lcd cable or mishandled the lcd screen and it is going bad.

How to clear an unknown BIOS password.


<span><span>Clear using jumper (recommended)</span><br /> <p><b>Precaution:</b> When inside the computer please be sure you're aware of the potential damage that can be caused by <a href="http://www.computerhope.com/esd.htm">ESD</a>.<br /> <p><img src="jumper.jpg" />On the computer <a href="http://www.computerhope.com/help/mb.htm">motherboard</a> locate the BIOS clear / password <a href="http://www.computerhope.com/help/jumpers.htm">jumper or dipswitch</a> and change its position. This jumper is often labeled CLEAR, CLEAR CMOS, JCMOS1, CLR, CLRPWD, PASSWD, PASSWORD, PSWD or PWD as shown in the picture to the right. To change the jumper simply remove it from the two pins its currently on so that it covers the pin that is not covered. For example, in the picture to the right pins 1 and 2 are covered, you'd remove the jumper and put it on pins 2 and 3.<br /> <p>Once this jumper has been changed, turn on the computer and the password should be cleared. Once cleared, turn the computer off and return the jumper or dipswitch to its original position.<br /> <p>The location of the jumpers or dipswitches are dependent on the manufacturer of the computer and motherboard. However, below are some general ideas on where to find it. Remember that most motherboards could have dozens of different jumpers, make sure you're changing the CMOS jumper and not something else. If these general suggestions do not help refer to your motherboard / computer documentation or skip to the next step.<br /> <ol> <li><b>On the edge of the motherboard</b> - Most jumpers are located on the side of the motherboard for easy accessibility, verify by looking at all visible edges of the motherboard.</li> <li><b>By the CMOS battery</b> - Some manufactures will place the jumper to clear the CMOS / BIOS password by the actual <a href="http://www.computerhope.com/jargon/c/cmos.htm">CMOS</a> battery.</li> <li><b>By the processor</b> - Some manufactures will place the jumpers by the processor of the computer.</li> <li><b>Under the keyboard or bottom of laptop</b> - If you are working on a <a href="http://www.computerhope.com/jargon/l/laptop.htm">laptop computer</a> the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.</li> <li><b>Other visible location</b> - While it is possible that the jumpers / dipswitches may not be in a visible location, most manufactures try to make things easier by placing the jumpers / dipswitches in another visible location.</li></ol><span>Remove CMOS battery</span><br /> <p><img src="cmos.gif" />Removing the CMOS battery like the one shown in the picture to the right will cause the system to loose all CMOS settings including the password. To do this locate and remove the <a href="http://www.computerhope.com/help/cmos.htm">CMOS battery</a> on the<a href="http://www.computerhope.com/help/mb.htm">motherboard</a> for at least five-minutes. After this has been done put the battery back into the computer and turn it back on.<br /><span>Jump the CMOS solder beads</span><br /> <p>Older computers and especially older laptops don't have jumpers or dipswitches and require the user to jump a pair of solder beads on a circuit board. The identification and location of these solder beads can vary and if not available in computer documentation is only obtainable through the computer manufacturer.<br /> <p>If you've identified the solder beads they can be jumped by placing a flat-head screwdriver over the two beads and leaving it on those beads while turning on the computer. Once the computer has booted turn off the computer and then remove the screwdriver.<br /></span>

I have a Lenovo A3 series all in one desktop computer and it is not recognizing my password and I am locked out. I put myself on as administrator and the computer was turned off before I backed up the...



first make sure the caps lock if off/on whatever applies the password when you typed it in

Remove a small coin sized CMOS battery to store all BIOS settings along with the password. To reset the password, unplug the PC, open the cabinet and remove the CMOS battery for approx. 15-30 minutes and then put it back. It'll reset all BIOS settings

as well as the password and you'll need to re-enter all settings.

Under the keyboard or bottom of laptop - If you are working on a laptop computerthe location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.

If it fails, then try to remove the battery for at least one hour.

click start control panel Open User Accounts in Control Panel. On the Users tab, click the name of the user whose password you want to change, and then click Reset Password. In New password and Confirm new password, type the new password, and then click OK. Notes You can change passwords only for local computer accounts, such as guest, administrator, or accounts you create for your computer. You cannot change your network logon password in User Accounts. To change your own password, press CTRL ALT DELETE and then click Change Password

hope this helps

How do I take out the screen on my HP G71 -329WM laptop


I have a HP Pavilion zv6000 laptop and have replaced both the screen and the hinges, plus a few friends laptop screens all the same way. First remove the battery and unplug the laptop. To replace the screen you will need to to remove the hard drive and remove all the screws form the underside of the laptop to allow access to the underside of the keyboard as the connectors for the screen are under the bezel above the keyboard. Opening the lid all the way will make it easier to get under the keyboard t and bezel then disconnect the power, video signal, and wifi connectors. Might be 1 or 2 or 3 separate connectors. Carefully removed the rubber plugs from the front of the screen and stored them so you didn't loose them. Using a small screwdriver, remove the screws under the plugs. Using a flat screwdriver or small thin blade, carefully separate the bezel around the outside of the screen, it may be glued together so take care not to crack the plastic. At this point would can see the screen screwed in to the hinges and the back of the lid and what screws need to be removed. The wifi antenna is usually attached to both the screen and the lid via tape so take care when removing the screen. Place the new screen back and attach the hinges and connectors, making sure to place the wifi antenna back where it was located properly. At this point I plug in the laptop and verify the HP logo or POST screen appears whe I turn it on, showing that the connections are ok before unplugging and continuing to replace the remaining screws, hard drive and finally battery. Depending on how the bezel around the screen is attached, you might want to use double stick tape as the glue no longer holds the front and back together around the screen. Depending on how mechanical you are, figure between 30 and 60 minutes to replace the screen the first time.

Error 161 & 163 on ibm aptiva 2168-m62


try this one:

Errors 161, 192, 163.
All three of these errors are connected to the back up
battery.
To resolve this problem:
1. open memory flap on base of laptop (small philips
screwdriver required)
2. find the small connector with 1 black & 1 red wire
coming from it.
3. disconnect above connector and gently pull the
Red&black wires. The backup battery should just pull out
from under the casing.
4. get replacement battery. Either
a. call IBM spares (07900 247 490 in UK) and ask for FRU:
02K6502. UK price is about £8 + £15 delivery + VAT.
b. if comfortable with soldering iron: Carefully open the
packaging on the backup battery using a sharp knife.
Remove the solder tags from the battery (these are spot
welded so need to be cut/broken off). Buy a new CR2025
battery from any computer shop, jeweler, or camera shop.
Using electrical tape, insulate all round edge of battery
(see the one just removed). Solder the leads onto the new
battery - note polarity. Red wire to +, black wire to -.
Using more insulating tape, wrap battery so that all
exposed metal is covered.
5. put new battery into laptop (reverse steps 1-3)
6. start up computer, error 192 has gone, but still shows
161, 163. Select OK.
7. reset date & time, and OK
8. when screen shows 'O / I' restart laptop using on/off
switch at side.

How do i reset CMOS on kv8 pro? getting POST code 25 comp not booting up, tried replacing ribbon cable, also unplgged keyboard. HELP!!!


unplug your computer, then you will find a small battery on the motherboard, this is a small silver disk shape. you need to remove this by pressing the clip to its side, this lets it spring free. you then need to locate the cmos jumper. this is a 3 pin stand off with 2 pins already covered by a plastic sleeve. remove the sleeve and place it over the other two pins, wait a few seccons then put everythinbg back to the way it was. put the jumper back in its origional position and re-attach the battery making sure it is the right way up. plug in your system and give it a try.
