Dear Jeremy,
BEST PRACTICE: ALWAYS WEAR AN ANTI-STATIC WRIST-BAND WHEN FIDDLING IN THE BOX!
The human body can store up to 50,000 volts static electricity which is more than enough to fry components. MAKE SURE YOU ARE EARTHED! (1.): Switch power off at wall. Leave plugs in - (this will ensure that the computer is 'earthed'. (2.):Open box. (3.):Connect anti-static wrist-band alligator clip to bare metal frame of box - a bare screw head will do if you can not see any uncoated metal in the box). The password jumper has 3x sockets in a row. (4.):Move jumper plug to other 2x sockets to reset - (blank) - password. (5.): Remove anti-static clip. (6.): Close box cover. (7.): Power-on at wall. (8.): Reboot. If you want to reset a new Password, repeat above steps & move jumper-plug to other 2 sockets...when you reboot, you will be asked to enter new password. I hope that this helps - 'b'ye - Bruce.

SOURCE: d530 CMT minttower power problem

Hi, from your description it appears your power supply is ok.

Remove your RAM chips, clean everything with a soft brush or a can of compressede air [from computer store] Reinstall the RAM making sure it is seated firmly.

If this does not solve the problem, Are you using 1 or 2 RAM sticks? if 2 then remove them again and swap them around.

stick one in dimm2 and stick 2 in dimm 1.

If you only have one stick then beg or borrow another stick and try it. If all fails you may have developed a mobo problem.

SOURCE: Clear cmos Dell dimension 3000. It don't have pin or jumper

Open the case and locate the CMOS battery. Just nest to it should be a button or jumper. Press the button or remove the jumper, then start the machine.

If it's a jumper, turn the machine off once more and replace the jumper before continuing.

SOURCE: Dell Dimension 5100 will not power up. Was

Have you checked your monitor? Try your monitor on another PC and check it is OK. Once you change the MB battery you effectively "Kill" the PC, as all the settings in the BIOS are removed and must be reprogrammed. You must enter the BIOS, and select "Default" setup and then reboot, you must do this regardless of what else is done first.(A bit hard when you can't see anything" You say... "tried different power switch and ribbon cable connector" (sic) exactly what "Ribbon cable/Power switch"? Anyway as said check monitor, if it is OK, we will proceed from there, then, you must check your video card, test it in another machine, if possible, to see if thats OK, if it is OK, then it is now likely that you may have a Mother board problem. If you can, try another Video card to see if you get Video on screen. see we need to establish "Known Good" items, once we know whats what, we can then go on. Now if any of these things tested are faulty, Monitor, Video card, obviously replace them, however IF they are NOT faulty, as related it may be the Motherboard, Remove the RAM, and see if anything is on screen? If yes, replace RAM, If still NO, then take any cards out, and check, if then OK, replace cards one by one until you get to the one that stops it, there is your problem, replace it. All we are trying to do is get anything on the screen, if we do, then you must redo the BIOS, as related before. Now if you get it going it still may not boot through to windows desktop, if this is the case, after you boot press F8 and select safe mode, when you get asked if you want safe mode or system restore, choose system restore and choose a date before you had a problem that should get you back. You just have to logically work through, until you find the faulty "bit" and replace it.

My system is password locked and I cannot remember the bios password


You cannot bypass the password security yourself. If you could there would be no point in having password security on all our devices.

Were is cmos battery located


removing cmos battery doesnt work no matter how long you leave cmos battery out been there done that , you have to locate cmos jumper on motherboard , remove main battery & memory cards , peel back clearish foil on motherboard near where memory cards install , should see jumper points on motherboard , take bread tie touch jumper contact leave main battery out stand up like book plug in power adapter , and turn on only until boot screen then shut-off , install memory card , remove jumper and try starting laptop , if it hasnt cleared password , remove memory cards and try jumping it again

Forgot password




how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard some motherboards cmos batteries are soldered in

Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased
or if using XP

Restart your computer during the boot process tap the f8 button three times this will boot into safe mode where the only things working will be your mouse and keyboard enabling you to attempt to repair your computer Advanced Boot Options screen appears.

Select the Safe Mode option using the up and down arrow keys, then press the ENTER key. Choose "Windows XP Home/Professional", depending on the version of the operating system.

Press ENTER. Shortly, the welcome screen should show.
Log in as "Administrator". Click Yes to not use System Restore Mode.


Click the Start button. Choose Run and type in "control user passwords" (without the quotes). Click OK.


Select the "Administrator" user. Click Change my password. Enter a new password in the corresponding text boxes. Click OK. Write this password down and store it in a secure place
Close the User Accounts window and restart Windows.
hope it helps

I forgot my bios password, i want to reset my bios password


A. By Removing the CMOS Battery:

cmos_battery.jpg Almost all motherboards use 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.
If it fails, then try to remove the battery for at least one hour.
B. By Using the Motherboard Jumper:
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

My leptop ibm thinkpad A22P is lock with bios password not opned my leptop


Answer: If you encounter a password prompt at boot or the BIOS / CMOS setup is locked as shown below and you do not know the password you will need to clear the BIOS password using the suggestions listed below.

cmospass.jpg Generic BIOS / CMOS passwords

Try using generic CMOS passwords. A complete listing of these passwords can be found on document CH000451.
Use a BIOS password utility

There are utilities designed to help bypass CMOS passwords. An example of a great utility to decrypt / bypass BIOS passwords is the PC BIOS Security and Maintenance toolkit, which is available by clicking here.
Clear using jumper (recommended)

Precaution: When inside the computer please be sure you're aware of the potential damage that can be caused by ESD.

jumper.jpgOn the computer motherboard locate the BIOS clear / password jumper or dipswitch 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.

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.

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.

  1. On the edge of the motherboard - Most jumpers are located on the side of the motherboard for easy accessibility, verify by looking at all visible edges of the motherboard.
  2. By the CMOS battery - Some manufactures will place the jumper to clear the CMOS / BIOS password by the actual CMOS battery.
  3. By the processor - Some manufactures will place the jumpers by the processor of the computer.
  4. Under the keyboard or bottom of laptop - If you are working on a laptop computer 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.
  5. Other visible location - 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.
Remove CMOS battery

cmos.gifRemoving 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 CMOS battery on the motherboard for at least five-minutes. After this has been done put the battery back into the computer and turn it back on.
Jump the CMOS solder beads

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.

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.

My kids setup a bios password on my new HP laptop and they cant remember it. How do i remove the password without knowing the previous that was set by them. Please guys help me.


The only way to do this is to reset the CMOS/BIOS memory.

  1. Remove the back cover of your laptop to "reveal" motherboard.
  2. Make a way so that you can see the a bigger portion of the motherboard ESPECIALLY the small lithium battery powering the CMOS chip.
  3. If this battery is reachable, remove it in place.
  4. After 3 minutes or more, place the battery back.
  5. Place the covers back and power on your laptop.
  6. The bios password now should be removed since the content of the CMOS memory is cleared.

How can I reset password for Bios Phoenix? the problem is that i can't run windows also


Try this, this is called "Backdoor BIOS Passwords" (manufacturers use these passwords for testing and maintenance.)

Reported Phoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, and PHOENIX.

OR

Try removing your CMOS Battery. (Note that all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.)
Remove this battery along with the power cable from the power supply. Hold down the power button to fully discharge the system. Wait 2-3 minutes then reinstall the battery and plug in your system.

OR

Some motherboards have a 3 pin jumper by the battery. Lets say that the jumper is on pins 2 and 3. Remove the jumper while the machine is OFF and place onto pins 1 and 2. Power on your machine for a minute. (Note: Your system will not POST). Shutdown your machine and put the jumper back to pins 2 and 3. Power on your machine

I forgot BIOS password for SONY PCG-GRX520


The best way for the Sony is to remove the cmos battery for at least 30 minutes. Remove the main laptop battery and leave it out. Make sure the power adapter is not attached. The cmos battery can be reached after removing the keyboard and is attached to the motherboard vis a small cable. If you have a "jumper" that come equipped on hard drives to jump the pins on the back, you can "short" the pin connections on the cmos battery socket, power the laptop up using the ac adapter and letting the computer go through the bootup process. When this happens power the laptop back down, take the jumper off and replace the cmos battery. Power back on with just the ac adapter and boot the computer. If the laptop still askes for a bios password just hit enter and it should allow you to log in. Once in go into the bios and reset the date and time. Once that is done power down and replace the main battery. Reboot the laptop and let Windows load.

Emachine t5026 does not appear to have any power, when you unplug the power cable from unit the ehaust fans breifly turn on, and light on mother board flickers, other than that sign of power Tried putting...


Unplug every thing such as the CD/DVD trays, Hard Drive, take out any dial-up modems, network cards, video cards, etc. unplug even the mouse and keyboard. Try powering on agan. If the computer seems to work, then power back off and plug in one device then power on computer. Keep doing that until you find the bad device preventing the computer from turning on.

If that doesnt work then carefully remove the RAM completely then carefully replace the RAM. Now with on the Dynex power supply plugged in to the motherboard, try again. If still nothing, remove the RAM and try again. If it still does the same thing, then the motherboard is dead and needs replaced. If instead you get a series of beeps then the problem MAY be bad RAM. Try different RAM. If that doesnt help. The only thing left is taking out the CMOS battery, It is the coin shaped battery on the motherboard. Take it out and wait 20 seconds then put it back. I doubt it is the CMOS battery, but at this point it is worth a shot.
