The easiest way to do this is to remove the keyboard and look for the bios battery. Unplug the laptop and remove the normal battery and then remove the bios battery for about 10 mins. Replace the Bios battery, replace the normal battery, plug the laptop back in and the password should be gone.

Forgot pass word on my compaq pc


Which password you are referring to, There are two types of password.
1. Windows Password
2. BIOS Password.

If you are referring to Windows Password, I Suggest you to Reinstall the Operating System to resolve the issue

Or if it is BIOS Password you need to Disassemble the laptop and remove RTC Battery which looks like a money penny and reinstall after few minutes. this will help you.
Hope this helps.

Suddenly there is no sound in the speaker but headphone works fine..laptop is Lenovo B575


If the head phone jack works its more likely to be the problem, if you use the headphone jack a lot the connections inside it can get worn or bent out of shape--engaging the headphone jack should shut the speakers in the unit off.

Other possible reason is a bad speaker or connections.

`What is the password for phoneix bios setup utility


Toshiba has been leading the pack in this kind of security for years now. The only way to reset the BIOS password on THAT laptop, is to send it back to Toshiba.


Now, do you know what Toshiba will do next? Toshiba will ONLY send the laptop back to the current registered owner.



So, here is what you do. If the previous owner registered their laptop with Toshiba,

THEY have to transfer the ownership to you... you can't do that. THEN, you can send it back to Toshiba to have the BIOS password cleared.

THEN Toshiba will send it back, repaired, to you.

You cannot jump the BIOS chip, since the password is not stored there, but rather it is stored in an EPROM chip that does not require electricity.

So you cannot even remove the CMOS battery to clear the password.


You cannot use a special program and a floppy disc, because that Toshiba will not access the floppy disc before it accesses the BIOS... and since you will hit the password first, you can't access that software to try to clear the password


or you might try


restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer

Reboot the computer As the computer is booting repeatadly press the F8 key as the computer is booting


If done properly the user should get to a screen similar to the below screen.

Select the option for Safe mode command prompt only

Windows Advanced Options Menu
Please select an option:

Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt

Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)
Debugging Mode

Start Windows Normally
Reboot
Return to OS Choices Menu


Use the up and down arrow keys to move the highlight to your choice.


select safe mode with command prompt


Then type at the C:\> prompt: type

DEBUG

and hit Enter. You'll see a dash (-) at the DEBUG prompt. Now type:

o 70 2e

which will show as -o 70 2e at the DEBUG prompt. Hit Enter. Then type:

o 71 ff

and hit Enter. Finally type:

Q

and hit Enter one last time to quit DEBUG back to the C:\> prompt.
Now you're ready to reboot your PC, and press the appropriate key or key
combo (look it up in your motherboard manual if you don't know it) to access
your BIOS Setup.


Youll notice the password is gone.


if this fails try typing


At command prompt type debug
you will get a - prompt where you can type the following (<enter> means press enter, not type enter*)

A <ENTER>
MOV AX,0 <ENTER>
MOV AX,CX <ENTER>
OUT 70,AL <ENTER>

My pc automatically get start on plug on .and then it suggest me to press F1 to Continue. when I do this it takes incorrect date and time how to restrict it.I want to start it with start button on cabinet


There can be many reasons...
  • Your BIOS setting is not correct.
  • CMOS battery is down(Most probably).
  • both
You can open the BIOS setting page by pressing keys like DEL, F10, etc. depending on your system's manufacturer at computer startup(post screen). There are lots of wakeup options check them properly.
One of the option is "Restore last state of power Button on failure" which can turn on your computer without touching the power button. you should check these options.


And it suggest you to press F1 because your system's date/time is not configured properly. You can also set Time/date in BIOS also.
If your BIOS Battery(CMOS) is not weak or dead then after setting these values your computer should start properly.
And if your BIOS battery is dead then all the settings will be lost(date/time etc) after a restart and you will face same problem again...

Try changing the Power-button option and Date/Time in BIOS and see if problem persist....if yes then you have to change COMS battery that is on your Motherboard.
