I dont remember power on password for hp nc4400


The power-on password prevents use of the computer until the password is entered. The
setup password prevents unauthorized changes to Computer Setup. To clear the
passwords, you must remove all power from the system board. If you do not know the
passwords, use the following procedure to clear the password:
1. Remove all battery packs.
2. Disconnect the AC power.
3. Remove the real-time clock battery.
4. Wait thirty minutes.
5. Reconnect the AC power. DO NOT INSTALL THE BATTERY!
6. Restart the computer. During Power-On Self Test (POST), a ? 162 System Options
not set? message appears.
7. Shut down the computer, then disconnect AC power again.
8. Replace the real-time clock battery.
9. Install the battery pack(s).
10. Reconnect the AC power.
11. Start the computer.
12.It should work....

How do i change bios settings on a laptop that wont let me passed the hdd password


BIOS passwords on a laptop would be especially tricky to override, especially on a laptop, you will have to take the laptop to a service provider for the specified laptop brand, and have them wipe/replace the chip that contains the password. Hope this helps.

When I turn on my Laptop the Dell Inspirer E1505 it says A Disk Read error occured Press Ctrl + Alt + Dell to restart then i restarted the computer i pressed F2 and the BIOS setting came up i went to...


It's asking you for a password to access the BIOS. You or someone entered a password to access the BOIS (setup screen). The original problem you're having is "Disk Read Error". If you have the CD's that came with your laptop, look for a Resource CD or any that has "Utilities and Diagnostics" under "Contents". This is a CD that you can boot from. Insert the CD and select <F12> on power on. Select boot from CD/DVD disk. If the laptop boots then your laptop is working but your hard disk drive or OS (Operating system software) is the problem.

My hdd lock pasward ,ask me to put user hdd pasward. and i forget it what can i do?


Unlocking a password protected harddisk During development of the Rockbox firmware, on several occations the harddisk has become locked, i.e. password protected. This results in the Archos displaying:
Part. Error
Pls Chck HD
We are still not 100% sure why it happened. Theories range from low-power conditions to accidental chip select failure. It has also happened for normal users, using the standard Archos-supplied firmware, although it was more frequent for us developers.
Note: None of us developers have experienced this problem since march 2002.
We do however know how to unlock the disk:
Windows/DOS unlock Note: This requires taking the Archos apart, which will void your warranty!
  1. Grab atapwd (written by Alex Mina)
  2. Create a bootable DOS floppy disk, and put atapwd.exe on it
  3. Remove the harddisk from your Archos and plug it into a laptop (or a standard PC, using a 3.5" => 2.5" IDE adapter)
  4. Boot from the floppy and run atapwd.exe
  5. Select the locked harddrive and press enter for the menu
  6. For Fujitsu disks: Choose "unlock with user password", then "disable with user password". The password is empty, so just press enter at the prompt.
  7. For Toshiba and Hitachi disks, if the above doesn't work: Choose "unlock with master password", then "disable with master password". The password is all spaces.
  8. Your disk is now unlocked. Shut down the computer and remove the disk.
Big thanks to Magnus Andersson for discovering the Fujitsu (lack of) user password!
There is also a program for win32, ArchosUnlock.exe, that creates a linux boot disk with the below mentioned patched isd200 driver.
Linux unlock For those of us using Linux, we have written an isd200 driver patch for unlocking the disk. This modified driver will automatically unlock the disk when you connect your Archos via USB, so you don't have to do anything special. Apply the patch to a 2.4.18 linux kernel tree.
Still locked? If the above suggestions don't work, here's some background info about the disk lock feature:
The disk lock is a built-in security feature in the disk. It is part of the ATA specification, and thus not specific to any brand or device.
A disk always has two passwords: A User password and a Master password. Most disks support a Master Password Revision Code, which can tell you if the Master password has been changed, or it it still the factory default. The revision code is word 92 in the IDENTIFY response. A value of 0xFFFE means the Master password is unchanged.
A disk can be locked in two modes: High security mode or Maximum security mode. Bit 8 in word 128 of the IDENTIFY response tell you which mode your disk is in: 0 = High, 1 = Maximum.
In High security mode, you can unlock the disk with either the user or master password, using the "SECURITY UNLOCK DEVICE" ATA command. There is an attempt limit, normally set to 5, after which you must power cycle or hard-reset the disk before you can attempt again.
In Maximum security mode, you cannot unlock the disk! The only way to get the disk back to a usable state is to issue the SECURITY ERASE PREPARE command, immediately followed by SECURITY ERASE UNIT. The SECURITY ERASE UNIT command requires the Master password and will completely erase all data on the disk. The operation is rather slow, expect half an hour or more for big disks. (Word 89 in the IDENTIFY response indicates how long the operation will take.)

Disc read error occoured


Hi,

This can occur as a result of any unreadable drive that is in your boot sequence not reading. Remove all media from the machine(CD, DVD, Memory Card, Flash Drive, Floppy Disk, Printer with memory card slots), then try booting again.

If that doesn't work, chances are your hard drive is damaged. It may only be minor logical damage or could be serious hardware damage. That is more difficult to assess via subjective analysis but could be sent to a pro for assessment if you have files you require on the drive which are not backed up.

If this is the case and you do not have anything important on the drive or if you have your files backed up on a second source simply replace the drive and re-install your operating system, then restore the backed up files and move forward.

If you require any additional info or advice, just ask
