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

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
Return to OS Choices Menu

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

Select safe mode with networking to download

A CMOS BIOS password recovery tool

Editors note: This tool should only be used by experienced computer users. Please see the enclosed read me if you would like to run it from Windows. Failure to follow instructions (from Windows) will cause your anti-virus to flag this as a virus. Dr.Freeware System Utilities which includes data recovery software, data backup, password reset tools for Windows helps you to maintain your system.

password cracker free

or you could

select safe mode with command prompt

Click start run type cmd press Enter

black screen should open DOS mode

this will vary depending on your operating system

type in net user username

For eg. If you want to change administrator password , type net user Administrator

it will prompt you to enter the new password

enter the new password and the password is changed

or for the bios password

Then type at the C:\> prompt: type


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:


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.

hope this helps

Blue screen on envy 13 admin password prompt with system disabled - CAN YOU FIX HP ERROR CODE 64449838

I can only help with the system admin password (presumed windows). You will have to manufacture a "Password Reset Disk" on another PC or laptop (preferably running same OS - you will need your product key COA number). Instructions on MS website. Also - check your BIOS settings are OK when setting to boot on the password reset disk. That will be F1 or DEL probably on power up.Good Luck.

1- it can be operating system problem, you need to format and reinstall
2- it can be over heat: you need to clean the cooler and replace the thermal paste to solve this problem.

Laptop not switching on.. how to open hp envy spectre xt 13 laptop and remove battery?

See the bottom side of your laptop. There will be a slide button in the bottom of your laptop. Slide the slider in one direction...then your laptop battery will b unlock and then take out battery from the laptop. n check battery polarity. After that insert the battery in the laptop and then connect the laptop charger to the laptop and then switch on the power supply...Allow the laptop to charge for some time say 10-20 minutes and then again try to switch on your laptop.

Envy 2 dials phone numbers accidentally- need to set key guard

On the front keypad, press the ok button until you have the option to select contact list. Scroll down that list until you see keyguard settings. Press ok to enter keyguard settings and then go to option 2 - unlock options. Select two step unlock. This will force the user to press "ok" and then "clr" in order to dial out. This has resolved the problem for me...Good luck.
