Only if you can manage....shut down the system. Open the covers, locate the CMOS battery & keep the battery away for 2 minutes,]

Which operating system ???
CMOS (Complementary metal oxide semiconductor) refers to the battery-powered, semi-conductor chip located on an HP computer's motherboard.
It is where the BIOS stores important information regarding the PC's system configuration. CMOS is required for an HP laptop and its hardware to run stably.

Sometimes, however, it is necessary to clear CMOS, such as if you lose your BIOS password or your BIOS is corrupted.
Clearing CMOS on HP laptops varies depending upon the model, but for a lot of laptops, the process simply requires removing the battery for a short period of time.
Power down your HP laptop. Remove the AC adapter and any other peripheral devices. Turn over the computer so that the bottom side is facing up.
Ground yourself, either by touching a piece of unpainted metal or by wearing an anti-static wrist-strap.

Locate the battery. This will vary depending on your laptop's model, but it is usually located on the back, near the rear of the laptop.
Review your laptop's documentation to find the battery, if needed.
Many newer models require that you remove the battery by releasing or holding down one or two latches, then gently pulling the battery out.
Some models may instead require that you unscrew the battery from its compartment.

Leave the battery out of the compartment for at least 30 minutes.
Do not attempt to turn on the computer and do not touch the battery within that time.
Some HP laptops may require you leave out the battery longer to clear CMOS, others might take only 10 to 15 minutes to reset.
Ground yourself, then put the battery back into the HP laptop.
Snap the battery latch into place or screw the cover back on, if necessary.
Removing a Bios - CMOS Password

Disable Fingerprint on an HP Laptop
Many HP laptops include a fingerprint scanner to enhance the security of your computer.
When the fingerprint scanner is enabled, the computer requires a fingerprint scan to log onto Windows.
Disable the fingerprint scanner if you do not need or want this feature.
With the fingerprint scanner disabled, you can log on to Windows using a password.
You can enable the fingerprint scanner anytime you need to.
Access the Device Manager on your computer.
Select "Control Panel" from your computer's Start menu.
Click "Hardware and Sound" and then click "Device Manager."

Find "Personal identification devices" in the "Device Manager" list.
Click the "+" sign next to "Personal identification devices."
This opens a list of all of your devices.
Click on "Validity Sensor."
Select the "Driver" tab at the top of the properties window and click "Disable" to disable your fingerprint scanner.
The button changes to "Enable" and you can enable the fingerprint scanner at any time.
Click "OK" to exit out of the window.

IF you are using something that has a touch pad on it, chances are that you are hitting the pad while typing and the cursor jumps to the wrong spot and lays down letters. I have also see this happen with shortcuts too. Try covering the touchpad with cardboard and typing.

yes you can go to hp touch smart open go to definitions and see display light and afther will see a rainbow in th e screen and is just touch the desired colour and that it thanks and good luck

A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
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.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

Pl switch the machine off and put 2-3 pounds of pressure with your palm on the keyboard closer to the spacebar.. this will fix it..
it is caused by the weakening of the adhesive of the wires below the keyboard.
Long term option - get the keyboard opened by the an professional and cleaned properly..and fixed back neatly...
