Re: laptop monitor

You probably need to increase the brightness on the laptop monitor. Your question is listed in a generic fashion so I give you the specific key combination, however, you typically hold down the Fn key that use hit the F7 (brightness up) or F8 key (brightness down). Let us know if you have any other questions and please don?t forget to rate this posting.

Brighten screen

Toughbook is a type of laptop computer marketed by Panasonic Corp.

The durable exterior makes it ideal for use in the military, government, hospitals and EMS systems.

The backlit keyboard is an accessory that can be added for convenience.

Check Power

Check the Toughbook to see if the power is on. Inspect the power cables to ensure they are intact.

View the available battery life on the screen of the Toughbook.

If the Toughbook is not receiving an adequate amount of power, the backlighting may not operate properly.

Optical Sensor

Remove anything that is obstructing the optical sensor.

The optical sensor is on the top right side of the keyboard.

The sensor reacts to light to determine if the backlighting should be turned on or off.

If there is anything obstructing the sensor, the backlighting will not work.

Wipe the sensor with a dry cloth to remove any dirt or dust that may be obstructing the sensor.

Connector Ports

Check the cables in the connection port to ensure the cables are securely inserted in each port. The connector ports that allow the keyboard to communicate with the LCD screen are on the left side of the keyboard and screen.

The keyboard cannot operate properly without solid connections, which are made with a USB and a function cable.

FN Button

Press the "FN" and "F12" buttons to brighten the back light.

The back light may be operating properly but you may be unable to see the light if it is too dim.

Pressing these buttons together will brighten the back light by at least four levels.


Place your hand on the bottom of the keyboard. If the keyboard feels hot to the touch, the keyboard probably has entered a protective sleep mode.

The Toughbook will go into protective sleep when internal temperatures reach a dangerous level.

When this happens, allow the computer to remain shut down for a while in order to cool down before it will begin functioning properly.

When the computer feels cool to the touch, it is safe to use.

This typically takes 15 to 20 minutes.

Hope this helps

My laptop HP Pavillion ZV6000, battery started decreasing and wouldn't charge when the ac adapter was connected. I purchased another ac adapter thinking that was my problem. It didn't work. Now I have...

As others have said, the most common fault with the ZV series is the power socket. However, you mentioned the Lightning Bolt. This indicates that the battery is being charged and it should go out as soon as the battery is fully charged.

If the Lightning Bolt flashes on and off regularly, especially when the power cable is moved, then the socket is at fault and needs replacing.

You can check to see if the battery is receiving a charge by doing the following

1. Right Click the Desktop
2. Click Properties
3. Click the Screen Saver tab
4. Click the Power button
5. Click the Power Meter tab

This will tell you the computer's current power source and whether the battery is charging.

I have replaced several of these sockets on ZV5000s and I'm sure the 6000 will be similar. I would not recommend this job for anyone without technical knowledge, despite some of the websites that say you can do it yourself. You will need to strip the entire laptop down and all but remove the motherboard before the socket can be replaced.

Hope this helps

Battery problems

It should fix the problem, did you make sure you got the right battery(correct model number etc? like a genuine OEM battery).

If that doesnt fix it, go into your control panel, power settings, and select the battery option.. and check how your laptop uses the battery when its not plugged into AC power.

If that doesnt fix it, then contact HP, if its still under warrenty, it might be the AC terminal thats going bad, and might need the computer serviced. BTW how old is the computer?

HP Pavilion Laptop zv5000 wont power on. NOT power cord problem.

I think your motherboard has gone bad, even though you hear a fan working, its just on a hot wire on the motherboard.

Follow the steps below to determine whether the problem is related to the AC adapter or your notebook system board:
  1. Remove the battery and disconnect all external devices from the computer.
  2. Hold the Power button for several seconds, with all power sources removed. This drains residual power from the system, and may correct many problems.
  3. Connect the AC adapter to a wall outlet and plug the other end into the computer.
  4. Press the Power button .
  5. Is the Power indicator light (LED) on or off?
****If notebook power indicator light (LED) is on, the AC adapter is working correctly***
If the power indicator LED is off, the AC power adapter may need to be replaced. To determine if the AC power adapter needs to be replaced follow the steps below:
  1. Ensure that the AC adapter is plugged directly into a known working wall outlet.
    NOTE: To check the wall outlet, plug in a different known working device like a light, radio etc.
  2. Check all of the following connections:
    • The connection from the AC adapter to the wall outlet.
    • The connection into the power adapter from the wall outlet.
    • The connection from the AC adapter to the notebook.
  3. Press the power button again to test the notebook PC.
  4. If the power indicator does not turn on, remove the AC power adapter from the notebook PC and re-insert the battery. Then press the power button. If the power indicator light still does not turn on, then the AC Adapter needs to be replaced.
*****Reseating the RAM may resolve this issue.****
Step 1 - Remove the battery
  1. Slide and hold the battery release latch to the unlock position.
  2. Use your finger to lift the battery up and out.
Step 2 - Remove the memory module
  1. Locate the memory module cover on the bottom of the notebook.
  2. Remove the screw that covers the memory module.
  3. Use your finger or a flat head screw driver to lift the inside edge of the memory module and remove it.
  4. Push both tabs outward simultaneously to release the memory module.
  5. Grasp the memory module by the edges and pull gently to remove it.
  6. After removing one module, replace the memory expansion cover and then replace the screw.
Step 3 - Replace the battery
  1. Insert the battery into the notebook.
  2. Push the battery into the base enclosure until you hear a click.
  3. Connect the AC adapter and turn on the notebook.
fter the memory is reseated, connect the AC adapter and turn on the notebook. If the notebook boots normally and the Windows desktop appears no further action is needed. If this problem re-occurs often, contact an HP Support Specialist to schedule a repair.

Computer making noise

Monitor clicks, pops, or makes other noises. Issue: Monitor clicks, pops, or makes other noises.
Cause: This issue could be caused by any of the below possibilities:
  1. Monitor degaussing.
  2. Monitor changing resolution.
  3. Monitor syncing with the video card.
  4. Monitor warming up.
Solution: Noise when turned on or off It is normal for standard computer CRT monitors to make a click, pop, crackle, hum, buzz, or other type of noises when they are first turned on or turned off.
Noise when monitor goes into standby mode When the monitor enters a "standby mode" or "power savings mode" this is similar to the monitor being turned off. It is completely normal for the monitor to make a noise when the monitor enters this mode.
Noise when opening Microsoft Windows or other operating system or when opening a game When a computer opens its operating system, for example, a computer opening Microsoft Windows or when a user runs a computer game it is very common that the monitor will need to switch its resolution of the operating system or game. When switching resolutions it is normal for the computer monitor to make some type of noise and/or for the computer monitor to flick or flash.
Noise during normal operation If the computer monitor click, pops, or flashes while it is being used this is not normal operation. It is very likely that the monitor may be failing or a component within the monitor has already failed and could also potentially be a fire hazard. We highly recommend that the monitor be repaired, replaced, and/or looked at by a qualified technician.
