Re: Keyboard crescent key

The crescent key is called a sleep key. The Sleep key is used to put the computer into ACPI state G1 Sleeping from ACPI state G0 Working. The Advanced Configuration and Power Interface (ACPI) specification is an open industry standard first released in December 1996 developed by HP, Intel, Microsoft, Phoenix and Toshiba that defines common interfaces for hardware recognition, motherboard and device configuration and power management. According to its specification[1], "ACPI is the key element in Operating System-directed configuration and Power Management (OSPM)". try to find out about g1 nd g0 hope this helped

Re: Keyboard crescent key

That's the Sleep button, and you may not have it configured to do anything. If you'd like to change that, go into Start\Settings\Control Panel\Power Options and click on the Advanced Tab. From there you can select several options for the Sleep button.

Use of crescent key above escape key in model HP 5187-7583 Silver Multimedia Keyboard With Media Player

The crescent key is for the computer to go night night!
Look under power settings in control panel this could be a key that can be reprogrammed. Usually out of the box it will but the computer into sleep mode.

For some key boarda the "Fn" key and crescent both need to be depressed.

Shaking the mouse or hitting space bar will wake up the computer.

Hope this helps?

I am trying to find out what the blue symbols on the function keys of my sk 9020 keyboard stand for

The blue keys serve as a secondary function for your volume control, monitor controls and pause play fast forward rewind (in media mode). In order to use the blue keys that are numbered from F1 to F12, you must depress and hold the Fn key that is located at the bottom left side of the keyboard. Here is a way to test it: Open up any file that plays sound for longer than 1 minute (60 seconds). While this file is playing, hold down the Fn key and simultaneously press F8 and listen to the volume get louder or Fn and F7 together and listen to the sound get lower. The picture of the crescent moon F1 will adjust the brightness of your screen. F2 will magnify your screen. F3 will take you to your email. F4 will take you to your internet home page. F6 will mute the volume. F7 will lower the volume. F8 will raise the volume. F9 will rewind your video playing. F10 will stop the video. F11 will pause or play the video. F12 will fast forward the video.

I can`t get any upper case functions to work on hp 2011 keyboard what key do i press

1.Make sure the "Caps Lock" key is not on. Though this will be obvious to most people, if your keyboard is typing in only upper-case letters it can't hurt to check. Look at the "Caps Lock" indicator light on the top right corner of your HP keyboard. If the light is on, strike the "Caps Lock" key on the left side of your keyboard. This will turn the "Caps Lock" off, allowing you to type in lower case letters again.

2.Make sure the "SHIFT" keys on your HP keyboard are not stuck. Dust and dirt can build up on a keyboard over time, which can cause certain keys to stick. If either of your keyboard's "SHIFT" keys get stuck, your computer will type in only capital letters. Use a toothpick or cotton swab to remove the gunk from the key, which should help it return to its normal position.

3.Unplug your HP keyboard and then plug it back it. This will remove the device from your operating system and then automatically add it back in. This can have the same effect, essentially, as restarting your computer. If your keyboard was typing in capital letters due to an error being stored in your operating system's memory, that error will now be cleared and the HP keyboard will function as normal again.

4.Update your HP keyboard driver. Click "Start" and then right click on "Computer." Click "Properties" and then "Device Manager." Right click on the listing for your keyboard and then click "Update Driver." This will update the computer software that is associated with your HP keyboard. If your keyboard was typing in all capital letters as a result of an error with this driver, the error will now be fixed and you can use your keyboard normally again

I am using a multimedia office keyboard and I can't use the f keys such as F8 because they're other functions written on them such as "save". I can't find a second function key anywhere.

My version of this keyboard has a button in the upper left that toggles the function keys between their normal use and the MS Office specific use.

Crescent light on

Usually it means "go to sleep" (the crescent is intended to be a moon and mean "night"). It won't work unless you have the appropriate energy saving profile activated in the system, though (Control Panel -> Energy Saving)
