Try booting into Safe Mode then go into the Control Panel and change the Power Options.
Turn off the computer, then hit the power button to turn itback on and immediately start hitting the F8 key repeatedly until you see SAFEMODE. Take the Safe Mode option and let it boot up. Safe Mode will lookdifferent to you, the screen will be darker and the icons bigger, this isnormal.Once safe mode is up click Start/Control Panel and look for Power Options.
The moon icon usually indicates that your machine is in SLEEP mode. Try closing and opening the screen lid. If not, there might be a problem with your laptop waking up from sleep mode. Try holding the power button. This will turn it off. Turn it on again by pressing the power button once more. Hope this helps! Have a nice day.
If the shape of the symbol is the cresent moon....then that is the "Sleep" shortcut key. It will send the hard drive into standby mode. In a lot of systems, this sleep mode can really corrupt and damage system files. I always recommend disableing sleep mode in the power options section of the control panel.
Reboot the computer in Safe Mode by pressing F8 at boot up and selecting Safe Mode.
Then go to Start->Control Panel->Keyboard. Here you will find settings of this keyboard. Disable the sleep mode. And your monitor will come alive. Whenever you have any problem you must first use the control panel and try your hands at DIY. But do remember what you did in what sequence to undo it later if need be.
the half moon indicate an sleep mode when you open your laptop the sleep mode is already activated thats why it goes to shutdown reason is your sleep mode key is grounded try to consult it to your your dealer
The half moon usually means the computer is in SLEEP MODE. Normally, pressing the spacebar will wake the computer up but I have noticed that sometimes, the computer can get "stuck" in sleep mode. If that is the case, you can hold the power button down (until the power turns off and the moon disappears). Wait a few seconds then hit the power button again to turn the laptop back on.
You are correct. The moon is sleep mode. Closing and opening the lid will often take it out of sleep mode. You might have to "unlock" the keyboard as well by entering a password (just hit return if you haven't entered a password.)
Under power options, you can select what the computer does in sleep mode.
At first light it DOES sound a bit confusing.
First, the definition of the term 'NON-LUMINOUS'; 'Not capable of PRODUCING light but can be capable of REFLECTING light from another source'.
For instance, our MOON is NON-LUMINOUS as it REFLECTS light from the Sun. The SUN is LUMINOUS as it produces light that is REFLECTED off the surface of the moon. And so, LUMINOUS means capable of PRODUCING light.
Now closely examine your flashlight.
The BATTERIES produce electrical energy which is transferred to the BULB which emits light, thus LUMINOUS. The tiny little BULB emits quite a lot of light for its small size. However, the bulb is contained within a concave silvered cone which REFLECTS,(NON-LUMINOUS) gathers and channels the emitted light from the BULB (LUMINOUS) into a BEAM which ILLUMINATES whatever you are pointing the flashlight at.
Our cameras would be just paperweights if there were no NON-LUMINOUS surfaces for the light to REFLECT off of, back into the camera lens, onto the 'plate' thus etching the image. For example, take a photograph in the dark without the flash and what do you get. No LUMINOUS, no NON-LUMINOUS.
And so there we have LUMINOUS and NON-LUMINOUS, ILLUMINATING our lives. Enjoy! :)
