Compac disc boot failure

Our compaq computer went into sleep mode when I accidenty pressed a moon key on the keyboard. Then I pressed the power button, and ended up with a disc boot failure message. It says insert system disc and press enter, but I don't have a system disc for it. Hope you can help! thanks! Scott

    thank you teknowolf and leecom72.  i ended up hitting F10 repeatedly and getting into the system restore screen - but doing a hardware (i think it was) check first, which passed.  i then was trying to get into one of the options when it started the next time which involved "escape" (sorry, too tired to remember what that option gets you to), but when i repeatedly hit "escape", window booted up!

    i wanted to then check that the keyboard is set to restore from sleep mode, which it evidently IS (i guess i didn't just hit it again before when it went into sleep - i must have hit other keys first).  so, i'm not sure really how to prevent it from happening again, but hopefully this time just hitting the moon/sleep key again after it goes into that mode will bring it back.

    thank you again for your help!

First a word of advice to prevent this happening in the future. if you go into sleep by pushing the "Moon" key. Then you can wake up by pushing it again.

If you have a friend who has an HP or Compaq computer (With the same Operating system as you) then you can borrow their system disc to get you going.

When in sleep state the computer is running the startup routine (MBR or Master Boot Record) from the hard drive through the memory. So its fresh and ready to jump into action when you need it. The problem with this is that sudden and unexpected power loss. Can cause this information to get scrambled (Corrupted). Resulting in your situation. The only way to resolve this is by repairing the system with a system disc.

If you have access to a friends disc your ready to go. If not there's a couple of ways around this. You can contact the manufacturer and order one. Which will take time and probably shipping fees.

You can buy a retail copy of the OS. Which will save time but cost significantly more.

You can search torrent or other download sites for your restore disc and download and burn it (Be forewarned this is only LEGAL IF you have a valid liscense for the OS you are downloading)

Once you have your system disc, you can try a repair/restore. Procedures from here are slightly different depending on what Operating system you have. If you need help going further from here, let me know what operating system we're dealing with and I'll continue with the procedure.

This could be just the boot order, restart the pc and hit F1 or F2 keys, to get into the bios go to boot order and make sure the first boot device is HDD (hard disk drive) hit F10, save and reboot.

keep me informed

    ok, what i want you to do is, click on the "start menu" (round icon on bottom left hand side in vista) then you want "control panel" and then "power options". On the left hand side (i am assuming you use vista) select "change when the computer sleeps" click on the drop down menus and select "never" for all, then click "save changes" and ok, that will tell the computer never to go to sleep and your problem is solved!!!!

    take care and good luck

    Thanks for using Fixya

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.

How do I get my monitor back on if I accidently press the key in the top left corner (with the half-moon shape on it). What is that key for?

That's the sleep button
(half-moon -> night-time -> sleep).
It puts the PC into standby mode. Pressing the power button should bring it back to life.

I have a Compaq keyboard that has a half moon on the top left of it and I hit it and my monitor went blank. How do I get it back

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.

Pressed hibernation key and now the computer won't work

Unplug the computer for a minute and plug it back in. It should restart normally.

Usually you restart just by tapping a key in sleep or hitting the power in hibernate.

What is 1/4 moon symbol on top left of my compaq keyboard ? when i press it seems to put my computer into sleep mode . how do I get my computer started again ?

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.

Curious - What is the moon shaped key all about

this button puts the computer into sleep mode.


Sleep mode can go by many different names, including Stand By (Microsoft Windows 95-Server 2003), Sleep (Mac OS 8)-(Mac OS X) / (Windows Vista,Windows Server 2008), and Suspend (Linux). When placed in this Sleep mode, aside from the RAM which is required to restore the machine's state, the computer attempts to cut power to all unneeded parts of the machine. Because of the large power savings, most laptops automatically enter this mode when the computer is running on batteries and the lid is closed.
Though Sleep and Hibernate are generally thought as two separate functions, modern Macintoshes, Windows Vista (termed Hybrid Sleep), and some specially configured Linux machines also feature a variation of Sleep mode that incorporates the strengths of Hibernate. The RAM is copied to the hard drive before sleep mode is initiated, preserving the RAM contents in the event of a power loss.
ACPI is the current standard for power management, superseding APM and providing the backbone for sleep and hibernation on modern computers. Sleep mode corresponds to ACPI mode S3. When a non-ACPI device is plugged in, Windows will sometimes disable stand-by functionality for the whole operating system. Without ACPI functionality, as seen on older hardware, sleep mode is usually restricted to turning off the monitor and spinning down the hard drive.

Sleep mode

usually, to get a PC out of sleep mode, you either press the ESC key, press the power button a bit quickly, or press the sleep key agian. It really depends on the system. Try any of those to see if it helps.
