Re: Compaq EVO N1000C boots up to desktop, but the screen...
How do you know that it boots all the way when you cannot see anything on the screen?
To check if the video card on the laptop is functioning properly, connect the laptop to an external monitor. When you boot up you may see Windows start on the monitor, if not press the Fn key plus one of the Function keys that switches (toggles) between the LCD and the external video (usually one of the keys from F3 to F8).
If you don't get a video image then the video card which is part of the motherboard, is faulty - it can't be repaired cheaply, usually requires a new motherboard.
If you get a video image on the monitor, then the LCD could be faulty or the LCD video and/or backlight connectors on the motherboard is not making proper electrical connection. Then it may be fixed by reseating them.

If you just replaced the CMOS battery, when you took the battery out it lost all of its BIOS settings. You will need to go back into the BIOS and set the time and date as well as all of the other settings that you require. If you do not know all of the settings you can find the option to set it to the default settings. This will usually work to boot the computer.
Be sure to email me back if you have any more questions orif you need any assistance with this solution.
I'm not familiar with this laptop but all I have worked on in the past have a series of tabs along the top of the keyboard, usually I can use a jewellers screw driver to gently ease one tab back at a time and then slip in something like a credit card to keep the tab back.
Once you have all of the tabs held back you should be able to lift the keyboard out.
For the built-in wireless on this model (EVO N1000C) the key combination to enable/disable wireless is Fn + F2. If pressing the Fn and F2 keys together does not enable the wireless, it may be disabled in the BIOS.
If you need to check this, here are the instructions to enter the BIOS:
Turn off the computer. Power it on and immediately start tapping the F10 key about once per second until you see the BIOS screen.
hi, first check the keyboard is on (there is power on for the keyboard and mouse device in the newer type of laptops) and while the windows start before boot see the num light is blink and the power on will blink. if it will not blink. Goto the bios setup and here while you switch on the system press the DEL or F2 key. it will goes to the bios setup and see the keyboard is enable. if it will not work then you have check with the other usb or ps/2 keyboard connect it and try it . if prob comes again inform to fixya.com
Looks like the battery is screwed. This usually happens with laptop batteries when not recharged for a certain amount time(Usually around 2-3 months). Replace the battery and every thing will be back to normal.
