Hello, first thing to check is the memory Compaq cq 56 starts up fan runs but no screen - edcad6ab-5969-4cad-8769-8b40e3f44425.jpgSecond the most common would be video chip failure, we get these all the time for repair. Faulty motherboard design which make the chip overheat and come unsoldered off the board.

SOURCE: Compaq CQ50 laptop powers on, but does not boot.

I'd try messing with the memory. Try booting one single stick in each of the slots.

I've noticed that this happens pretty frequently with certain hp / compaq models.

If you've already tried that you can try removing the cmos battery for 5 minutes but aside from that the motherboard has probably gone out :(

I hope it's under warranty!

SOURCE: black screen on booting my Compaq 610 notebook

If it seems like you're accessing the hard drive (drive light comes on, flickers intermittently, then goes off, it's a good chance your screen is bad.

First thing to do is plug in an external monitor and start up the laptop. If it comes up with windows, you know it's the screen.

To find out if it's the backlight, or the lcd, toggle the monitor function and shine a flashlight on a slight angle to the screen. If you can faintly see what was displayed on the external monitor, then the backlight inverter is probably bad.

If the external monitor didn't come up, you're probably looking at a motherboard.

The good thing is that all of those are covered for one year under Compaq's warranty, on a new machine.

If you are able to use the external monitor, back up your data, because HP/Compaq usually reformat the harddrive. Additionally, if you've added memory, pull the cards. They want it sent back the way it came from the factory.

What key is scroll lock on presario compaq cq 56


Don't you have a key with a padlock icon?
That should be your scroll lock.
If the color is not white, you may have to press first a function key with the same color as the padlock icon.

My cq 81 pc startsup but black screen. totally blank


the caps lock key is flashing a diagnostic code. If it just flashed once then a pause and repeats this continuously then you have an early chipset initialization failure and the motherboard need to be repaired or replaced. If it's flashing some other code a quick google search for "hp diagnostic LED codes" will find the correct cause for the code.

Laptop white screen


Maybe the lcd screen is going bad. Try an external monitor. if the external monitor works fine then your lcd screen on the laptop is going bad. If the external monitor behaves the same way, then the Video Card on the computer is going bad.

Plug in an external monitor and see if thedisplay shows up on it. It can be any kind of monitor even the old big fat crtmonitors as long as it has a vga cable to connect to your computer's vgaport. If so that proves your video card is ok. The video will showon most systems when you reboot without you having to do anything. Some systemswill require you to hit the FN (Function key) + F1 thru F12. Hold downthe FN key then hit the correct key for displaying on the monitor (F1 thruF12). The correct key will normally have CRT/LCD on it or it will havethe icon of a display.

No wireless connection for laptop. Linksys router - model #wrt160n v2


you can run a direct line to that router and go to the cisco web site and get the information you need to run that router. its a pdf format and is 2.56 Meg. Try this

SecureEasySetup (Orange/White) The Cisco logo is the Router's SecureEasySetup button. It

lights up and will stay orange when the Router is powered on. The color orange indicates that

the Router is not using the SecureEasySetup feature, while the color white indicates that the

Router is using the SecureEasySetup feature. When the Router enters SecureEasySetup

mode, the Cisco logo will turn white and start flashing. After the Router has generated

the SSID and WPA Personal key, the Cisco logo will stop flashing and stay white.

To clear the SSID and WPA Personal key, press and hold down the Cisco logo for five seconds.

The Cisco logo will flash slowly as the Router resets itself. The Cisco logo will turn orange to

indicate a successful reset.NOTE: SecureEasySetup is a feature that makes

it easy to set up your wireless network. If you have SecureEasySetup devices, run the Router's

Setup Wizard CD-ROM and follow the onscreen instructions to use SecureEasySetup.

Power (Green) The Power LED lights up and will stay on while the Router is powered

on. When the Router goes through its selfdiagnostic mode during every boot-up, this

LED will flash. When the diagnostic is complete, the LED will be solidly lit.

DMZ (Green) The DMZ LED indicates when the DMZ function is being used. This LED will

remain lit as long as DMZ is enabled. WLAN (Green) The WLAN LED lights up when

the wireless feature is enabled. If the LED is flashing, the Router is actively sending or

receiving data over the network. 1, 2, 3, 4 (Green) These numbered LEDs, corresponding with the numbered ports on the Router's back panel, serve two purposes. If the LED is continuously lit, the Router is successfully connected to a device through that port. A flashing LED indicates network activity over that port.

Internet (Green) The Internet LED lights up when there is a connection made through the

Internet port. A flashing LED indicates network activity over the Internet port.

Good luck
