On My Dv5-1125nr both the caps lock and num lock keeps blinking when i turn it on. It's wont boot at all. What kind of hardware problem is this?


First remove the battery and power cord for about a minute. Then plug back in and see if that helps. Otherwise please read the following:

LEDs near Caps Lock and Number Lock keys blink when starting notebook The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up. If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition. Knowing the number of blinks is helpful when you contact an HP support agent for technical help.

If all the LEDs then try to turn off the power switch, wait a few seconds, and then turn it back on. If all the LEDs are still blinking, press Go and Job Cancel buttons together and let me know what LEDs stay on.

LED Indicators - LaCie 2big Network

  • Rear LEDs – blinks red/blue until corresponding disk is powered on, then turns solid blue.

3 flashing lights


the 3 blinking LEDs mean the lamp may be defective. Be sure the lamp is making contact with the sockets within the lamp compartment, also make sure the lamp is the correct one for your model. The set can be reset by unpluggimg the power cord for 5 minutes then plug it back in, if the 3 LEDs still blink check the lamp if its making contact and its the correct lamp for your model, suspect the ballast
