Scroll & Caps Lock blinking - DV4-1120 does not boot. :-(

[onthe_fairway]

hey joe_k,

just wondering if your tried booting without cpu.  I have same issue with single flashing caps/scroll light.

I did read in another forum it may have resulted from cpu being oc'ed....did you notice fan constantly on?

thanks for any advice!

same problem here. found this on Hp service portal:

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.

Caps Lock/Num Lock LED Component Tested Error Condition

LEDs blink 1 time CPU CPU not functional
LEDs blink 2 times BIOS BIOS corruption failure
LEDs blink 3 times Memory Module error not functional
LEDs blink 4 times Graphics Graphics controller not functional
LEDs blink 5 times System board General system board failure
LEDs blink 6 times BIOS BIOS authentication failure
Error code explanations
The sections below provide some common explanations for each error code listed in the table above.

I run a small laptop repair shop and ran across one of these dv4's, and thought i would tackle this project on. after a few hours of trial and error and research i found that the continuous blinking caps lock light problem came down to the video card.

what i did to find this was took the palm rest and keyboard off, and pressed where the video card is located at (which is near the hdmi port) and pressed the power button. wala video's up no problem.

looks like hp still cant get their solder problems in line. very dissapointed in hp, and would never buy on of their commercial products again.
