I experienced the same thing with my laptop today and I removed the battery and plugged it in the wall and it started booting up. So it seems like if something is not functioning properly the computer does this until . So for mine its time for a new battery, for right now I will just use it plugged in until new battery arrives.

I am having similar problems but the blinking does not match the error codes.......The power LED is on and the wireless key is on, the Caps Lock is flashing steadily. A one second flash every 2-3 seconds. It looks like it will flash indefinitely without any repeating pattern.

I tried the solution involving blowing into the fan ports. I certainly did not believe it could be that simple, but the pc booted right up. Thanks for the quick fix!

Your solution worked great!

Same problem here. Got the laptop to boot up by blowdrying (on high)  through the air vent for a couple of minutes, then hit the power button and it started http://h30434.www3.hp.com/t5/Notebook-Hardware/Blinking-caps-and-num-lock-lights/m-p/1304077/highlig.... But it´s only a temporary solution...

I have read through this entire forum. i blew out the fans, no luck. followed directions on blink codes....

three blinks indicating memory issue.

i reseated the memory, no luck.

purchased new memory, not luck.

tried puting the old memory back in, no luck.

tried blowing out the memory seats incase there was dust in it, still nothing. 

i can acess bios so i have done every test possible, bios says the ram is there and test say that the ram is fine.

any help would be appreciated.

It seems like a differnt problem from mine... I couldn´t acess bios or anything. Caps lock led light was blinking nonstop, so I had no idea what the problem was.

Have you already tried hard reset?
