HP Compaq presario cq40 cannot turn on but all the lights are turning on plus blinking caps+num lock

HI 

so i got this laptop that does not boot and does not even turn the screen led on... the power lights are onn plus i noticed the caps lock and the num lock lights keep flashing at the same time every 3 or 4 sec... before this it was working fine i remember the last time i use it the screen turns black... because the battery was low... then when i went home and connect my charger... nothing seem to show up... the things that I tried is rreplacing the ram modules, unplug battery and the power adapter then just connect the power adapter without the battery but still nothing.. plus i already tried connecting to a external monitor, a projector and also a tv with hdmi cables, still nothing.. i tried spamming the f9 f10 f2 but nothing shows... I am seriously worried now because all my documents are in the laptop... any suggestions?

Your motherboard is dead based on your description of troubleshooting you have tried. To retrieve the data off the hard drive just remove the hard drive and attach it with a usb to SATA cable to another computer and then you can copy and paste files off the hard drive. 

Just search usb to SATA in ebay or amazon.com. 

See starting at about 3:10 in this video shows how to expose and remove the hard drive:

Sorry for the delay reply.... it's because I guess i already fixed it or maybe some wires are loose.. here's what i tried and my solution...(from my opinion) I tried disassembling all the components and found out that the little square thing or the processor was not placed well... I think it's because last time I tripped on the charging cable... Then I took the processor out... wiped all the grease then placed the processor back in... then I assemble everything back n then everything was doing fine... so... it's either the component cables or maybe the processor... but at the end everything was back to normal... hope this help's everyone and also thanks for replying.. your slution may help other people... Thanks 🙂
