Hello, i have an HP G62, i have the black screen at startup, no post can the get into bios, when i start it i hear the fans and hdd spin, but nothing but a red wifi indicator and continuous caps lock flash, doesn't stop and blinks every 3-4 seconds, i have tried taking out hdd and putting it back, tried heating it up inside a towel as suggested tried using one ram module, tried switching ram spots, tried unplugged wireless card ans starting without ram, still same thing, tried using just power cord and tried power cycling by taking battery out and holding power for 30 seconds, any help would be great tried everything i've found and no luck. Thanks a lot
 
In my experience that flashing light is usually associated with a bad motherboard. It sounds like you've tried the basic troubleshooting steps to rule out other issues. Further steps would require other parts to test with (different RAM, possibly even CPU) but I'd guess it's the board.

If you are happy with that older notebook, or simply can't afford to upgrade (and are comfortable attempting such a repair), look under the RAM slots for the HP motherboard model number ("replace with hp spare XXXXXX-XXX) where that number in X's is what you can look for on ebay.

LIsten ..if anyone says your motherboard is dead or bad motherboard so the person is truly an idiot without knowledge the simple solution is change the CMOS battery (find and buy original one) its cheaper actually, download BIOS update from HP official web by identifying your laptop, (link blow)
https://support.hp.com/us-en/drivers/laptops
run this file to a different computer and install into a blank USB (during installation the following software will ask for the USB)
After, insert USB into to your HP G42 notebook, press and hold windows key and letter B key together and the press and hold the power key for 3 seconds and release but keep holding WINDOWS Key + B, your Notebook will start and follow the instruction on the screen to update your bios.
Note in some HP models Letter V key works instead of Letter B key.
Thats it.

It ended up being a bad connection from the Screen and motherboard, i had to heat it up in a towel for sometimes an hour + to get it to recconect, took a few tries but try this if you need a solution.

Did you remove battery when heating up? How did you heat it up?

Hi,
I have got a HP G62 laptop from a client and the problem was the same as You described.
- Not turning on
- Wifi and Power LED was flashing

I did try out the hard reset and the other suggested solutions, but nothing helped me out.
I thought the problem is that the laptop overheats, so I removed the black plastic layer under the VGA cable. The intresting part was when the laptop was disassembled, but the necessery parts were plugged together, I wanted to test if it is working and it DID!

After some tries it turned out the source of the disbehave was a screw, which was holding the DVD drive.
So I changed it to a smaller one and it fixed it!
I guess the screw causes a circuit, but it is just a guess.

I hope it helps You guys out! ;)

Can you give a little bit more, I have g62, dissassembled on my desk at the moment, normally i just heat it up and it works after. but if you have a solution i'm all ears. I have all the screws and the dvd drive removed from the laptop and the keyboard and power switch just plugged in and still no load.
