Hello,
About 3 weeks ago my just over a year new laptop took a fall onto the carpet from 4 feet above... my screen was cracked so I ordered a new one and put it in yesterday. Now, I am having problems as the first original poster was having. I start up my laptop, the HP logo with a timer circle is spinning below it, then it says " 
your Pc ran into a problem and needs to restart", it restarts and then it says" Recovery- Your PC couldn't start properly. A required device isn't connected or can't be accessed. Error Code: 0xc0000185. With a bunch of other stuff written below it.. I have tried all the prompts possible. I did do a HP PC HARDWARE DIAGNOSTIC UEFI test, both the short and long one. It says FAILED Failure ID: GLXS3H-6MF76S-MFPWWJ-60S603 with the product ID: C5E40UA#ABA then right below that it says HARD DRIVE 1.
My lap top will not go into the windows screen now at all. I am guessing the fall my lap top took did some damage to the hard drive and that is the internal problem now. I did look at a video on how to take the hard drive out and I did unplug, remove batter, and take it out and took the controller board off, check to make sure nothing was lose or broken, and put back together and reinserted it into my laptop and I am still having the same loop as above come on.
INFO about my laptop:
-HP Pavilion G7-2247us Notebook 17.3"
-Windows 8
-750 GB Hard Drive
If you need any other information let me know and I will send it your way. I appreciate any help you give in advance.
Thank you,
