Was that a CD/DVD type that no longer works?...or, can you try and connect a bootable USB device to the laptop. Can you even enter the BIOS. If not, you're probably going to need to take the thing apart and look for loose or cracked parts. It's not that unusual for a shock to the motherboard to cause some chip to partially detach either. If you're not comfortable with taking it apart and can't part with it, your repair shop is probably the only option.
Hi sorry for the long story but it might help for diagnosing
I have had an acer laptop for awhile now (two years).
Recently the hard drive failed and I lost everything. The local computer repair place fixed it up by replacing the HDD. It seemed to work well again, aside from losing everything.
All was going good until bam, my phone fell on it directly where the hard drive is located. The hard drive seemed ok, apart from (maybe) some strange sounds, but I'm not sure.
I ran many disk checking software and all the results seemed positive but I wasn't convinced so I took the hard drive out of the computer and made sure it was connected properly. When I plugged it back in, and powered it up the computer screen wouldn't turn on. Only the power light turns on in the front, the hard drive light comes on when I boot it but turns off right after. The fan and HDD both appear to be working from what I can hear, no strange clicking or grinding.
I tried plugging it in to an external monitor to see if the screen was the problem but it's not that, to my knowledge.
Please help, I have been losing sleep over this whole process and I would prefer to not have to send it back to the repair shop if possible.
