Good Morning, I have a HP 15-DB0005DX and I am running out of space on the 128 gb Hard drive (L20381-001). I have a Samsung 850 EVO from my old laptop that I already cloned the HD to and would like to install it. I found the manual here and took it apart (I've taken many apart before) and there is a slot for it but I do not see anyway to connect it. I did not realize the OEM HD was a diff type. How/what do I do to upgrade this HD. Also when I put it back together it will only start when plugged in to AC. Nothing happens with just the battery. When I plug it in it says cmos sum is invalid, check the bios. Thanks, Mike

Hi Mike,
The battery seems not to be attached correctly to the notebook, or it is no longer working. That is why you are getting the error at boot. You can try reattaching the battery and see if it works. Look and see if there are any problems on the motherboard. On page 41 of service manual you can see how the battery is installed correctly.
You can add a 2.5" SSD or HDD, however you will need to purchase.
Hard drive bracket part number L20455-001
Hard drive connector board part number L20454-001
The parts might be difficult to find, however you can try an online search.
You could also just upgrade the M2 SSD to a much higher capacity M2 SSD. There is no limit to capacity.You could even use a faster M2 PCIe NVMe SSD which would also give a boost to performance.

Hope it helps,

Thanks, So I can install my EVO as a second hd to boot or switch back and forth from. When I opened her up I was confused, at first I saw the empty slot where I could install the EVO and thought I was loosing my mind because I thought there wasn't a hd installed, lol. How does the EVO compare to my oem hd (L20381-001). What kind of performance increase could I expect with a M2 PCIe NVMe SSD. I'm not a gamer or anything and trying to get the fastest is a never ending dream. I'm trying to decide what would make more sense money wise and performance wise. Any idea about the battery problem. I'm guessing when I removed the battery it changed something in the bios? Thanks, Mike

Sorry, I forgot to say, I have tried reinstalling the battery several times. I have come across this problem before on other laptops and reinstalling it fixed it, but I never got the cmos message before. Thanks, Mike

Well after researching some I updates my bios and now the ;laptop starts again on battery so all is good in that respect. I've researched the cable and bracket to install the Samsung EVO sshd. Now I just need to find out what would be best, install the EVO--buy a new bigger sshd to replace the OEM one or both. I need to find out what would benefit me most performance wise and weigh the cost both ways. By the way my AVG tuneup now says I'm at 93% which is way higher than it's been in a long time.
Thanks, Mike

I found the 2 parts
Hard drive bracket part number L20455-001
Hard drive connector board part number L20454-001
from Impact Computers. Now I need the cable that goes from the connector board to the motherboard. I thought it would have come with the connector board but it didn't. Where can I find the cable and what would the number for it be? Why does every time I take the ;laptop apart and remove the battery and put it back together again it will not start on the battery without downloading a new bios? When I try to start it on a/c it says checksum error and defaults to the original bios. Thanks again, Mike
