15 R2, battery and HDD cable issues
2 part question maybe I should ask this in 2 separates posts whatever. I have tried to refurbish an Alienware 15 R2 laptop and have troubleshot my way through to having 2 issues I haven't solved yet.
First off I brought a replacement battery off eBay and installed it, it was on 40ish percent out of the box and slowly went down and I cannot get it to charge I have drained it to 0 completely and it will not go up and laptop is only working while plugged in. Bios has nowhere to enable/disable but it says its there and working diagnostics say its there windows 10 says its there and "charging" on the task bar. I have tried 2 different chargers on it which I will admit are not oem I am keen not to waste money on one espec if this laptop isn't going to work. Have I just got a bunk battery or what I have no idea what to try next?
The second question is the internal HDD, I have the OS running off of an SSD m.2 drive and thats all good but I brought a HDD cable to go from the motherboard to the sata port on the drive I got it off ebay and it was meant to be for dells. Whenever the cable is connected to the motherboard it will not power on. Nothing to do with HDDs I've tried several different ones. I have tried 2 different cables (first one was too short to reach so brought longer only to realise neither work dumb ik) only thing I read was to try an 'oem' one for alienware as mine are just for dell.
Any advice much appreciated thanks.

For the first issue, does the system correctly sense the AC adapter, or does it show unknown? F2 at powerup to check.
For the second, is the part the correct one for your system? If the system won't power up at all, it sounds like there's a short somewhere.

@ejn63 It says "90W" next to AC adapter in the bios so I assume its sensing it.
Yeah I think it must be shorting it under the ebay page I got it from it said it was for dells? So I assumed it would work unless its a motherboard issue? Thanks

If the adapter is sensed correctly but the battery won't charge, most often the battery is faulty.
As for the SATA cable, I can't say much -- "compatible with Dells" doesn't mean anything, since there are many different cables, most often system-specific, for connecting SATA drives to notebook mainboard. Check with the seller.
If they insist it should work, have the cable replaced.
