9570 2nd hd install 56whr battery help

Hi all so i have had nothing but trouble with this laptop since i bought it new. i am currently having touchscreen issues out of the blue so before i send it in for service i wanted to make sure i could get this upgrade working.
i purchased the following 56whr battery dell , hdd caddy ,screws,ribbon cable and rubber cushions for hd, and finally Samsung 860evo 2.5 1tb. I installed everything and the battery charges but when i unplug the laptop from ac power i stays on for a few then shuts off and will not turn back on unless i plug in the ac power. As far as the 2nd ssd goes it is not showing up anywhere not even in the bios and i have the drive enabled in the bios. I would like to know if anyone has successfully done this or can help me .

 

Unfortunately, issues with replacement batteries are often reported. Did you get if from Dell? Dell don't like to sell them (because they prefer selling extended warranties), and most "genuine Dell" replacements sold online are fakes where the most attention is spent for replicating the Dell sticker ;(

Have you tested the battery without the SSD, or with a 2.5" HDD? And look up how much current the SSD is supposed to draw. Bad batteries are likely to go off under load (I understand the battery protection circuit senses the voltage drop and shuts it off to prevent permanent battery damage). My original 56Wh battery still mostly manages to feed the laptop (512GB Samsung 950pro, 1TB HDD, UHD) but not at lower charge levels - if drained I have to charge it firstly, otherwise it fails to boot.

Edit: that SSD is rated 4W max which is comparable to 1TB HDDs and should be manageable for a healthy battery. I've seen mine feed max CPU load in early days, must've been close to 100W. Though on battery, the laptop is generally supposed to be downthrottled heavily by the power profile (but this throttling is not a straightforward thing). Check if it happens not to be so in your case, watch power consumption using HWinfo64.

 

Recently one can also test a m.2 NVMe SSD in an external enclosure (for a long while, only SATA enclosures were available)

Since you are changing 2 things at the same time (battery and ssd), it is difficult to tell whether you have a problem with the battery, with the ssd, or with both.

Thus, I'd try to isolate the problem by just changing and checking 1 component at a time. I'd first try having just the original drive in the computer and putting the new battery in the computer so that you can check the battery and either determine that there is a problem with the battery or that the battery is okay. If the battery checks out to be okay, that points you toward a problem with the ssd.

Have you checked to see what the BIOS is saying about the battery? If not, repeatedly press the F2 key immediately after starting the laptop by pressing the power button. When you get into the BIOS, check to see what it says about the battery. If your battery is not, in fact, a genuine Dell battery, the BIOS is likely to say that it is not a genuine Dell battery. Or it might say that the battery is faulty. In either case, that could cause the battery not to charge or it could cause the computer to operate only on AC and not on battery power. On the other hand, if everything checks out okay with the new battery, that would, again, point you toward a problem with the new SSD.
