HP Elitebook 840 G6 SSD in WWAN Slot

Boy, that was quick.

I meant if it was the Elitebook 1030 or 1040, but I can see that your Product #1G7F5AV is a 1030. HP stopped supporting SATA cards in the WWAN slot with the G3 laptops. I'm actually quite handy, but this is for work and I have to follow a different route there. I can't really do "my thing". Plus I wanted the three year warranty that I'm getting (no charge) to include the second storage. Phenomenal manuals 😁

So LiteOn, thank you. I was asking because most success cases were with the old SN520 by western digital. Interesting that you got good performance. Everyone else reports that the pcie x1 slot gives them about half a SATA drive's speed (200-250MB/sec).

Thanks for sharing!

I've installed 512Gb nvme pcie3.0x2 in my g5. It was detected by bios and works in windows. Speed is much slower then the system ssd has. But the real problem is battery consuming. It is discharging battery very fast even when the computer is totally turned off. In turned off system this ssd is warm and in one night battery discharged by half. That's the question.

Well, unfortunately modern laptops keep various subsystems powered-on even when completely shutdown. This is why there is a normal battery drain of 1-2% overnight. For some strange reason, this unsupported config you've created, and the (not-fully compatible) BIOS of your laptop, has the side-effect you've described. Not much you can do. I'd certainly DISABLE windows fast startup, and the dreaded modern standby (if you're using it), but I doubt it will solve these firmware-level issues........

About the speed, it's to be expected (normal). WWAN slots on HP laptops only have one PCIe lane. That's what I have even on my G8 & G9 systems.

Yes, I can confirm I’m having the same issue of battery drain unfortunately…

I have 2 HP EliteBooks x360 1030 G8, one with the second drive installed and the other one not, and the one with the drive installed, even after disabling fast startup in the BIOS and other related settings, and disabling fast startup on Windows 11, or even powering it off from Linux (Ubuntu) leads to the same battery drain… I’m thinking about removing it…

Not sure if HP could do something about it or even why the issue is happening… if the laptop should, in theory, be completely powered off.

(Not even holding down the power button for 10+ seconds when shutting it down… which I believe means hardware “issue”)
