Precision 7530 & Precision 7730 owner's thread

Replacing a fan, providing nothing else is warped should not be difficult, I would repair it if you are happy with it otherwise. It would also give you the opportunity to replace the heatsink paste with something that performs better like thermal grizzly, CM Nano, PK-3, etc. It also depends on how much time investment you have spent software-wise. Having to wait, retest, and reinstall/setup a new laptop might be more of productivity loss than the repair.

However, I'm usually equal to or more competent than anyone they are going to send over, and I would probably take over and do the pasting myself rather than let them.

 

Thanks for the replies folks.
Right now Dell says that the 18,000mAh is 180W and should work, but it will throttle things down, which is potentially OK.

My 7730 config would have:
1920x1080 screen non-touch
Quadro P3200 Graphics
two SSDs (512GB boot and 1TB data)
i9-8950HK
32GB non-ECC ram
97Wh battery

Has anyone else used a third-party power bank to power their 7730 once the internal battery is used up?
The sales guy says 15 hours battery life, but that's likely with the lowest of configurations (least memory, on-board graphics, lowest capable processor, etc.).

I'd like to get a solid 5 hours out of the on-board battery doing reasonable things and then be able to plug an external battery into it either via the power connector or the USB-C ports.

Thanks -

I read through this and did not find the answer. Does the Dell 7530 Touch option include a gorilla glass layer that increases weight and has glare?

Some of the Latitudes have on-cell touch, that has a matte finished touch screen without an extra glass layer and maintains the anti glare screen.

If someone has an easy picture of a device with a touchscreen, I would really like to see it if you are willing to share it.

 

A few points to consider:
(1) What is the capacity of the battery in Whrs? A big number of mAh is meaningless without knowing the voltage. However, I doubt if the capacity exceeds 100 Whr limit for lithium batteries which can be taken on a plane.
(2) If the battery can delivery 180W (which I doubt) then if you run it at full output then the maximum run time will be (100/180) x 60 minutes = 33 minutes (actually less as there will be conversion losses and the battery won't drain to 0% so maybe 20 to 25 minutes at 180W
(3) However, reviews such as this suggest that the maximum output is 65W, maybe 90W which will throttle the computer but last longer (and if the computer throttles itself to run at lower speed then it will be more efficient in terms of output per Whr). What's your definition of doing reasonable things? If you aren't using the dGPU then the peak power will be much lower.

The power companion has 65 Wh. If the maximum output is 65 or 90 watts then the throttling is going to be ridiculous. These machines don't play well with low-powered adapters. They typically lock at something like 0.8 GHz.

Is the 15 hours supposed to be with the power companion by itself or with both batteries combined? There is no way that this machine will run for 15 hours on 65 Wh (4.3 watts average? You'll be lucky to get it to run below 15)

 

Thanks for the advice! I called Dell and they were happy to provide a new whole system replacement. After looking at the service manual, it does seem to indicate that the fans and the heat sinks come out as a single unit.

 

Yes, it's very frustrating working with the Dell sales people as half the time I find I know more about their products than they do. No idea about the 15 hours, but like I said it's likely with the least power hungry build in the most energy efficient mode.

Right now with my M6700 I get about 4-5 hours with the battery slice attached for what I typically do. Some light CAD work, some light photoshop, big Word & PowerPoint documents, email via WiFi and a bluetooth mouse, etc. and it would be great to at least get that with the internal battery and then bonus time with an external power bank.

Dell is getting back to me on the external power options - the sales guy said he can't believe they don't have some solution for an external battery like I have with my M6700 . . . could be they don't have a solution and Dell just doesn't care.

Thanks -

You should be able to get 5-6 hours with the 6-cell battery if you have graphics switching turned on, the screen brightness pretty low, and you don't push the system very hard. I'm not aware of an external battery from Dell that works with this system, in fact I'm rather sure there hasn't been an option for this since the Precision 7000 series launched.

 

I just took a look:
"Caddy"

Bay with the caddy, not heatsink


From the looks of it, the caddy is only needed if you intend to mount the heatsink. @cp42 , If you use a relatively low power M.2 drive, you might get away with not using the caddy at all.
EDIT: no, scratch that. Its mounting hole is on the caddy. Still, a bit of cad work and a 3d printer should fix that if you can't order the part.

 

I´m a bit confused... i ordered a 7730 (will be delivered today) with the smallest nvme ssd and also have ordered a samsung 970 pro for more storage (original ssd remains). do i need an additional caddy to install the second ssd or is this only needed when upgrade sata-ssd to pcie-ssd?
