New Latitude 5470

So have put in the 11.4V/47Whr battery, and so far so good on the shutdowns.

I'd forgotten how absurdly much better the ergonomics on this machine are than the XPS 15/M55x0. The keyboard and mouse aren't super, but unlike the short stroke one and clickpad on the XPS, they aren't actually bad.

 

Gosh, you did the same thing I did to get my E5450 to stop randomly shutting down. New battery, and all was fine (well, it had one more residual shutdown from the laptop screws coming loose over the years - flex would cause a shutdown).

The slightly thicker chassis of the E5000 line allow for a much better KB then these paper thin KBs in newer ultrabooks, IMO. Some of them are so thin, there is less and less practical difference between them and a touchscreen KB.

EDIT: oh, I forgot we had a short conversation in the 5491/5591 thread, lol. I'm glad to see the new battery seems to be working.

 

Hey guys, odd question. Got two E5470 in the office. They've both have the quad i5-6440HQ processor.
It's pretty toasty a processor, for a think and light laptop. The CPU can reach 92-94 degrees c sometimes. It's still under the warranty. Should I get it serviced? Or is E5470 just known to be hot with quad?

(Can turn off turboboost - obviously it will get more manageable - though I imagine that loses some performance; if it were easier to repaste, I'd have repasted myself; however, looking at the service manuel, it seems I'd probably spend 2-4 hours repasting - too many steps; luckily since it's under the warranty, it's probably sensible to send them in)

 

The cooling system isn't super in these; mine is a bit toasty -- mine is seeing 89-93C after a major service (albeit with the slightly faster i7-6820HQ.)

My work is ordering me a new machine -- not clear if they'll be able to get a E5491 or just a 5480 -- as our security policy is changing away from allowing personal gear. Will be curious if the temperature improves any with the newer models.

 

Okay wow - you have a nicely loaded version, thanks for the reply.

That sets the expectation a bit I think - very helpful. I think Dell uses pretty standard thermal paste (sometimes those poor stick on things) / sometimes they brings a new cooling fan part - but if it goes to high 80s-93 degrees c after servicing, maybe it doesn't make much sense to service / probably I'll block out a weekend and order some Gelid thermal compound.

 

Hi guys,
Just curious. Is the same physical keyboard on the E5470 shared between E5450 5480, 7450 7470 7480, etc? (I know there are different versions, e.g. layout, backlit or non-lit, and single/dual click - but otherwise?)

 

Has anyone tried the new Toshiba RC100 SSD's for the WWAN slot yet? Would they work, since they are M.2 PCIE NVME instead of M.2 SATA?

 

Missed this before. The keyboard was not interchangeable with the E5450 when I had a key fail on mine; I tried borrowing one from an E5450 we had around the office. Single/dual pointing may also play a role (mine was dual, don't remember for the E5450)

Given how marginal power delivery is on the E5470, I'd be worried about the increased power draw, especially if you have the 4-cell battery rather than the 3-cell. I'm also not sure how the heat dissipation from there would be (is the clearance right to put a pad between it and the bottom case?)

That said, the real question is there a proper PCI-E connection there or just USB (for WWAN) + SATA (because we know it works, at least on the H-processor models.) About the only way to be sure is to try it. Would certainly be interesting.

 

I hope my i5-6440HQ would compensate for the power draw vs. an i7. It is mainly the PCIE I'm worried about, would putting in my NVME from the main slot at an angle work to test it?

 

I wouldn't expect trying the main-slot PCI-E in at an angle to get a good enough connection to work; trying to jerry-rig the right angle on the main one without the formal Dell bracket didn't work for me. That said, it's unlikely to do any damage, either, so while there's technically some risk in trying you're probably safe.

IME, the power draw difference between the i5 and i7 isn't actually that large, and once the battery in my system became marginal (at about the 1 year mark) it really didn't take a lot of load to cause a spontaneous shutdown. Going to the 3-cell fixed it, at least for now; I'd expect the health of your battery will make a bigger difference,
