Dell Latitude E5570

Yeah, I am planning to tweak the power option and hopefully find a way to set the fan speed at highest configuration (don't mind the sound). The thing is, I know nothing about Ubuntu, it is really intriguing to know that you can override your BIOS o.o

Ehrm, apparently heat is inevitable so I'm just gonna ask this, how does the heat accumulates? I think someone said due to the long copper pipe, some amount of heat is dissipated through the underside before the fan can push it out. Does that mean at least the keyboard area is still pretty cool? Also, does anyone know where is the laptop air intake such that I don't block it?

 

This is specific to the 5470, but on mine the bad spot is the bottom towards the left side (viewed from the top), near the fan -- presumably from the heat sink. The rest of the bottom gets warm, but not uncomfortably so. The keyboard doesn't get noticeably warm on mine.

 

The basic cooling system of the E5570 is good because it is built to handle the heat generated by a quad core CPU + GPU (quite a powerful one in the M3510) so without the GPU there's plenty of headroom if you don't have a dGPU.

The problem with the E5570 (and E5470 / M3510) is that the current fan rules require the CPU temperature to get well over 60C before the fan starts running and, until that happens, there's no airflow to cool the surfaces. Maybe Dell will appreciate the problem and introduce a lower fan speed starting at a lower temperature.

The air intake is the big grille on the bottom. To improve the airflow while on a desk I have put a couple of 4mm rubber bumpers on the bottom near the back corners.

It's much the same on the E5570 - the hottest part of the bottom is the back left corner near the fan and heatsink which happens to rest on the left thigh when used as a laptop and the heat is noticeable when wearing short trousers. Probably the warmest part of the keyboard (at least if the fan is not running) is the centre, but it is never uncomfortable. The palmrest / touchpad stays cool except possibly the bottom right corner over the SSD may warm up slightly under heavy disk access (but as the keyboard is offset to the left you don't normally have a palm resting on this area).

Overall, this is one of the better cooling systems I have come across with the extra benefit of doing the job quietly (at least in the non-dGPU configuration).

Not ideal though. As John mentoned, bios doesn't Iike fan running if CPU isn't at a high temp, so if I force it, fan goes (high, stutter to low when bios takes over, shifts back to high, repeat).there's probably a utility that is this on Windows too


I use my e5470 at home with an edock, which raises the back up. I try to keep the left side clear of any items, because it can become a hairdryer-like heater when CPU gets loaded

 

I've just added another 500GB of storage to my E5570 by putting a 2242 Transcend MTS400 into the WWAN slot. The computer had no trouble recognising it - I just checked in the BIOS that SATA 1 was enabled.

PS: I see that this internal SSD is showing up as a removable drive which isn't what I want. Any suggestions for the easiest way to tell the computer that the SSD is non-removable.

 

@z3n0mal4 How did you get your A-DATA SP600 in wwan working? I don't see it in Windows & Linux. My BIOS is is already in AHCI.

I tried to toggle between legacy and UEFI but it makes no difference. Is the SSD supported in a i5-6300u configuration?

Attached an picture of the slot. There are not that many PCB traces towards the slot

 

Have you got the card the right way up? The card has two notches and the slot has only one key. I recall having to make the decision when I put the Transcend 2242 SSD into the WWAN slot of my E5570. After brief deliberation I decided that, sensibly, the chips would be on the top side because, in some computers, the socket is close to the board and wouldn't have space for the chips to be on the bottom side of the SSD. That worked for me so I didn't try the SSD the other way up to know whether or not it fits.

Next, try reseating the SSD. Insert it into the slot at about a 30 degree angle (same method as with RAM) then push it down and fix with a screw.

Also make sure that the SATA 1 socket is enabled in the BIOS.

PS: Dell has posted a new BIOS. The main changes are for Thunderbolt issues. However, I installed it to see if they had improved the fan rules. My initial impression is no change: There is still no fan speed slower than 2200 rpm.

 

@psu_freak As @John Ratsey said, check the SATA-1 to be enabled in BIOS, under System Configuration - Drives.
That's the slot for the SSD, default is unticked because it's not used.


Regarding the buzzing, i noticed it is louder while the laptop is being charged, and i believe it to be iGPU related (meaning CPU). Correct me if i'm wrong please, but if i have a youtube browser and watch a video, the buzz is there. If i scroll down to the comments part and the video window is not on screen, then the buzz is more subtle.
Also, while on battery, the noise is hardly audible in a office enviroment

 

Thanks for the replies. The card only fits in one way. I already tried to reseat the SSD, but it doesn't make a difference.

SATA-1 was always checked at my laptop. The card works in the slot which is shared with the harddrive, but I need that slot for the harddrive.

Is there somebody who can make a picture of a WWAN slot on a non low power CPU? I currently don' t know anybody who is using a SSD in the WWAN slot with a low power processor.

In a post of the E5470 I see this list:
SATA-0 - ?
SATA-1 - WWAN
SATA-2 - SATA
SATA-3 - ?
M.2 PCIe SSD-0

My laptop doesn't have a SATA-3 in the list, I have a total of 4 check boxes. The people where it works, do they all have SATA-3 in the list and a total of 5 check boxes?

 

How do I set a timeout for keyboard backlit? It appears the backlit stays always on as long as the laptop is powered on. I would like it to turn off after e.g. 30 or 60 seconds of keyboard/touchpad inactivity.

Edit: OK, I've found the settings for keyboard backlit timeout in BIOS, but there had to be some bug, as it was set to 10 seconds on both AC adapter and battery. I had to switch them to different value and save settings and it works fine now.
