Dell Precision 7670 Overview and Look Inside!

[@MsNIKITA]

You don't need an rubber strapy thing for those rounded dell power supplies. The laptop's power cord simpily wraps around the unit and fastens to itself using the little clip thing at the end. Pretty nice I think. Less things to lose or break.

A plastic pry tool worked for me without leaving any marks on the chassis. It was very tight but I removed all the "captive" screws in case they were still holding it together.

[@TheBrokenTech]

Yeah... I probably should have tried a plastic one. It's still mind boggling that's their design methodology.

[@RaleighLittles]

Can you show the case removal more closely? My case isn't coming off easily and I'm scared of snapping it.

[@TheBrokenTech]

You have to pry on it pretty aggressively. It's a terrible design.

[@ovDarkness]

Are 7000 series Precision worth it? If you are in a field where you are able to really use their features: certainly yes! Will I get another one? Well, if they will accept 192GB RAM, like Thinkpad P16 Gen2 I probably will. 128GB seems a little bit too small lately. Datasets are getting larger and larger.

[@aurick861]

Thank you for this. On the case thing: if you just need access to the internals the HP 840 g1, g2 those didn't even have screws, was just a slide lock. i need to choose between a Dell Precision 7670 and a Dell Precision 5570. Which one would you recommend?

[@TheBrokenTech]

It appears the 7670 comes with a much larger battery and the 5570 has no USB A ports. For me, that would put the 7670 out in front by a lot. Is it worth the extra 500 bucks, or more, would be the next question. For an enterprise user it's very easy to justify that. If I were buying one for at home or for a small business, I'm not sure that I could.

[@antiunclematter9502]

Other chargers are definitely compatible, even lower wattage chargers will work but they probably won't last very long before something pops. You might be able to get away with a slightly lower wattage if the laptop is off. I wouldn't do it with the laptop on though.

[@TheBrokenTech]

If I recall correctly, Dell changed the barrel size. So, the decade worth of Dell charges I have collected won't even plug into their newer models.

[@antiunclematter9502]

Hm, weird. I have several dell laptops, the oldest one being a latitutde 5480 and every charger I have is basically identical except for the size of the block and the wattage difference. I plugged the wrong charger into my 7670 (the 5480 one, which is like half the wattage), and it worked, only I forgot to unplug it and then was using the laptop later on and I heard the charger make a pretty loud popping noise, and when I grabbed it it was almost hot enough to burn my hand lol. It still works for the 5480 though, strangely enough. @@TheBrokenTech

[@TheBrokenTech]

I went digging deeper and it looks like you're right. It appears that my older Dell chargers are the same size barrel and will charge while it's off (I think... I'll know in a few hours), but it refuses to accept any power while is on. I suppose that's better than nothing. 😅 edit: It will charge while off from any of my Dell adapters, but will only charge while on from 90w and up, and only if it's pretty much at idle. The real bummer is it doesn't notify me when the charging stops. 😔 Still, a feature I didn't know it was capable of. Thanks for the correction.

[@Juxtaposed1Nmotion]

What model year is this? Thanks for the tear down!

[@TheBrokenTech]

I think that one is a 2022.

[@nm33x]

for my dell 7670 fan is not working regularly its overheating how to solve this issue

[@TheBrokenTech]

I've normally found most fan issues come down to the fans themselves.

[@antiunclematter9502]

It's probably working fine, the i9 just runs hot as hell and in a laptop it will likely just get throttled into utter retardation

[@YouTubeGlobalAdminstrator]

5:01 You should use a plastic spudger tool. :|

[@TheBrokenTech]

I honestly don't think that would have worked, but I probably should have started there. 👍 That said... it sure would be better if Dell simply designed their machines without the need to "pry" (the word they use in the service manual) them open.

[@nicovandyk3856]

And this is the best case, much better than my previous Precision. So what if there is 6x screws; it is a workstation, not a toy. I prefer it because it makes the chassis more secure/stiff - fell better quality

[@TheBrokenTech]

...or they could have designed the chassis itself to be more secure without relying on 87 screws (along with snaps) and the bottom panel to hold it together. It's a serviceability nightmare and more akin to their bottom of the line models from years ago. I have E series notebooks from over a decade ago that are still going just fine today (the one I'm using right this second is 12 years old). It has a single screw bottom panel. Anyhow... It's good that you like your Dell. You don't have to try to convince me. 😆

[@g1981c]

i have an older version and i broke off a few pieces of magnesium chassis prying the cover off - thought they would fix this BS by now ... and it is especially infuriating because i also have an even older version still which didn't have any clips with the cover coming off effortlessly - so they made it worse and are refusing to go back to good design.

[@TheBrokenTech]

I genuinely don't understand it. They got this right over a decade ago and have been moving backwards since then. 🤣

[@nicovandyk3856]

Really do not need touchpad buttons; this is much, much, much better (Have the newer Dell 7680). Power button not a problem, but I would’ve also preferred separate volume buttons; but not too big of a problem. And I am using my old charger, so don’t agree with the charger not being compatible.

[@TheBrokenTech]

I'd say the buttons are matter of preference, but I absolutely detest not having touchpad buttons. I did get the chargers wrong, but not all the way wrong. Smaller chargers will only charge the machine when its off no matter the workload the machine is running under. I would have expected it to derate performance for available power.

[@FirstLast-hh9fl]

CAMM is a new memory standard. It's created by a Dell engineer but is going to be a new industry standard memory technology, fyi.

[@TheBrokenTech]

The "is going to be" part is the thing I don't like. 😉 Dell patented it, which means they're likely going to try to license it, which means other manufacturers aren't as likely to support it since they have to pay money to do so. There are also other downsides, like you only get a single CAMM socket, so you have to throw RAM away to upgrade. I understand there are upsides too, but competing manufacturers are less likely to as interested in them. Unfortunately for the moment, Dell is using what _amounts to_ proprietary memory that is insanely expensive. They are are charging $320 for a 16GB CAMM card and a downright impressive $1249 for a 64GB version. Want to max the socket out at 128gb? $2500.... Hell. No. 😆 Anyhow, if the aftermarket supports it and prices drop by just about a full decimal, then I won't have any trouble with CAMM.

[@antiunclematter9502]

That's not a USB-C port it's a Thunderbolt port.

10minute chalane k bad heat bahut karta hai

[@nicovandyk3856]

Dell has intentionally developed CAMM as an open standard and has now been adopted by JEDEC and industry

[@TheBrokenTech]

I'm not seeing that it has been very widely adopted. At a glance, CAMM sticks are still more than double the price of SODIMM.

[@MrDelgrigorov]

Ho Zbook 16 looks like another league compared to this.

[@TheBrokenTech]

I have an older ZBook 17 and it has like 25 screws in it to hold the back on. 🙄 It needs ONE. 😆

[@MrDelgrigorov]

Since few years ago ALL Zbook Furys has exactly 1 screw to remove the lid and the battery is click to remove/install, there are more than 2 NVME slots always and the ram is always 4 slots. Zbook family contains few models but the only true workstation model is Zbook Fury and you can't mistake the rest of the Zbooks for true mobile workstations.

This is not laptop just a heater crapiest laptop

[@TheBrokenTech]

I don't know how it compares to the rest of the market, but I wasn't impressed with how it was built...

[@falkovon9135]

no usb C charging port at this point is just dumb. I use my Thinkpad C charger for all my other stuff phone; tablet, headphones, powerbank...

[@TheBrokenTech]

As I understand it, USB C is not (or at least was not at the time) able to provide enough power for engineering class laptops such as this XPS. The Dell charger can deliver 180W and I believe USB C was capped at 100W while this machine was likely in development. It's now been discontinued so I don't know what the newer models may use. That said, I don't know that you can't _charge_ it over USB C. Some laptops allow that as long as its powered down. I understand that isn't exactly your point...
