Dell Precision 7540 and 7740 Owner's Thread

Am about to buy either a Precision 7740, or a Thinkpad P73 for work, but need to know the maximum opening angle of the Precision 7740's lid. I have a M6800 (which I love dearly), and the lid opens all the way until it's flat, which is great. I work with my laptop's screen positioned under my large external monitor, and so need the lid to open quite far. I'm worried though that the redesigned Precisions can no longer do this. Don't want to get a Thinkpad, but may have to.

7740's Lid can goes flat too.

 

Yes, the lid can open to a bit over 180° just like the M6800.

 

So it wasn't just my impression. For me the performance drop is in the 3-5% area, but still too much for a cpu that has been released just 6 month ago as the top for notebook. I hope that AMD ryzen will hit some workstation model (like precision) soon, so we can get rid of these ridiculous intel continuos put-a-patch awful work.

 

Phew, that's very good news. Thanks (to both of you)!

Just repasted with liquid metal (conductonaut) and I must say I am impressed - max temps dropped by 15+c when running Cinebench (doesnt even hit 80c now), but for some weird reason scores remain the same (1909 CB15, 4165 CB20)... so what gives? It still appears to hit PL1 of 100w and then PL2 of 75W, even though throttlestop has them set to 105w and 90w.
Not sure whats going on here, I've definitely seen to hit higher power limits before... Any ideas?
Edit: also have now seen frequencies of 4.5Ghz+ during load on all 8 cores, so I guess there was no hard limit of 4.4Ghz built in. On TSBench run and 64M score is now 4.3s vs 4.6s before, 256M score is 17.3s vs 19.something seconds before

 

I might have directed you to these posts before, but just in case you haven't seen them, it looks like setting the power limits in ThrottleStop can be finicky. (I haven't messed with the power limits yet myself so I have no first-hand experience.)

Thanks, that helped. Not sure why but setting powerlimits to 100w and 90w did not work, but setting 120w and 100w did... CB20 score hit 4300:

 

@Thread, can anyone with the regular fingerprint + NFC share the part number for the palmrest, dell screwed up on my order and shipped me a regular palmrest, now they don't know what the part number is for the palmrest with regular FP and NFC...
Help would be greatly appreciated.

 

This used to be important to me for the same reason. Not any more, but your question got me curious, so I tried it:

The laptop easily opens enough beyond 180 degrees that the lid will lie flat on your desk. As opposed to, if it would open at exactly at 180 then the edge will be about 2cm off the desk, which is probably not what you want. I haven't measured the angle, but you can open so that the lid rests against the desk and stays there in a relaxed state: it's doesn't try to spring back up, which tells me that it's not being pushed to its limit.

BUT... The power adapter connects to the back, and the plug/strain-relief pokes out far enough that the edge of the lid does not want to lie flat. It's about 2mm from flat (no ruler, I eyeballed it). A small amount of pressure makes it go flat, but it springs back up. For a one-time thing I'm not remotely concerned about the pressure needed. But if it's going to be that way all the time then it's constantly applying a torque to the power connector, which would bother me. A small torque, the fact that it would bother me probably says more about me than about the torque.

I don't know if you could fix that with a heat-gun to permanently adjust the shape of the strain relief. But there are right angle adapters: I started searching and google automatically completed my thought to "dell laptop right angle power adapter". So $7.50 will fix that if it's an issue for you.

If that's your only holdup on the 7740 then I'd still absolutely recommend it, and get an adapter after you try it out.

And the power plug is moot is you're going to use a thunderbolt docking station, since they power the laptop via the ports on the left side.
