Thanks but I've read related posts and couldn't find anything on those "plug & play" cards and that I won't need to do DSDT override and use any other modification

Is it not enough for you?

@svabo
I've not tested unfortunately, just concluding which was written in this topic before. I'm recommending you to read related posts here to get all details before making any decision.

I can use mSATA SSD in it

You'll NEED to make a bios patch before msata will be usable because corresponding sata port is disabled by default. It will run at the SATAII speed, and it will not be bootable (and not possible to select as bootable on power on).

@svabo
1. Well,

is a straight plug-n-play implementation

I'm not sure about adapters, but mostly like they're not differ too much.

2. Patch BIOS, solder signal caps and use it's mSATA capabilities. To use any other usb device you'll also need to remove the whitelist.
Yes, it's only for modem.

3. HDD caddy is a plain passive adapter and a bunch of plactic, there is not much possibilities to worse the SATA connection.

That was interesting to test.

 

3720qm and a 3320m, both at 2.60 GHz nominal freqs.

Test bench:

Dell Latitude E6430, 2x8GB DDR3-1600

Linux Mint 20 at min. brightness

radio off

Battery off

 

Idle Watts shown on Kill-a-watt thingie:

3720qm - 7.0 W

3320m - 6.8 - 6.9 W

I would call that a 0.15 Watts difference, rather than 1.5-3.0 Watts. Hardly a factor to energy consumption.

Hmmm, that's strange. I've used BatteryInfoView to trace power consumption a year ago. All off, display off, power saver profile. The summarized minimal idle power consumption on mine 2570p with it's stock 3210m cpu has been around 5.5W, and under the same conditions but with 3740qm it didn't fall below 7.8W.

With light loads like code writing (nodejs, autocomplete, type check etc) or web browsing with 4 core cpu my laptop works around 4 hours, when with 2 core it can run 6. Two hours! So i've decided to switch to the 3210m back, since i need portability first.

Here the 7720qm already seems to be more efficient with around 0.9 W.

Well, it can be predicted - lower frequencies => lower Vcore.

Idle consumption of quad i7 should be comparable to dual core

Not really, two cores consume about 1.5~3 extra Watts when idle.

Can I improve the battery performance

Limit the max CPU perf % in Power Settings, it will limit the max frequency. AFAIK you can also set PLx power limits using Intel XTU, which will be better if you need good single core perf, but i've not tested it.

thank you in advance for detailed informations. I have red on the first page that a good CPU with a TDP of 35W and "cooler" temperature could be the 3632QM. From your info I understand that this CPU is a compromise between 3612QM and 3740QM. What do you think about?

3632 is faster than 3612 for 100MHz, so they're in the one grade. 3740QM have a +600MHz that will be a noticeable perf boost, but it also will heat like in hell at full load. For selection between 3612-3632 you can search for power efficiency comparisons, i've not digged in that much.

Hi to all, I have recovered an old HP 2570p with SSD and RAM upgrade. Now it's really quick with Win10. I woud like to know if a CPU upgrade it would be a good improvement. Thank you.

It based on your needs. If you're planning to use 2570p as a portable laptop, then you have 2 variants: take a most powerful 2/4 (e.g. 3540M) CPU or a most powersaving 4/8 (3612QM). Both of these choices will bring a noticeable performance improvement over base i3/i5 cpu. I suggest to take a 2/4 cpu since it will consume less power in the lightweight scenarios like web browsing or text stuff (but for multithreading apps 4/8 is a better choice). If you will use it at home and ready to make some cooling improvements, then you can give a look for 3740qm.
The graphics part (HD4000) is too slow and lacks support nowadays, and the cooling system of the 2570p not designed for 4/8 and heavy tasks. If you're good with the current performance, then it makes sense to just leave it as is.

Hi everyone,

how is the actual situation about WWAN cards? Are we still constrained by a whitelist? or has it been modded?

I would like to put a 4G card so that I could put a SIM on without ruining the battery of my phone.

Thanks in advance.

Windows 10. Never had any trouble with it.

 

It's just your subjective opinion. Some people likes to use ancient things like s**t of mammoth. 

If you're okay with laggy UWP interface, background activity, too heavy interface design for standard HD screen and general idea "OS needs to be smarter than user", then this OS is good for you.

better  compatible TN display

AFAIK there's none really different options, all available 2...3 displays comes with ugly "white" bluish LED backlight without any PWM compensation. And there is two possible solutions for each problem, both tricky:
1. disassemble the screen, extract backlight strip and resolder the LEDs to better ones - i'm can't even guess is those LEDs possible to find. However on aliexpress you can find some LED strips for generic laptop screens, or buy a broken IPS screen from thinkpad and try to use it's strip;
2. This issue needs to pach a video bios for a new PWM frequency - this was already done by the x2*0 users. Or try the IntelPWMControl. Or as theoretical alternative - PWM-to-Linear conversion module installation. Like this: https://www.aliexpress.com/item/4000269274889.html

Probably good, idk is this PRO line SSD or just EVO, but it's Samsung at least.

Same, but if you're using linux you may get a "happy" time with intel cards.

Intel Core i7 i7-3740QM

Too hot. 3612qm or top two-core i7 solution will be definitely better for everyday use. I'll recommend you to set max performance % to 99% in windows, that will cap cpu to 2.7ghz. And 4-core processors are hungry in idle too, if you will use nb for internet or scrolling - it will discharge for 1...2 hour faster than it can with 2-core cpu installed. Saying as 3740qm owner.

does anyone recommend a good system

Windows 7. W10 is a piece of s**t. Also you can migrate with Acronis True Image. Or just leave old SSD and replace dvdrom with new one using caddy.

What cable am I missing?

https://www.aliexpress.com/item/4000671206562.html some adapter like this and an ATX power supply of course. It will be cheapier if you buy pcie riser for mining station and find some dead usb3-expresscard adapter, that needs to be modified to be a plain passive adapter

For merely adding more monitors, is an eGPU recommended

You can use internal (and, probably, simultaneously docking station too) displayport freely. AFAIK nvidia's 6*0 cards doesn't support more than 2 monitors at a time, and summary surface resolution is the same, so if you planning to use only eGPU solution as multimonitor driver, you'll get only connections without any dp->someport convertors. As for egpu+integrated mixed usage idk, i'm not an egpu setup owner.

see, I use mine as a desktop replacement, it sits with the cover closed plugged into a 27 inch 4k monitor, wireless mouse and wireless full sized keyboard.    only time I open the cover is when I need to use the power button if for some reason I get stuck and can't start the rig from dead.

Used 2570p dock stations in the local stores are pretty cheap nowadays. I've buyed a dock for 2560p for $10 and don't open the lid about 4 months in a row when used it as dedicated workstation - dock have its own power button. Must-buy thing as for me.

back cover removed

Just for fun removed the bottom cover when compiling something... Got temperature drop from 90 to 75 celsius almost instantly, that's really a lot. Sadly, i don't want to drill the cover or use the nb without it, looks like performance limit to 99% is the only solution for me. With 3210 (i've installed my 3740qm back) i had ~70 celsius and 15W power consumption max without perf limit. Looks like cooling system in my nb can't keep cpu at 80 degrees when power consumption is >20W. Probably better plates resoldering to the heatpipe can give some cold (they was warm at compiling), but that's a tricky operation.

@Andrew479 here is mine coreboot build 4.10-dirty, looks like that it was the latest. Sadly, i've not found environment where build was done so i can't provide a config.

Of course, external programmer is needed.

Can you tell me how to downgrade the bios? Or send me a link in this article?

Unfortunately, i can't give you the full instruction nor say it will be 100% method. You have two options: try to downgrade from Windows or prepare a efi-compatible usb stick with a flasher module, bios image and signature files for this image, and then select the BIOS Update in a bios. HP made this method very complicated due to lack of documentation. Here is an example, but probably it incomplete.

High possibility that there is no downgrade option - as i see users with probooks cannot downgrade by the official way.

Some instructions then?

If your laptop have the latest bios, then descriptor overriding method is not for you - i've wrote earlier about this stuff. You need to downgrade or patch the descriptor with external programmer.

Look for the generic build instruction at the coreboot wiki, it's easy to build (easier than extract the needed firmware parts from HP's bios). Probably i have a backup copy of the coreboot, will look tomorrow, but take a note that acpi implementation there is unfinished and you'll get some troubles in Windows (i'm just switched back to the patched f73).

Just decided to swap a stock i3 back since i don't need i7 horsepower at this time, and that's what i'll got from liquid metal installed six months ago. Other than lack of contact, seems like dried alloy formed an increase in the size of the processor die, that means something (die or/and the heatsink) isn't flat. Honestly, i can't recommend to use LM, there was not much boost in the temp stability compared with GD900 even when LM was really liquid ¯\_(ツ)_/¯.

Hi,

haven't been here for a while, thinking the folks have moved on to newer models, and wow, modded bios? Nice!

 

Anyways, I managed to get another 2570p, but with set bios password which is unknown.

Since HP no longer does the smc.bin recovery, is there a way how to clear the password by other means?

 

Edit: I can't seem to find the bios file outlined in the above post. Was it removed?

It's here. But take a note that in your case moving the nvram section probably will also keep a password, thus you'll need to initialize system information with manufacturing tools. You also can just close manufacturing mode without setting any information, or flash an older (f.34, if i remember that right) bios dump without any modifications (of course system info will be different then).

What do yo mean by modern eGPU ? modern eGPU need thunderbolt. But you always can use expresscard. It works with some performance loss. I tried rx 580 and gtx 1060

I mean out-of-the-box support for the fresh GPUs to work through EC without any scripts. AFAIK main trouble was dedicated memory capacity that can be shared with the eGPU. Now we have ability to succefully patch any EFI module including DSDT.

Probably bios can be patched for the modern eGPU support now?..

These requirements are only for emulator with W10X, not the system itself. Also W10X is only for tablets, revived "Courier" project, not for traditional laptops or mainstream PCs.

You still can make a software-based RAID by windows partition manager btw.

I had 2 of those (same chip, I do not remember the firm, I do not use it any more), the one failed after some days or it was problematic from the beginning. Similar issues with you as far as I can remember with a hp 8710w, and then 2570p. Check settings about USB power management and disable all about this device from the Reneseas driver and the windows device manager. Somehow I have updated firmware without problem, alternatively try to update firmware on a different notebook, but there always be a chance of hardware being faulty.

Can you dump the data from 8-pin EEPROM of the working one, please? Well, i've tried to update firmware with disabled controller and it works now, thank you!

...it works like crap.

Ok it is clear now.  Strange choice by hp... wasted SATA3 speed on a slow DVD device

Because DVD is installed as Extension Bay device, and probably HP made some original HDD/SSD caddies for these laptops.

Guys, is there any owner of USB 3.0 "AKE" expresscard adapter that based on the uPD720202 chip? I've received one from ali, but cannot get it to work on Windows (error 10) and also cannot update the firmware (update tool just hangs). In linux it works after manual firmware upload, but only upon reboot. I want to try upload a dump from a definitely working
card.

I was reading up on the cooling ideas everyone has come up with, and I was thinking about taking an SSD casing off to where its just the PCB. It gives enough room to fit a whole second fan!

Main problem is insufficient for the full 35W load heatpipe, not the fan.

Guys, did your elitebooks going to sleep correctly at 0% charge (when battery is discharged)? My EB awakes instantly after being put in sleep. Bios 73 nonwhitelisted.
