  1. https://files.catbox.moe/09x0v3.jpg not really sure if blower hole needs to be reworked.
  2. 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.
  3. 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.
  4. @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. https://yadi.sk/d/MXnuzaKKEa0Bmw Of course, external programmer is needed.
  5. 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.
  6. 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)_/¯.
  7. 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).
  8. 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.
  9. Probably bios can be patched for the modern eGPU support now?..
  10. 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.
  11. You still can make a software-based RAID by windows partition manager btw.
  12. 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.
  13. 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.
  14. Main problem is insufficient for the full 35W load heatpipe, not the fan.
  15. 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.
  16. Recently i've found a russian review for the graphene thermal film (https://aliexpress.ru/item/32839728084.html review https://mysku.ru/blog/aliexpress/72798.html), it's effectively spreads heat all over the horisontal surface, possibly it can be used as additional layer for the cooling system by gluing to the heat pipe in several layers. Maybe someone already tried this?
  17. Just read the first post of the thread, there is a bunch of information about power economy (especially about aspm)
  18. There's not any screen available. Only one possible mod - install eDP panel with additional soldering (look previous pages).
  19. He can Just don't connect the third pigtail, i don't think that he will get any significally speed boost with it (additional 150mbps, and appropriate router is needed). As for wwan antenna, it's not for the 2.4/5ghz range, but still can be used if you didn't want to disassemble the screen for additional antenna installation.
  20. For that display screens from x230 only one possible solution available - you'll need to remove the webcam, make a new bezel and somehow mount screen into the housing case. Nothing found, but i've doesn't search anything in that way. It's true that cooling system is not effective for quads, i've got 95 degrees even with locked on x27 multiplier.
  21. Hello, how do you found that? Did you edited IFR section (or replaced from 8*70 PS module)? I see a lot of changes. Am i right that WWAN-device will be inaccessible then? I've noticed that Bluetooth option after removing according module didn't affect anything thought, maybe with WWAN will be same story. Well, there's no surprise. @juandante asked about msata-enabled RAID, maybe it's available now. Good work anyway. Only if pcie lanes is physically wired to the slot. @adrian_sa tested WLAN card already in the WWAN slot with no success. I've checked some schematics, pcie is wires into the same pcie pins that mSATA is used, so there signal commutator is needed. Dunno if it really exist on the motherboard side under the keyboard, but i think there is just no any option for combo cards in WWAN slot.
  22. mSATA expansion is interesting feature not because its something unusual but its offers additional storage space without need in replace main storage or use external storage with this notebook. Even if this technology is dead, **70p series that not much worse than modern businessbooks (except display) can be upgraded with this particular type of storage. In addition, mSATA SSDs now popular primarily on classified market with affordable price, that OEM samsung drives is exceptionally tasty offers. @Onoakino Sorry, but i don't have time for video records. When i'll get some free time I can make full image from F.34 dump if it's full, but if you guys is not ok with same serials then nvram still needs to be replaced. @invait53 did you check disk SMART's for interface errors? I've got DMA errors and fallback to 3.0Gb-mode on much shorter cables in times when i don't have internal SATA adapter.
  23. Is someone there have a dead battery for our laptop? I have a semi-failing battery (works fine but drops to 0% from 18-20%) and planning to replace cells with Samsung 35e. I've noticed that battery pack controller on Elitebooks less strict than most of ic's coming in batteries for consumer notebooks, there is no charging cycle counter and no wearing control, battery parameters are freely recalculating in both sides at everyday use, but will it get selflock when at least one cell is fully dead and no voltage remains on it or at least effective battery capacity is enough for 5 minutes of autonomous work?
  24. Just done messing up with bios write protection. PchBiosWriteProtect BIOS lock 00 B2 FE 48 81 C1 DC => 00 B2 FF 48 81 C1 DC SMI lock 00 B2 20 48 81 C1 DC => 00 B2 00 48 81 C1 DC PchSpiRuntime 00 00 B2 FE B9 DC 80 => 00 00 B2 FF B9 DC 80 Checked on ther F.73 bios version. Unfortunately, in F.73 bios FDO hotkey is banned - nb just turns off right after start, so additional flash descriptor region edit is needed. Here is patched bios section binary for your needs. It contains: no WWAN/WLAN/Bluetooth whitelist, no SecureUpdating module, no CompuTrace modules, BIOS lock removed, no_ASPM_bit in FACP is reset. No NVRAM. How to flash: Get a full dump of your stock bios, make a backup Extract the NVRAM section from it with UEFITool (BIOS Region => FFF12B8D-7696..., Extract as is) In hex editor open the full dump and replace bios section, start address 0xB00000 ($LOGO string) Replace the NVRAM section with yours in UEFITool (Replace as is) Edit FDT at address 0x60 00 00 0B 0A 00 00 0D 0C 18 01 08 08 => 00 00 FF FF 00 00 FF FF 18 01 FF FF And flash it with hardware programmer. Possible issues: don't know why WIn8.1 boots too long, because of edited bios, shrinked MEI or just because it can. As for mSATA, i'm not succeed at this time, maybe later. If someone want to try search where is satacontroller is initialized, here is the list with modules that different between 2570p and 8770w (don't checked bios versions though). 2570-8770 module diff list.zip
  25. Well, guys. I've successfully managed to get an unwhitelisted BIOS from F40 just according to @adrian_sa reference, and also shrinked the MEI firmware. There is two things to notice: 1. use UEFITool (non- NE Alpha -version) to drop unnecessary modules, and Andy's Tool to determine what modules is needed to be dropped. Last one reads module names better, but first one rebuilds modified image correctly. 2. Internal programming is impossible at this moment, since even after descriptor overrided there are some locked regions remains. But, forget about it - if you flash broken image, laptop will turn into aluminium brick. It even will not turn on. External programmer is needed in any case. But well, i'm not interested in a loss of bunch of time when trying to get mSATA to work by replacing modules from similar platforms. I've built coreboot with platform config modification - just replaced 0x33 for 'sata_port_map' to 0x3f in 'devicetree.cb' file for our notebook. And - yup - it works, mSATA is binded to the SATA port2, correct value is 0x37. If someone want to make it usable just as ASPM was done - you may use setpci and this file for reference, but more work than just 'setpci -s 0:1f.2 92.w=8337' need to be done there. Full SATA reinitialization in most difficult case.
