    I know it's a not very important issue, but I would enquiry HP about allowing BCLK overclocking. Of course, in order to use it with XTU. I realise, that we have genious Khenglish and his ME FW files, but.. I still haven't figured out how to enable the BCLK slider in XTU. It's a kind of a lottery, unfortunately.

    It could be connected with raising the max. TDP allowed by the BIOS.

    Oh, and maybe they would answer if BCLK OC affects EC PCIe frequency. Because if it does not, we would need only higher TDP limits to unleash the power of powerful i7 CPUs. This OC is really important for EC, because it could be the only way to increase eGPU bandwidth.

    Thank you for the suggestion. While I'd love to ask about BCLK overclocking I can pretty safely say running a BUS beyond it's standard 100Mhz will get a flat 'unsupported' response. Even the 45W i7-quad CPU upgrade is a bit touchy since HP designed and tested the system with a 35W i5/i7.

    Instead, Khenglish' 2570P BCLK ME firmware post advises:

    I do not know if this BCLK overclocking also overclocks the PCH PCI-E for eGPUs. It would be nice if someone could test PCI-E bandwidth in SANDRA with a BCLK overclock to verify if it does or not. If not I can provide an additional mod which definitely will overclock the PCH PCI-E.
    With the missing slider, does it occur with XTU 2.1 and XTU 3.x? It would be great if you can work with Khenglish to figure out what the 2570P limits are for pci-e overclocks. As you point out, success there would gain extra eGPU bandwidth.

    Maybe HP could at least tell us, if there is a point in looking for eGPU performance boost this way. If it gives us a 0% chance of overclocking PCIe, there's no reason to further investigate this issue, as I don't even have a i7 QM, which would be limited by TDP.

    Wasn't there a 2570p (somewhere on Ebay) with 45W i7? Correct me if I'm wrong.

    I tried every version of XTU. Reinstalled it dozens of times. Before the flash, there was at least a greyed out slider. Then, it disappeared and I can't get it to appear again. Khenglish said there's some voodoo needed to do it... so, it makes me wonder, why this reinstallation method worked for Aikimox.

    Yeah the BCLK slider missing is a mystery to me. After having to reinstall windows my slider is now gone and I can't get it back either...

    Worst case, please keep the WLAN disabled whitelist in future BIOS updates. I just tried an Intel 1000 and Atheros AR5B91 I had laying around. Both showed in the BIOS as TEST WLAN and showed in Windows. Safe to say that the whitelisting is broken or disabled.

    Great effort, M8! Alas, we all know the answer. If HP honors you with a reply, it will probably be somewhere in the "not tested, not supported, not designed, no..." ballpark
    I'd be surprised if the was a constructive and positive feedback from them (or any other vendor for that matter). Still, crossing fingers and toes wherever possible. Good luck!

    Here's a suggestion for you Nando4... now that you have HP's ear (temporarily at least), ask them to consider unlocking the BIOS for all discontinued Elitebooks (2530p, 2540p, etc.- obviously, the 2570p will soon join the list of no longer made Elitebook models). Ask for schematics for all discontinued models as well.

    Since the enthusiast community here is pretty self-sufficient in solving many of its problems (given the right tools), this seems like a reasonable request, and could be a nice public relations move for HP.

    In order to even have a chance for this to happen though, we should probably first demonstrate that there's an actual demand. Perhaps an online petition asking for these things. All current 25xxp users on the forums could sign it. Spread the word here, at NBR, etc and get a few hundred signatures. I'd sign in a heartbeat.

    Just an idea. But even if we only get the schematics, it'd be worth doing, no?

    I've added this and phillofoc's suggestion to the list. FYI: I have 2510P, 2530P, 2540P, 2560P leaked schematics already. Only one missing is 2570P which I figure will be pretty much the same as the 2560P except with a 16MB BIOS chip (not 8MB), has USB 3.0 as part of the newer Series-7 chipset and of course the Ivy Bridge CPU.

    As for non-whitelisted BIOS the situation is as follows:

    * 2510P, 2530P - whitelist disabled modded bios is available but only flashable if you have existing bios older than F.20. HP's newest F.20 or newer bios a trap to prevent rollback to the earlier modifieable bios. REF: http://forum.techinferno.com/hp-busi...html#post66863

    * 2540P, 2560P - not possible to boot a modded bios due to HP's RSA protection. Last I tested the 2560P had a WLAN whitelist active.

    * 2570P - oddly, the WLAN whitelist is either broken or disabled as discussed. However, WWAN and Bluetooth whitelist appear intact.

    WLAN/WWAN/bluetooth whitelisting is an effective built-in redundancy mechanism forcing users to upgrade their system to get newer comms standard support. Thankfully we 2570P owners with F.41/F.42 BIOS can upgrade to 802.11AC WLAN due to the disabled WLAN whitelist. Hope HP doesn't fix this and eliminate feature.

    Anybody with another Ivy Bridge Elitebook (8470P/W, 8570P/W, 8770W) want to test to see if the whole Ivy Bridge Elitebooks have WLAN whitelisting disabled? Maybe we are just lucky with our system?

    Hackintosh 2570p: OSX 10.8.5 on stock 2570p

    On a different note (and still showing the flexibility of these little units)...

    A few weeks ago over on TonyMacx86's site, user Tyraenor reported getting a fully running version of OS 10.8.5 (minus WiFi) on a 2570p.

    Just follow this guide: HP Probook 6470b

    Here is my selection in ProBook Installer:
    * OS X support kexts\4x40s support kexts
    * DSDT ...\ProBook...\4x40s Ivy
    * DSDT ...\Fan behavior\Readings only
    * DSDT ...\Display type\Low resolution
    * SSDT generator
    * System definitions\i3/i5 Ivy Bridge
    * Chameleon r2255
    * Optional hard...\EDID generator
    * Misc OS X fixes\Color profiles
    * Misc OS X fixes\Sleep fix\Sleep image fix (Just if you have an SSD like me)

    After doing this do not reboot until you installed the four kexts from the guide above (AppleHDA, Intel...Capri, Bluetooth, IntelE1000)

    That's it. Fully working 2570p 10.8.4 (except WiFi).

    If you want to update to 10.8.5 you need to do the following to get all working:
    * Reinstall ProBook installer like above (except Chameleon)
    * Reinstall the four kexts
    * Install IOBluetoothFamily.kext from 10.8.4

    Now you have fully working 10.8.5!
    Note it may be possible to get the WiFi working by swapping in an OSX compatible WiFi card - not sure if anyone's tried that yet (or if there would be whitelist issues). I assume you could just use one of those tiny USB WiFi dongles instead of going through that hassle.

    Again, if there's any interest in Hackintoshs here - this is pretty exciting news. Thought I'd mention it.

    I'll deal with it, but I'm wondering - has anyone here removed their 2570p optical drive and experienced much reduction in weight? That is, does the 2570p seem appreciably lighter without the DVD multi-drive installed? And - strange question, I know - is there anything else non-essential that can be removed to put this unit "on a diet"? I think shaving off even half a pound or so would make a noticeable difference.

    (6 cell 3520m 2570p owner)
    INFO: 2570P weight loss

    Almost missed this post. I too noticed a weight gain going from a 2530P to a 2560P/2570P. Difference now is that accompanying my 2570P is a smartphone which is great for quick internet browsing. The 2570P gets pulled out for more substantial work where I value the 2570P's desktop-replacement performance features and associated weight penalty over say say a light, nimble, underperforming ultrabook with very limited expansion/upgrade potential. The 2570P Quickspecs tells us:



    Easiest weight loss could be accomplished by removing the ODD, using a smaller battery and replacing a HDD with lighter SSD. Could even up-spec the battery to one 3-cells larger and omit carrying the AC adapter to bring weight down if the battery can provide the runtime you need before a recharge.

    If removing the ODD then the option of filling the space with an optical bay space saver as described here. Can also use an empty 9.5mm SATA optical bay caddy, best with a detachable faceplate so can fit the 2570P optical drive one for a perfect appearance. The benefit with the caddy being it's (1) cheaper than HP's plastic kit containing the space saver and (2) have the option to add a second SSD/HDD to your system. Only negative may be it might be a touch heavier than the space saver. Can even relocate the primary drive into the caddy thereby slightly lightening again and gain better weight distribution. Slightly lighter since you could then remove the primary drive bay caddy, SATA angle connector and a couple of screws. Though I doubt those items weigh in at anymore than 30grams. Small gains nonetheless.

    • HDD = 0.11kg / 0.24lbs (from M&S guide)

    • optical drive = 0.12kg/0.26lbs

    • 3-cell battery = 0.15kg/0.33lbs

    • 6-cell battery = 0.30kg/0.66lbs

    • 9-cell battery = 0.45kg/0.99lbs


    To drop more weight consider these, presented in order of practical impementation difficulty:

    1. remove blank plates: expresscard, modem

    2. remove unused internal modules accessible through easy rear service cover removal : modem, WLAN, WWAN, bluetooth

    3. remove your drive caddy by separating your SSD/HDD and taping it down instead. Consider deshelling a SSD for even less weight.

    4. remove silver keyboard overlay revealing the black base. Also a way of changing your 2570P's appearance.

    5. remove unused internal modules requiring disassembly: smart card reader, fingerprint reader

    6. drop cooling subsystem weight with holey bottom cover, heatsink mod & shorten heatpipe with repositioned fan (advanced)

    Location photos of internal modules are available at the HP Media Services Library.


    Lightening the AC adapter

    The stock 65W AC adapter is a pretty heavy unit. Total carry weight can be decreased by upgrading your battery to the next size up (+3 cells, 0.15kg/0.33lb), forgo carrying the AC adapter and recharge once back at your home/hotel/office. If doing that consider the battery life tweaks available here to extend your range. Other options:

    1. Use a lighter AC adapter accesssory specifically for our Elitebook. Note: 45W included in list for weight comparison sake. It's incapable of powering and charging a 2570P.

      HP 65W Slim Adapter AX727AA (0.23kg/0.49lb)
      HP 90W Slim Adapter BT796AA (0.23kg/0.49lb), pictured here against 90W Smart adapter (pandaleo).

      HP 45W Smart AC Adapter H6Y88AA (0.20kg/0.44lb)
      HP 65W Smart AC Adapter ED944AA (0.28kg/0.62lb)
      HP 90W Smart AC Adapter ED945AA (0.37kg)/0.82lb)

    2. use a shorter 1ft IEC C8 ended cable OR use a direct Cloverleaf to Plug adapter (UK).

    3. Apply figure eight (IEC C8) to cloverleaf adapter (IEC C5) and use a IEC C8 cable with smaller power socket end.
