Below I re-submit the questions I have for the 2570P engineers with the extra additions. There is no 12.5" 2570P Haswell successor, such as a ZBook 12, planned even after several attempts to request for one from Dion Weisler and Enrique Lores (notebook managers). Nor is there any planes to produce a systemboard that would allow 2570P owners to upgrade to Haswell internals. A shame as Apple's just-released Haswell offerings continue to include a 13" MBP for the optical drive. All others omitting an ODD which is where a 12" ZBook could get some traction.
Hence why the aim is really to maximize performance of the 2570P to workstation levels. Answers to the questions below would help with some of the discussion happening at 12.5" HP Elitebook 2570P Owner's Lounge
. Consider too 2570P designers are welcome to post their own personal research there that may help the discussion. I realize some answers of the intended modifications be best discussed outside of HP.
My contact details are xxx available during business hours GMT+10 (East coast Australia). Though you may find it easier to simply answer my questions via email.
Technical details requested about the 2570P
Physical hardware modifications/upgrades
1. WWAN slot extra lines
: If the 2570P systemboard factory unbridged tracks in the WWAN slot are bridged (pin 23,25,31,33), does it give a mSATA or mPCIe electrical link? If it's mSATA, does the BIOS make provision upon detecting it to enable the corresponding port? If it's mPCIe what port number is it? Based on the 2560P schematic
I'm guessing it's a mPCIe port1. Someone with a 2570P schematic could answer that question.
2. Better heatsink
: is there factory 2560P/2570P heatsink part that incorporates a second heatpipe for improved heat transfer? This would alleviate the need for heatsink mods, examples by Aikimox
& jacobsson's 'Anarchist'
to reduce fan activity or host a 45W i7-quad comfortably.
3. Backlit keyboard retrofit
: is there anything in the HP part catalog that would fit the 2570P chassis perfectly, with adequate length ribbon cable. I realize that would require 5V or 3.3V to be patched to the backlight connector. The '820 G1' keyboard looks like it might be suitable. REF: nando4
4. LCD panel upgrades
. We've had no success fitting the Lenovo X220/X230 IPS panel with wide viewing angles due to physical clearance issues. Is there any other wide-viewing angle panel that would fit in within the LCD bezel? Reference: bjorm
Or better yet any higher resolution panels (eg: Dell XPS 12.5" 1920x1080 LCD?). Higher resolution panels require a dual-channel LVDS electrical link which someone would need to confirm. Could someone review the schematic to advise? The 2560P had only single-channel LVDS good for 1366x768 but not higher so it's likely the 2570P is the same. REF: nando4
5. Schematics and non-whitelisted BIOS for discontinued models
: A.J requests ask them (HP) 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.
1. Fan noise
: can the fan RPM cut-in frequency be lowered from 3200rpm? It was necessary to do quiet_fan: 2x1N4004 diode mod (bjorm) &
: as a workaround to reduce fan RPMs including cut-in RPMs
2. Increasing CPU power limits
: can a BIOS be made to set a higher 45W (or completely unlocked) CPU power limits such that a user installed 45W i7-quad can be used at it's full performance? Currently the power limits are set to 35W which decreases the turbo max multiplier by 2 (200Mhz).
Some users are contemplating flashing a 8470/8570 bios with factory 45W i7-quad support and mSATA support to unlock these performance features. RSA bios protection making user modifications to the factory 2570P BIOS impossible.
If they did flash either of those bios, would it cause the system to hang?
3. Removing WWAN/bluetooth whitelist
: we've found that the wifi whitelisting appears to be disabled
. Can the same be done for the WWAN and bluetooth whitelists
in an updated BIOS ?
request: please keep the WLAN disabled whitelist in future BIOS updates.
4. Enabling ASPMs for better battery life
: can INFO: 33% longer 2570P battery life by enabling ASPMs and L0s L1 using software
be added as a BIOS option in an updated BIOS revision? Contrary to my initial findings, there is no negative side-effect with the SD/MMC controller. Insertion of a SD card into the reader sees it re-appear in Device Manager.
