Try fan_40pct in the revised

Modified HP 2510P BIOS
DISCLAIMER: Use these modified bios at your own risk!!
These modified bios have been beta tested to confirm they do not brick the system after flash. However you will be solely responsible for any damage to your computer system or loss of data that results from flashing or using of a system with a patched BIOS. These BIOS are not tested or approved by HP.
^1 (x) indicates number of bytes modified in original 2510P HP bios. F.0F is based off TTAV134's SLIC2.1+no_whitelist bios from here
YELLOW = recommended
*
SLIC 2.1: for Win7 usage.
*
no whitelist: whitelist checks skipped so can use non-HP wifi/WWAN cards as explained
here.
*
dual-IDA: Disables the EIST-lock bit. This means then
Throttlestop (TS) can do a dual-IDA overclock, gaining an extra multiplier and 10%-12.5% performance from any U7xxx/L7xxx 2510P. TS also unlocks extra overvolting range from 0.9V to 1.0V to provide higher maximum setfsb overclockability. L7xxx also gain a lower SLFM voltage floor for greater undervolting ability using TS. If you don't use Throttlestop then your system will run with the speed and power consumption as it did prior to flashing the dual-IDA capable bios.
*
quiet_fan: exactly the same as
quiet_fan's DSDT modifications but more conveniently located in the bios so doesn't require a DSDT override in Windows registry or Linux kernel. Can still use
quiet_fan's DSDT override if run multiple OSs requiring different fan load profiles.
*
pcie_ASPM: offers better power saving and eradicates a Linux dmesg warning as
described.
Installation
Windows users
Download package of interest in the
Version column on the right, double-click, extract to a desktop folder then run the HPQFlash file and follow instructions. The supplied HPQFlash is modified by TTAV134@mydigitallife to allow successful flashing of a modified bios.
If HPQFlash doesn't do anything and you see a LOG file containing an entry
WMI BIOS Flash function is not supported on this system, then install HP Quicklaunch on your system and try again OR perform a DOS based install like for Linux users below.
Linux users
Download and install modified rompaq from
here. Download bios file of interest from above, extract rom.bin from the ROM.cab and copy it as 68MSP.bin on your DOS bootable USB thumbdrive. Reboot using the USB drive and install bios using the rompaq utility.
Bootup error after flash
If you get a message on bootup
Your bios failed to complete the update. please ensure that you follow the correct procedures and try again. This may require two sequential bios updates to complete the process then apply mike60's fix
here of flashing back to F.0E, flashing the non-modded F.0F then flashing a modded F.0F bios.
Which modded bios am I using and why?
I'm using SLIC21+nowhitelist+dual-IDA+fan_30pct with a 5100AGN wifi card. I've previously been using setfsb to overclock my U7600-1.2 to 1.6Ghz (178Mhz@x9) and created the dual-IDA mod in the hope to take the overclock further.
Unfortunately my CPU is unstable at anything beyond > 1.66Ghz. Dual-lIDA mode's extra voltage not giving extension there. I can run Throttlestop, click EIST to use single-IDA x10 mode so some single-core apps will run at 1780Mhz (178@x10). The dual-IDA bios mod was not necessary to run my single-IDA mode though it doesn't hurt to have it available and other users can get benefit from this. My Win7 WEI CPU
score increased 0.2 points using single-IDA mode. The 178@x9 gave some intermittent video hangs on overclock, so I've gone to a rock-stable 160@x10 dual-IDA overclock instead.
fan_30pct is also now in my bios. No need for my DSDT override in XP or Linux and get a nice and quiet system. For the more heavily loaded Win7 I'm using the
fan_40pct DSDT override to avoid fan yoyoing b/w 30% and 55%.
Customising BIOS DSDT fan speed entries further (Advanced Users)
The place to tweak the fan speed settings further in the F.0F/F.10 rom.bin file is at:
@0x714B2: fan speed table bytes matching
quiet_fan DSDT fan speed table entries
@0x6EC50: recommended checksum correction byte to use
If you decrease the fan speed table entry values, then add the difference of their sum from their original sum total to the correction byte. This will ensure the total checksum of the DSDT table is zero. Otherwise Win7 will fail to boot with some ACPI/BIOS is not compatible type error.
Flash gone wrong? Use
Emergency Recovery. You must use a USB floppy drive. A USB thumbdrive doesn't work.
