Above X25M G2 benchmarks with "1011" and "1033" show the value of 0:31:1 54h (IDE Controller). The "1011" is the ~30MB/s write mode. The "1033" is full speed write slave write mode. See
here for full explanation. The 89/58 with 14-15MB/s 4kb reads is duplicated using a Marvell caddy and X25m G1

INFO: Extending Battery Life
Monitoring battery usage and cpu load
The u7600 consume as little as 5.8-6.2W during in idle with LCD brightness at 3 bars, wifi on and HDD in idle.
Here is another comparative u7600 system consuming 6.5W at idle. If yours is significantly higher at idle consider investigating any runaway processes or devices adding CPU load and reducing battery life with tools below. There will be some variation between 2510Ps as well, but you should definitely be < 7W idle.
Tools:
batterybar |
battstat |
process explorer
Suggested Power Saving settings
1.
X3100 graphics is set to
Maximum Battery. The performance settings appear to use 1W more power. XP X3100 4990 graphics driver caused unusually high cpu utilisation after ~3 mins of usage, so I rolled back to version 4926 found on a Lenovo website which has been very reliable.
2.
SoundMax audio driver
In XP I set it to
High Power Savings. Found this sometimes needs to be set to "None" then "High Power Savings" after a resume-from-standby otherwise it gets stuck in an intermediate mode.
In Win7/64, I manually press mute button on the touch panel to get some noticable power savings, though it was inconsistent. I uninstalled the the Sounddriver back to the Win7 default "High Definition Audio", then I disable it. This saved 0.4W at idle.
3.
4965AGN wifi driver
Set AD-Hoc power management. Set your power levels to the minimal needed to get a good signal in your area. Might also cause power spikes, so I disable then enable the driver.
4.
Disabled VPRO using 'hpbi103 write vpro.vpro_state disabled' as described
here. This then unlocks the "Network Interface Controller" enable/disable option in bios, saving somewhere between 0.5-1W power. With VPRO enabled, disabling the NIC in XP doesn't appear to offer same power savings.
5. Use an undervolted DC profile using the
2510P Performance Kit. So instead of running 0.9125V@x9 divider I run 0.8625V@x9 divider and all other dividers at the lowest 0.85V setting. Extends battery life and lowers temperature.
6. Apply
quiet_fan mod to decrease fan power consumption.
7. Install
flashblock Firefox add-on. Flash based pages kick up CPU utilisation/power consumption.
8. Have no battery-sucking USB devices attached when running on battery.
9. Install a
93Whr 2540P 9-cell battery offering a 12% battery life improvement with newer hi-cap cell technology than the 83Whr 2510P/2530P 9-cell, or 69% better battery life than the 55Whr 6-cell. See part number details for the 93Whr battery
here.
10. Perform
hw_undervolt to undervolt by up to 0.1375V.
Measured Battery Life
XP's battery life indicator oscillates based on instantaneous power consumption. It shows an unrealistic up-to-12hrs battery life. I don't bother to use it so have it permanently disabled. Instead I use BatteryBar whose historic measures accurately predict total battery life.
BatteryBar shows 7.5-8hrs total battery life from a 9-cell at 66Whr capacity when doing surfing/admin work. A brand new 83Whr 9-cell would give an extra 25% (2hrs), 10hrs total. That's with the Runcore ProIV ZIF SSD, no HDD in optical bay, wifi on, LCD brightness at 3 bars brightness in XP. Impressive for two-gen old tech.
