The IBM PalmTop PC110 Using PS2.EXE: Power Management

PS2 Command categories

Power Management

_@BATTery

Values: Standard  or  Other
Type: advanced

Tells the PC110 whether you are using the standard 1100mAh IBM battery, or a different one. Affects the reading of the battery charging guage when the battery is fully charged - higher capacity batteries will read less than 100% charged when charging is finished. At this point, issuing the PS2 _@BATTERY OTHER command should sort that out.
 

LCd

Values: x (where x is 0-17 minutes)
Type: basic

Controls the time to wait whilst the PC110 is idle before turning off the screen backlight. Note that the display is still active; without the backlight it is very hard to read.

Setting LCd to a value of zero disables this feature.
 

OFF

Values: none
Type: basic

Puts the PC110 into standby mode.
 
 

_@OFF

Values: none
Type: advanced

Causes the PC110 to power off immediately.
 

ON

Values:  AT yyyy-MM-DD HH:mm:ss  or  AT HH:mm:ss  or  Clear (where yyyy=1995-2099, MM=01-12, DD=01-31, HH=00-23, MM=00-59, ss=00-59)
Type: basic

Sets a time and date, or just time, at which the PC110 will turn itself on (and boot off whatever devices are visible!). This is a single setting, but if you omit the date, then the PC110 will switch on at the specified time each day. So yes, you can use a PC110 as a power-managed alarm clock!

Clear disables this feature.
 

PMode

Values: High  or  Medium  or  Low
Type: basic

Provides simple control of the power management when running from batteries. High, Medium, and Low refer to preset combinations of values for POwer, LCd, and SPeed.

Note that when running from mains power, High is the assumed setting.
 

POwer

Values: x (where x is 0-99 minutes)
Type: basic

Controls the time to wait whilst the PC110 is idle before entering standby mode.

Setting POwer to a value of zero disables this feature.
 

RI

Values: Enable  or  Disable
Type: basic

Controls the PC110's response if it is in standby and a phone call is received. If set to Enable, the PC110 will resume from standby mode; if set to Disable, the call will be ignored.

Note that for anything to happen when this is enabled, the PC110 must come out of standby mode with a program running that is ready to accept and handle the incoming call - this would allow you to set the machine up to be an answering machine, or fax machine, depending on that software's capabilities. Also, remember that if this function is disabled, and you are near the PC110 when it rings, you can still pick up calls by flicking the microphone switch across even if the machine is in standby.
 

SPeed

Values: Fast  or  Medium  or  Slow
Type: basic

Controls the processor speed. I believe the choices equate to 33MHz, 16MHz, and 8MHz.
