Mobile PCs Tomorrow
What are they?
Getting Personal and more Mobile
Smaller, lighter, more ergonomic
Carried and Used all day
Always connected
Natural Input (pen and voice)
Shedding Vestigial Compromises
Larger, more powerful, impressive feature list
Performance rivaling modern desktops
Full-range media experience
Mobile PC Challenges
Battery
Life
CPU
graphics
io
Rad
DVD
HD
Battery And Power Technology
Original Equipment Manufacturer (OEM) ask
Refine the Traditional Details
Fully Implement ACPI methods and Mechanisms
Plug current leaks on motherboards and peripherals
Be smart about power plane control and separation
Modify backlight intensity to suit ambient light levels
Examine Your Battery Strategies
Balance Big Batteries versus Extender Batteries
Look at Warm Swapping and Fast Charging
Look to Technology (Future)
Fuel Cells: Available now, some airline concerns and heat
Micro-Turbines: Technically viable, noise and heat issues
Photovoltaic solutions: Viable today, outdoors only
Battery And Power Technology
Advanced Configuration and Power Interface (ACPI) ▲
Windows codenamed “Longhorn” Requires ACPI
Non-ACPI HALs are not included in Longhorn
No Support: APM, EISA, Hardware Profiles, ISAPnP
Retired Processor Drivers: amdk6.sys, p3.sys
Intel Mobile P-III SpeedStep supported by ACPI 2.0
Hybrid Sleep Combines Standby and Hibernate
Users just put the PC to ‘Sleep’
System saves hibernate file, then enters Standby
Normally resumes from memory (fast)
If Standby loses power, the system resumes from the hibernate
image, without data loss or error
Eliminates S0 transition on S4 doze timeout
Battery And Power Technology
User Interface (UI)
Improved Management UI
Battery Meter is clear,
current, and more
informative
Power Management Plans
are Far More Intuitive,
Useful, and Accessible
Simplified Shutdown UI
Move to appliance-like
Power button
Promote Sleep as default
off state
Battery And Power Tech
Sleep reliability
Reducing Component Vetoes and Queries
See “Longhorn Power Management Update”
Failures Identified by the Sleep Diagnostic Agent
(as of March 15, 2005)
Bugcheck or Hang
during Sleep /
Resume Transition
25.72%
Component Vetoes
37.54%
Hiberfile Generation
Failure
19.32%
Unknown Failure
11.31%
Failure to Resume
from BIOS
6.11%
Battery And Power Tech
Windows Direct
Windows Direct is Microsoft’s means to quickly resume
directly to Windows-based applications
Example Launch to Application Scenarios
E.g., “media” button quickly starts a media player or shell from any
non-working state
E.g., Offers quick system startup from Standby, Hibernate,
or ‘Off’ (S5)
Mobile Users are Increasingly looking to carry and
use their Mobile PC just as they do a Cell Phone or
Portable Media Player
Implies expectations of near-instant system access
Features most resembling mobile appliance features inherit the
greatest user expectation for ‘instant on’
Processors, Chipsets, And Features
Processors
We finally have true Mobile CPU solutions
Faster and more power-efficient main CPU offerings
Faster and more efficient auxiliary processors
Multiple Vendors: Intel, AMD, VIA, ARM Partners, etc.
Breaking the “GHz = Performance” Myth!
Chipsets
Full featured and practical legacy reduction choices
Integrated graphics has improved…must continue to
Varied choices allow design teams to better
manage price and performance decisions
according to the targeted purchaser and/or user, and
the intended usage
Graphic Subsystems
Probably #1 Longhorn Mobile PC Question!
This is not as tricky as it seems
Modern Mobile PC graphics subsystems burn off as
many Watts as the primary CPU!
Changing: Performance != frames per second
Integrated versus Discrete Graphic subsystems
Performance == Fast, Power-managed GPUs!
The Longhorn Influence
Help ‘nudge’ the bottom performers up
Mid-to-High performance solutions are on target now
Users want a full and effective Windows experience!
Graphic Subsystems
ClearType
You Built It, They Bought It: Fully Utilize It
LCD Pixels have a finite resolution, why utilize just 1/3?
ClearType, a Microsoft Technology, is Built into the
Operating System (OS)
Enhance Further through the Power Toy and Web ‘Tuner’

Mobile Performance With Longhorn
Longhorn ready
Will Longhorn Run On Mobile PC Hardware?
Most of today’s Mobile PC Hardware runs Longhorn
More capable Hardware runs Longhorn better, or runs more of
Longhorn’s advanced features, especially graphics
The graphics experience varies per system capability
The Operating System will adjust the presentation complexity
As with any OS, you need comparable hardware to get a
comparable experience, Mobile or stationary
For the full-on, best possible Longhorn experience,
assume Mobile PC hardware similar to this
CPU – Mid to Performance class overall, nearer the high end
of today’s Mobile CPUs
RAM – 512 MB or better, for both desktops and mobile
Mobile Performance With Longhorn
Gauging it
WinSAT is Your Key!
ALPHA version of this tool is in the WinHEC
Longhorn build
Tuning and enhancements during the Beta-2 cycle
Key Longhorn Platform Feature Performance
Understand performance differences between models
Measure differences between configuration
alternatives
(I.e., Catch mis-configured DRAM using the memory
tests)
WinSAT Assesses a System’s
Graphics, Memory, Processor, and Storage
Also Subsystem Attributes, Features, and Capabilities
Data And System Security
Data and System Security
Absolutely critical to Enterprise solutions
Increasingly critical to Home Users
Physical
Hybrid ATA Hard Drive Solutions
Heads parked and Spindle stopped = lower crash probability
Saves 90% of disk drive power = approx 10% of power budget
Faster boot and resume times = Save disk spin up time
Malicious (or Capricious)
Taxicabs EAT laptops and Tablet PCs!
Hardware guarantees on the motherboard
See also Secure Startup session, for details
Summary And Call To Action
Utilize the tools and advances to meet
customers’ rising expectations
We all need to focus on addressing our
customer’s wants and needs
Build the best Mobile PC systems ever seen,
today…and tomorrow, together, we will build
Mobile PCs running the full Longhorn experience
to eclipse them!
Perfect the details and THRILL
your customers!
