C2 vs. C1/B4/B3 vs B2

There has been some question about what might or might not work on  
different
builds of laptops.  The laptops MUST be running the latest firmware  
(q2d05 or later)
and a recent kernel for the following to be true.

Everything works on a C2
    with the exception of a few items in Trac and some yet unknown  
ones...

On a C1/B4/B3:
- There may be occasional crashes (possibly made worse by suspend/ 
resume)
    when the battery is running low.  Above 25% of capacity, or  
plugged into a power
    adapter, you should be OK. (#1835)
- There may be times when the WLAN (USB) hangs (possibly made worse by
    suspend/resume).  (#1752,#4476)
- Power cycling the DCON is liable to crash the laptop.  This power  
cycling will
   occasionally happen in response to a DCON bug triggered by
   suspend/resume. (#4479)
- Rare crashes may be caused by other sources during suspend/resume  
(Camera,
   SD card, clock settling time), some units (especially B3s) may be  
more sensitive than
   others. (#1835)

On a B2:
- All of the problems listed for C1/B4/B3 are present.
- The keyboard/touchpad may not be used to wakeup from a suspend/ 
resume. (#895)
- The DCON will glitch coming out of suspend/resume. (#947)

Cheers,
