When the new machine was received, I checked out these features.
In summary, every one of the features that the machine was supposed
to have, performed as they should. However, a few needed software love
for optimal performance.
| Does it boot at all? | Box
|
| | Yes, it boots the installer and the installed
kernel with no problems. This is OpenSuSE-13.1 with kernel 3.11.10.
See the Setup page for how to turn off UEFI boot
and revert to Legacy booting.

whether or when it's used to produce output.

|
| | MATSHITADVD-RAM UJ8A7AS slot loading.
- Reading CD: OK (but an unknown kernel thread maxes out one CPU).
- Burning CD: 12x, 2.16e6 bytes/sec excluding overhead.
- Reading data DVD: 24x, 4.8e6 bytes/sec.
- Play movie DVD: Partial success, obviously codec problems.
- To signal the software to eject the disc, press the button
labelled with an up arrow, above the keyboard Esc key.

2.6Mbyte/sec = 20.8Mbit/sec
Theoretical maximum: 54Mbit/sec
|
| Bluetooth | Box
|
| | Intel Centrino Advanced-N 6235 (802.11abgn)
on USB. Works with headphones. Usual complaints about A2DP sound
quality, which is the fault of the algorithm, not the laptop or the
headphone.
|
| Other Features | N.T.
|
| | Has WiDi (wireless display) client.
|
| | WiMAX modem is mentioned but I see no trace
of it; maybe an optional feature.
|

- Bus 4: 2 of these slots as USB-3.0 (XHCI)
|
| Battery | Box
|
| | Lithium ion, capacity self-reported as
52.3 watt-hours. The life depends on the workload but is not much over
2 hours. Life under Windows is reported as 3.75 hours up to 5 hours;
maybe Windows is using some tricks that Linux doesn't know about.
|
| Power consumption |
|
| | Maxed out, 4 cores (37.0 sec to do 4 benchmarks) | 59W
|
| | Maxed out, one core (31.2 sec to do benchmark) | 45W
|
| | Idle (normal session, lamp at max) | 30W
|
| | Suspend to RAM (alternate 0W, 3W) | 1.5W
|
| Suspend and Wake | Box
|
| | It will suspend to S3 (RAM) and S4 (disk).
Onboard devices including graphics can suspend and wake successfully.
Hardware and software cooperate so when you close the display the
machine suspends to RAM, and it wakes when you open the display.
|

|
| | Wake up from S3 | 2 sec
|
