WLAN drawing battery in standby

I just had a quick conversation with SONY, and they tell me that, on the SZ series, the WLAN remains on when the system is in standby/hibernate. As such, it continues to draw battery power.

They tell me that the only way to stop the WLAN from drawing battery is to manually turn off the WLAN via the switch.

It seems odd to me. Can anyone confirm this?

 

Oh! Now that makes sense! My S360 had an issue where stanby or hybernate would draw power FAST. And even when the unit was off it still draws power from the battery.

 

Why do people use stand-by when Hibernate does the same thing and at the same time doesnt use battery. I always use Hibernate and basically never used Stand-By.

 

because it wakes up faster. ever been somewhere you need to get your screen up fast?

 

On a stage giving a speech yeah lol. In those cases I just close the lid of my notebook and that way when I open it on the stage its just the way it was. Ofcourse I have the settings so that that nothing happens when I close the lid.

But yeah this uses way more power then stand-by.

 

Are you SURE hibernate keeps the WLAN alive? That goes against everything hibernate is supposed to do. In Hibernate, power to the machine is OFF, just as if the machine is turned off. I use hibernate a lot, and I haven't noticed any power drain while in hibernate. I guess I could see standby possibly keeping power on WLAN. It's kinda bad for battery conservation, but I could see that being overlooked somewhere in the design engineering process. Hibernate on the other hand, would have to purposely be set up to keep WLAN alive, and it just sounds like too much trouble for no good reason.

 

Hibernate in no way keeps the WLAN running, that im sure about. I totally agree with you ostack I use hibernate a lot aswell and it serves its purpose really well.

 

If I had to guess, I'd say it might keep it on in Standby (S3 or 'STR') but probably not in hibernate (S4 or 'STD')

Does the Intel wireless even have the concept of WOL?

 

You know, I tried using hibernate years ago on some of my earlier laptops, and it didn't work very well. The bus throughput, and memory speeds were so slow, that there really wasn't much benefit to hibernate. It took about as long to recover from hibernate as it did to simply start the machine from cold.
My D600 is also pretty slow, but it is still better than a cold start. But with my Averatec, hibernate was very quick, about the same as my SZ. The impressive part about the SZ is its 1Gb transferred from ram to disk, and it happens in under 20 seconds! And recovery from Hibernate is about 10 seconds slower. The Averatec is pretty fast, but that is only half the ram of the SZ. I'm curious what kind of Hibernate/recover times the guys with 2Gb SZ'z are getting.

Two thumbs up for Hibernate!

 

I have 2GB of RAM, and I RARELY turn my SZ160 off - I always use hibernate. Going into hibernation takes about 10 seconds, and waking up takes maybe 12-15 secs. As for this business about WLAN staying on during Standby/Hibernate - that's hogwash. I've used both standby and hibernate, and my SZ never keeps WLAN on. Maybe some of you have faulty machines that are not going through the standby/hibernate process properly, but mine works like a champ.

I'm absolutely amazed how IGNORANT sony's reps are about this machine, which is quite possibly the most popular laptop they have ever manufactured.

Oh, I forgot to mention, that Standby is faster than Hibernate to power down, but as far as waking up goes, the two are almost identical in recovery speed - I can't tell the difference without a stopwatch.

I had a s480(400 something) and got the s360 for better video. And BOTH laptop would drain for no reason. standby would drain like 1-3% per hour and hybernate would drain from 100%-80% in a day. And completely off would drain to 85% in 3 days.
Sony said this was normal for their laptops. Go figure.

Btw, I had dells, toshibas, etc. only Sony's had done this.

 

Yeah SZ is the best thing Sony has made so far IMO. I only hibernate never standby, takes roughly 10 secs to hibernate, while to come back takes like 8 secs to the logon screen where my SZ asks for my password or fingerprint
