Sony Vaio z13 model Standby time on Battery after Shutdown

Just wondering what you guys are getting on standby time after the battery is 100% fully charged than you Shut it down. I always shutdown the laptop and I had not used it for about a week and it would not turn on without AC plug and when it booted battery was at 0%. The Vaio center showed the Battery condition as Excellent. This is a new laptop with very little use maybe 6 hours.

My older Sony TZ model i can shut down and after 3 weeks it still boots on battery. I'm wondering if I have a bad battery on the new one or this is the norm with the Z13 model.


I looked and could not find anything about standby time within the specs so anything to cross reference with other owners is great.

Thanks

 

Anyone? The Sony tech was no help at all. This is something that has to be answered by other owners

 

It's been AGES since I logged in (and I'm only here after I noticed the Z series starting to disappear across the globe)...

I'm unsure if this issue is supposed to even exist on the 2012 lineup. The VGN-Z (and all 2008 models) suffered from a battery-drainage issue. That is, you do a full shut-down with a 100% charged battery, and 8 or so hours later in Windows (after a cold-boot) you're told the charge level is around 50%.

Sony actually responded to the complaints back then because (if memory serves correct) they were threatened with a class action law suit or something similar in the States and the UK. Their response was, pretty much, saying that the laptop uses FULL POWER (irrespective of what power plan you're on on shut-down) to boot-up, causing the unusual readings. But they never explained the aforementioned scenario; NO laptop sucks 50% worth of battery charge booting up. Even if it's been shut-down for 8 hours. People back then were reporting LESS drainage putting their VGN-Z on SLEEP rather than a shut-down or hibernate.

But yeah. People here back in 2009 till around late 2010 speculated and attempted all sorts of things to fix the problem. S4 states, potential hardware not turned off after a shut-down (eg, my VGN-Z makes a high frequency sound near the bluetooth card, but I've been unable to prove it on paper it's powered on after a shut-down. This is because Windows tells me it's not supposed to be; maybe a BIOS thing considering the Sony BIOS back then was locked down quite tightly, and still is I think).

Yeah. I've a Samsung R45 laptop from 2006 in the cupboard for if-everything-else-fails backup. I last charged it to 100% in January 2012 and booting it up just last week to update the OS, battery was reporting 40%.

EDIT - LOL. Forgot about my own sig. Been AGES like I say... Rachel (the mod), you still around?

 

I read some of those threads on here one is 74 pages alone, I was hoping to get first hand experience from other Z3 model owner so i can gauge how well the battery is performing and if it is in fact a problem or perfectly normal to drain at 10-20% daily unused.

Thanks for your input

 

Anyone else can contribute some standby times

 

I have a SVZ1311C5E and do not experience the issues. After putting it the shelf and leaving it unplugged for ten days while being on holiday, it showed 98% after booting up.

 

I don't get that kind of battery life at all with this laptop.

 

Is you battery still in excellent condition or worn out?

 

It is excellent, brand new laptop.
