Sony :: Vaio Z Series Manufacturer's Battery Life Claims Mystery
Jul 23, 2009
I've had eye on Z Series for couple days, but there exists a mystery I couldn't figure it out.
I've searched this forum and the net, still no answers.
On the sony's official USA website (www.sony.com)
Sony claims VGN-Z790 CTO has upto 7.5 hours of standard battery life.
However, other preconfigured Z Series laptop such as VGN-Z790DND, VGN-Z798Y/X, VGN-790DLX, VGN-790DKX, VGN-Z790DMR, and/or VGN-720D/B has upto 6 hours of standard battery life. It's mystery I was unable to figure out.
what's difference between Z790 and Z720? (I mean fundamental differences like circuitry design or expansion limitations such as maximum ram support and so. Couldn't figure this out... probably one of those model number decryption wizard would know it.)

First time poster, long time viewer.
I was just wondering if anyone experienced a battery increase after down-grading their Vaio Z from Vista/Win7 to XP? If so, by how much?
I'm currently holding a Z710dd (canadian vaio) with a standard battery with windows 7 installed. I previously had a netbook that lost a good hour and half from Windows XP to Windows 7. Even after disabling a lot of the windows aero mumbo-jumbo and themes

I recently purchased a Vaio VGN-SR390 with the "9 hour" battery. I understand you never get that. But what I think is odd, is that no matter what settings I change, including WiFi on/off, it *always* says 3:55 to 4:00remaining with 100% charge. (I haven't actually timed it on the clock, though.)
Questions:
1) Is this what other SR owners are getting? about 4 hours...no matter what
2) How do I make sure bluetooth is off (haven't been able to figure that one out)
3) Should I see the battery life increase with reduced display brightness, Wifi off, etc?

I own a vaio Z620d and I'm trying to do a clean install of windows vista business. I downloaded all the latest drivers and utilities from sony support site but whenever I finished installing the Sony utilities, I'd get this error complaining about my battery is not supported/authenticate. Even though the battery is the sony one from the box itself!
I know that you can prevent the ISBMgr from launching in the msconfig, but I do not want to do that. As I read from a post that the ISB utility controls the FN Keys and Eject Button.

I just ordered a Vaio TZ2500 Premium with the dual drives. It's intended to replace a MacBook Air. While I like the Air a lot, I just can't get used to its big footprint and short battery life. My school's library is pretty old and wasn't really built to accommodate lots of laptops, and often it gets really difficult to find an outlet. I was wondering, what kind of battery life should I expect from the TZ SSD+HD with standard battery?
My usage is very light. Most of the time I'm just looking at PDF's, maybe running some light stuff in Matlab, and Office and Excel 2003.
My other question is, has anyone tried Windows 7, and if so, do all the drivers work correctly?

I ordered a VAIO Z series with i7 620M chip thinking that it was a Quad core Intel chip. I discovered this morning that is a Dual Core chip. At first I was bummed and was thinking of calling SonyStyle this morning to see if I could change my order altogether.
After researching a bit more....this chip apparently has performance close to quad core chips, (and in some tests it is faster), with much less drain on the battery life.
As I placed my order I asked about the battery life with the large capacity battery option. I was pleasantly surprised to find out that the life expectancy with this configuration is approximately 8 hours! So, I have ordered the laptop of my dreams...a high end performer with great battery life.

i saw that there are 3 available processors on sony z series.
1 - Intel® Core™ 2 Duo Processor P8700 (2.53GHz)
2 - Intel® Core™ 2 Duo Processor P8800 (2.66GHz)
3 - Intel® Core™ 2 Duo Processor P9700 (2.80GHz)
the 3 processors will give me enough power, but i travel a lot, and i care a lot about the batter life, so which one is better for the battery life on z series?
hardware configuration to get the longest possible battery life?

I had a question on the SSD drives used in the FW590 CTO (configure-to-order).
I know that they have a 128GB option and also a 256GB option for their SSD drives and wanted to know the make/model/manufacturer of the drives.
As we know, there is a world of difference between the performance of the various SSD drives available, with the Intel models being the highest performing ones, while some of the other SSD drive models being pretty poor from a performance perspective.
I talked to Sony support who expressed complete ignorance on the make/model/manufacturer of the SSD drives employed in the FW models (VGNFW590 CTO is the model I am looking for) and thus was wondering if the folks on the forum know the details on it.

Several times I charge the laptop to full and turn it off. When I turn it back on moments later, it shows the battery at 75-80% and it always does this.
I call up customer service (only to find out that they are a bunch of retards because they always refer to their "manual") and they say that this is normal. Which I think is total bs, because they specifically state 3-4 hours of battery life

I bought Z500 last week and I am facing problem with the battery life. I charged the laptop for 12 hr for the first time. The battery discharges within 2 hr every time. I just browse internet or watch movies and the battery life is far below the expectation.
Â
There are two power plans - Balanced and Power saver and I do not see any difference in either. What is wrong with my laptop battery.

My friend and I both own Y510p laptops, but for some reason his battery will last an entire game of use and (very) light gaming, e.g. Binding of Isaac. However, mine only lasts about three hours on the Power Saver setting. I've even removed my SLI GPU to test it and un-overclocked my CPU/GPU.
Y510p - i7 4700MQ (Overclocked to 3.6GHz), SLI GT755M, Corsair Vengeance 16GB 2133MHz, Samsung 850 Pro 256GB, MyDigitalSSD SuperBoot 128GB, Intel Wireless-AC 7260, Windows 7 Home Premium (SP1)

Since I'm using LAN internet, My X1 Carbon is always connected to ThinkPad Dock at home use. In addition to connect the internet, the Dock is always charging my battery. AFAIK, the battery life will be shorten if it's always charged/plugged. Its better to work on battery after 100% charged and return to charge if asked to.
I just worried, is connecting to ThinkPad Dock after 100% fully charged can shorten X1 Battery Life?Â

I have a Thinkpad Twist and after updating the Lenovo Settings Dependency Package to 1.3.0.24, I no longer have the 'Automatically optimize for battery life' option in the Lenovo Settings app, i.e., the battery is always fully charged.
Â
I would like to use the battery optimization option, how do I get this function back?

I'm looking for a new notebook at the moment, and it might well be the Z21MN/B. The trouble is that I am pretty suspicious about the battery life specifications. I just want to make sure that the 6 hours battery life in stamina mode are not some developer's wet dreams but a fact.

I am trying to decide if the P8400 is worth the money in terms of battery life. The P8400 uses 25w as opposed to the T5800 that uses 35w. So a 10w difference. But as far as voltage range, the P goes up to 1.250v

I have a 4 year old vaio vgn-sz110b with windows xp home.
My battery wear indicator according to mobilemeter is 11% wear.
With windows xp I get 2:30 -3 hours of battery life.
I decided to bite the bullet and finnaly get windows 7 pro.
I created a seperate partition for windows 7 so I can dual boot windows xp/7.
After installing a fresh copy of windows 7 and most of the essential sony programs I decided to test out the battery performance and silly me, I really thought windows 7 would improve the battery performance but the results were absolutely disgusting.
With my fully charged laptop, I unplugged it and watched a movie to see how fast the battery would drain. Normally on my XP OS I would get 2:30 hours of watchtime. When the movie started I looked at the clock and it said 1:20 pm and I took a mental note of that. Shortly after the film the battery baloon popped up saying that the battery had reached critical level. I looked at the time and it said 1:40, I laughed thinking it ws just a mistake. Then in less than 3 minutes my laptop went into sleep mode!.............

I used to get 4-5 hours under Windows Vista. Now using Windows 7 Ultimate Edition and I'm lucky if I get 2-3 hours. The Sony site has no Windows 7 drivers for the SR190.

I am considering the two following models: SR290 and Z540. My question relates to the overall build quality of these models as well as battery life with the extended battery.
Basically Im deciding between these 2 and a lenovo. The lenovo is heavier than both, is well made, and has ridiculous battery life. Just curious as to how the sony's stand up over time.

I did a search and read various thread on the older Sony Vaio Z battery life. However, these are all in the year 2008 and pre Windows 7.
Vaio Z battery life tests
Vaio Z reviewers getting 9hr battery life!
I do a fair bit of transatlantic flights. So I'd like to know what battery life I can get with the Sony Z890, Windows 7, with all processes such as WIFI, Bluetooth etc turned off and being used in word processing and reading mode using the integrated graphics, with brightness at 50%. SLOW is fine as word processing is easy.
Anyone has a sense of the battery life I should get?
What if I turn on WIFI and use it as a netbook for surfing at airports?
I can't seem to find a recent discussion on battery life. The 2008 threads has a huge disparity with some people claiming something like 9 hours doing basic stuff! Hard to believe but thought I'd check with you guys.

What exactly does that mean in SIMPLE terms. Sony makes it all confusing and i'm like ? I don't know if i should get an extra warranty or if the Manufacturer's Limited Warranty is enough for now.

I'm wondering if the Blu-ray optical drive (Panasonic UJ-232A) of the (old) VAIO Z series will be able to fit into the (new) VAIO Z series? I would really appreciate it if anyone is able to answer my question.
The reason I'm asking is because I'm seriously thinking of selling my VAIO Z690 & just buying the base Sony VAIO Z (VPCZ112GX/S). I may just be able to afford that base model & the icing on the cake will definitely be the UJ-232A drive being able to fit into the (new) VAIO Z series & work.

So I bought a Sony Vaio FW-340DW for school which is the lower end with the X-Brite Eco screen. However, I have noticed something about the battery.
When I'm on the Vaio Optimized battery plan, I get 2.5 hours of battery life. But, When I switch the battery plan to Maximum Battery I still get 2.5 hours

I have a Vaio CR-190 and am having battery problems. Over the past couple months, my battery would show a full charge when plugged in, but when I would unplug the computer the battery would literally drop from 100% to 80% and began dropping futher. A few weeks ago, the battery would drop from 100% to 50% or so when unplugged and the battery would quickly drain. Recently, however the battery holds no charge at all and the computer will only run through the a/c. My battery management utility shows an X through the battery and says there is no battery detected even though the battery is properly installed. Everything else on the computer is running fine. I'm just looking for some advice on what's the best steps to take next. I've read that Sony has had some problems with batteries suddenly dieing and wondering if that's what it sounds like. The battery is from Sony and is the extended life larger one if that matters.

i have a Sony Vaio laptop that seems to have a good battery but after i use it on battery for 2-3 minutes it stops .
What is very strange is that in those 2-3 minutes the battery shown as available is draining like 3-4% per minute and the laptops stops and doesn't want to start on battery although it shows over 80% still left .
