Sony :: Which Processor Is Better For The Battery Life On Z Series
Aug 27, 2009
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'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.)
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 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 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 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'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 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 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 am looking to buy an SR. But anybody who has any data or experience in comparing the two please chip in.
I will also use RMclock and want to be able to under-volt the CPU. which on the two is more compatible with rmclock?
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!.............
tell me the real world battery life of the Sony Vaio Z such as performance vs stamina mode for the Core i7? or continuous internet surfing or continuous movie watching
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.
I just got a new sony vaio F-series with the new i7, it was really fast, took me about 2 minutes to get to startup screen and log in. But all of sudden after two weeks it started to slow down
( I didn't download much, and I scanned with both avg and adaware and no viruses or problems found).
Also, my gadgets instead of appearing on the sidebar like normal appear in the middle of the screen randomly.. I am extremely pissed because I have heard such good review
I'm looking to replace mine P8700 cpu with the one from T9x00 series but i'm concerned about the temps afterward. So please tell me your temps in idle/full load if you have ......T9600,T9800,T9900 or P9700 . If you have some other T9x00 i'm interested in those to.
I had replaced mobo on my dead SZ 4 series (don't ask why) and couldn't stop there since I was in the move thus consequently contemplated about possible upgrades. For now I settled for fan, WLAN card and CPU upgrade. If it works well, I might install SSD also.
1.Fan Modification
As you all proud SZ owners know, fan is very noisy on this machines so it made me think if there is any possible modification to reduce the noise. Since the BIOS is controlling it there is not much to do on the RPM part (in win at least, but more on that later) I settled for a fan and fan casing swap from SZ 4 to SZ 7 series.
In the photos you can see that fans, fan casings and heat-sinks are of different design. Besides design differences, voltage and the amperage are the same, 5V-300mA.
Only way was to install the fan and the casing of the SZ 7 heat-sink to my old one as one of the heat-sinks bolt bushings is off for a few millimeters.
There has to be some care exercised when prying off the fan casing, some heating was required from the aluminium side on three pins were casing is attached.
Not to be simple, the difference is also in the inlet hole. One on the SZ 7 heat-sink is bigger and off centre compared to SZ 4s. Had to do some filing there, to match it to the size of the new fan. Fan of SZ7 is not bigger, it is due to different design of the fan eye and its volutes...................
I am looking for real world feedback for the 6 cell battery on the XPS 16. This would be mainly word processing and Internet surfing, with the screen at about 1/2 brightness
I'm new to OS X, got my MacBook the other day, and I can hands down say it's my favorite OS I've dealt with. It's so much simpler and just plain awesome. Okay, I'll ask my question before I get carried away...
So, I did some searching on Google after I noticed that my battery likes to hang around 99%. Apparently this is common. My question is, is this a BAD thing? When I see 99% I'm picturing that the computer is constantly pushing power into the battery so it can reach 100%. I mean, isn't that how fires start?
Simply put, is my MacBook trying to charge the battery consistently when it is not at 100%?
every time I'm running my uMBP from battery, I'm constantly checking the amount of time I have left and trying to figure ways to increase that time. Yes, CONSTANTLY. Whenever I can, I'm using the a/c adapter.
Even though I may see 6-7 hours left, I'm still not satisfied.
And just about every time I am running the battery, I'll open up Coconut Battery to make sure I still have a 100% charge hold left....even though my umbp is 7 weeks old with only 4 cycles...
1 – Keyboard. When I type cursor seems to jump around a lot. I would be typing and suddenly the cursor is in the middle of the previous sentence and it’s a mess. Is that something common, is that me or is that something I need to call Dell?
2 – Battery life is extremely short. I hear of such thing as deactivating your video card ( I have GeForce 8600 GT) and that supposedly helps you with the battery life. Does this laptop offer such opportunity?
