dv2000z vs. dv2000t battery life

I bought a dv2000z a few weeks ago, played with it for a while and loved it. Super fast, sleek, and did most everything I needed it to do. The only problem I could see was that the battery life stunk. I only got about 2 hours under pretty conservative usage (i.e. internet browsing, music, and a few other common apps). I am returned it for the intel version (t2500 @ 2 GHz) so I could improve the battery life. By the way ... HP customer service is outstanding, seeing that I bought the laptop direct from them. Easy switch and they even gave me some discounts. I was also lucky enough to wait until they offered a discrete graphics option. Can anyone give me a good estimate on the battery life of the Intel system? I hope it is better seeing that I just switched. I got the 6-cell battery.
Thanks!

 

i have the T2300E DV2000T and im easily getting 4hrs of battery life.

 

Would it really be possible for the 'z' and 't' to have 2 hours difference in battery life based on a different processor? I have a dv2000z and have really enjoyed it. I have kept track of the length of battery life yet, although I know I have had it run on battery power for well over 2 hours.

 

I realize that battery life is really all relative (what programs are running and system configuration). My system was configured with the AMD X2 TL-52 @ 1.66 GHz, 2 GB of ram, 100 GB HD, and a few other things. I know quite a bit about system resources and how to configure them for max battery and I was still only getting 2 hours and 15 minutes at the most. Granted, I was using wireless internet, but I still should have seen more power. If anyone else has had different experiences with the "z" model, let me know. Maybe I had a dud. CNET backs up my experience with this review.

I am glad to hear that the Intel based system is a little better. 4 hours is more than I need. I am really an AMD fan and hoped to see a better showing. We'll see what the months ahead will bring.

 

Whats the rating/capacity on the 6 cells. I have the same spec as you except that I have a 12 cell and 60GB HDD and I consistently do average around 5 - 5.5hrs with Wifi on & brightness set to the lowest level. I'm surprised most people report the 6 cell to last only 2hrs. I was expecting it to be atleast 2:30 - 3:00hrs.

 

the rating is about 4:15 min. That is impossible. if you think about it ... the 12 cell should run exactly double the 6 cell. That means that your dv2000z with a 6 cell would get about 2.5 hours. I wonder why it is so low. I think that AMD is still figuring out how to do dual core in a laptop.

 

I got around 2 hours 40 minutes on my dv2000t. Decoded DVD, web surfing, e-mail and listening to music.

I had wifi left on, but at most I'd guess that would add perhaps 20 minutes.

Not sure how someone could possibly get 4 hours with a 6 cell, but I guess if it's configured differently....

by the way, I had a dv1000t previously, with a 12 cell, and somehow got 7+ hours on that machine!~

 

i get that 4hrs on a 6cell while browsing the web and firing up a game of pinball.
noone else is getting that with their dv2000t?

 

I still haven't directly monitored what I am getting out of my dv2000z, but it seems incredibly short, all things said and done. I've been hearing about how easy it is to exchange them (they even let you keep your old one until the replacement arrives, correct?). Do you think they'd let me exchange if I have reformatted the drive? I heard that breaks warranty, but I don't know if that's true or not.

 

Of course they will still let you exchange, even after a hard drive format. I'm telling you, my exchange was ridiculously easy. I am very pleased with the whole process. I just wish I could get some definitive info on the Intel system like there has been on the AMD. I think CNET is waiting to test the new grapics card option build, with the NVIDIA GeForce Go 7200. I just wanted to add. I have talked to a few others about their new laptops, i.e. Dell, Sony, Toshiba, I am very pleased about the dv 2000 series.

 

I am getting 3 hours with the brightness low and minimal wireless. I haven't previously heard of anyone getting 4 hours on a dv2000 with a 6-cell. Lucky you domoMAFIA! ;] I really like my 'z' so far, very quiet and fast. I would like something more like 4-5 hours, but I'm not sure that is possible with a 6-cell. I'm not convinced it would be worth it to exchange for a dv2000t.

 

Seems 2000t battery life really vary much. Whose result is the most ideal? Now 2000z seems very stable, 2:45 or slightly more. Why 2000t guys got so much different?

HP spec. it as 4:15 @ 6 cell. Could it be the battery defact?

 

I really think that the AMD system did not get a fair shake with me. I should have kept it a little longer. The battery life was not that great (as said before 2:15-2:20 at best) but my complaint was the performance. See the previous posts on the CNET review. It was not up to par for a dual core. That is the main reason that I switched to the T2500. I think the battery life will be better. We will see. I am hoping for 3 hours but would love to see 4. I think the centrino will do this better than the X2. We need to see actual times, with some benchmark standards. Let's say: internet use, music, and other downloads. Also one test could be: DVD play without quick play in use. Post your times.

 

Thanks for the reply. I figured it was a silly question, but I wanted to make sure. I agree that the dv2000 series is great though, I love everything about this notebook, other than how often I have to charge it. I guess I'll be calling HP tomorrow.

 

Any exact battery times yet?

 

I actually wrote HP's CEO to request they offer an 8 or 9-cell battery for the dv2000 series. I got a call a few days later from a product developer at HP and he said it was certainly within the realm of possibility that such a mid-size battery could be available in the future.

It seems like most people, 't' or 'z' are getting 2:30-3:00 hours. It would be nice to get 4 1/2 hours, but I'm not sure how much more I need. Thankfully there are plug-ins all over my campus, so I'll rarely have to be unplugged.

 

That's a good sign. But how far would be the future? I don't think it is matter of design, but the deal with battery vender. For almost the same weight, the battery could be vary from 6 cell to 8 cell, or 4000mAh to 4700mAh.

 

I timed my laptop for the first time last night and this is the result: I was doing a research for school on the internet through a wireless network with brightness in low and I got 3 hours 5 minutes before the laptop switch to "hibernation" with 6% of battery life left.
I have a DV2000T with the integrated GMA950 and factory bloatware (60 processes) still running in the background. I mention the bloatware because I believe that after a fresh XP install the battery life could extend for another 20 minutes, maybe?

 

This was with a 6 cell?

 

A 6% hibernate is really conservative setup. Usually I will set to 3%, and it is possible to have another 15~20 minutes.
3hrs 15 mins is probably a typical value.

Anyone from AMD side under same condition?

My ML-37 got 3hr 5min with excellent undervolt figure. 2000T's score is good to me, but not that great as in HP's spec.

DV2000T, is your battery 4400mAh? or 4000mAh? This confusion happened in V2000Z case. It should be marked on the battery.

 

I would like to see some "z" times reported. I also wonder that now HP has added the new graphics option of the GeForce 7200 if battery time will go down slightly. DV2000T, sounds like a good test. 60 running processes is quite a few and so I think there is hope to squeeze out another 15 or 20 min. I also wonder what DVD life will be. The drive itself should be pretty efficient but I don't know.

 

I monitored my battery time tonight on dv2000z, under somewhat similar conditions: Brightness set to 5 (or medium), and mostly just web surfing, aside from playing a handful of MP3s via iTunes as I browsed a music site at one point. My results: The machine got to 2 hours and 15 minutes before shutting down at 3%.

Not exactly impressive, compared to the over 3 hours on the Intel version. I haven't called for an exchange yet though, as I'd like to see if anyone responds about the upgraded graphics card (which I would definitely choose) significantly eating into some of that 3+ hours. But right now I'd say if I can get another hour out of the other processor, then it hardly seems worth it to keep the AMD.

 

Hey, zygrot
Have you tried undervolt twicking? I was wandering if AMD lock its lowest voltage. Core Duo lock it at 0.95v. I hope AMD leave an open door for their fans.

 

It already runs at the lowest voltage an AMD K8 cpu could. 800MHz @ 0.8V and 1.6GHZ @ 1.075V. So any undervolting will not be that useful iun terms of battery life. maybe it might reduce the heat out put when running full speed, but it definately wont make much difference.

 

miner, I was asking if AMD really locked their 800MHz at 0.8V as the lowest? Intel locked their highest clock 1.6G at 0.95V and people can't get anything better. I just don't have anything from AMD people.

Now, both Intel & AMD don't have feature to turn off one core on the fly for power saving. Undervolting seems to be the only way out. If not, then that's the end of story. AMD doesn't have any plan to roll out the improved cache yet. Even running in single core mode, Intel will get advance with bigger cache.

 

Are 't' users really getting an entire hour more than AMD dv2000s? It sounds like everyone is in the 2:15-3:15 area. I have a 'z' I can mess with it tonight and see what I get, but I got 3 hours just doing word processing and music. If intel is getting an entire hour more, why would they even sell the AMD? ;] I'm not sure I can exchange mine though, I'm in the middle of writing a research paper.

 

WiFi power management might be another issue for Intel getting advance over AMD. My 3 hrs ML-37 is under no WiFi condition. Broadcom may loose some point to Intel.

 

I saw a user opinion over at CNET; he stated he was getting 2:38 with an Intel dv2000 with the brightness very low and using WiFi. I'm not convinced it is worth an exchange to possibly get 20-30 minutes of battery power.
I'll wait it out for an 8 or 9-cell down the road. ;]

His virus scan is actually battery eater, somehow could run 30 mins in high speed.

8 or 9 cell? I don't think it will be there till next year. Or they roll out a new plan to surprise me.

 

Battery life is a big deal but the "z" is also scoring low in the performance marks. I wouldn't expect this from AMD but CNET does report a dismal showing. Would intel be any better? I have never owned an Intel machine. I just got the shipping info on my T Model with the following specs:
Genuine Windows XP Professional
- Intel(R) Core(TM) Duo processor T2500 (2.0 GHz)
- 14.1" WXGA BrightView Widescreen (1280x800)
- 128MB NVIDIA(R) GeForce(R) Go 7200
- 2.0GB DDR2 SDRAM (2x1024MB)
- 100 GB 5400 RPM SATA Hard Drive
- HP IMPRINT Finish + Microphone + Webcam
- LightScribe Super Multi 8X DVD+/-RW w/Double Layer
- Intel(R) PRO/Wireless 3945ABG Network w/Bluetooth
- 6 Cell Lithium Ion Battery
- Microsoft(R) Works/Money
- Genuine Windows XP Professional Backup CD

I am anxious to put it to use and find out for my self how much the battery will do, how much the processer will do, and what this graphics option can do.

 

That is a really highend configure. 2.0GHz/2.0GB, Oh my.

 

I have played with Vista enough to know that in about a year (if it ever is released and generally accepted) we will need all the power we can get in a notebook. By the way, Vista DRAINS!!! battery life like none other. I mean it is really mind boggling how much the beta version uses battery. Yet another reason to figure this whole thing out.

 

Like other test run that I read. Vista occupies 1GB memory without even doing anything. HD cranking a lot for just swapping virtual memory in and out.

 

I don't have either system, the dv2000t or the dv2000z, but i stumbled upon this forum trying to decide which to buy. I was leaning towards the 'z' version, but with the battery issue, im not sure now. i was also wondering could the difference be caused by the video cards? Intergrated graphics would take up alot less battery than non-integrated. The intel 't' version has the Intel GMA 950 graphics, while the AMD 'z' has an ATI card. Does anyone have the 't' model w/ the nvidia, because i have a feeling that that would be closer to the 'z' model. Also i'm concerned w/ performance, does anyone have any major performance issues with the 'z' because im on a budget and really dont like integrated graphics and the 'z' w/ ATI is alot cheaper than the 't' w/ Nvidia.
Thanks.

 

hi dave32392, I guess you're wrong, dv2000z series come with Nvidia Geforce Go 6150 which its an integrated and discrete video card, it has 32M of VRAM and take 92MB from system memory.

 

I have the dv2000t 2.0Ghz/ 2Gb Ram, Nvidia 7200, w/ a 12 cell. In the last 75minutes I've used exactly 25% battery so that would put my 12 cell at 5 hours. In that time my screen is set to the 3rd notch from the brightest, Wifi on, active on the web downloading and browsing, and installing software for my all in one hp printer while uninstalling other softwares.

Hope that helps for the battery comparisons.

As for performance this thing didn't even skip a beat. I'm very pleased so far with my purchase.

Super pi to 2 Million--> 1min 12sec

 

Oh, no. This is far less than HP spec. 8 hrs. Even 2 hr 30 mins for 6 cell is far less then other 2000t GMA 950 users.

Would this prove two things:
1. Either Go 7200 or 6150 cost much power than GMA 950(Intel has its trick saving power).
2. For CPU only, AMD is really the same as Intel. If the same GPU equiped, the battery life is not much different.

 

thats what i was thinking, can anyone else confirm this?

 

I have a dv2000z with a 12 cell battery and get about 5 hours on a charge. I no the 2000t will get at least another hour and a half more battery life. The z is a lot slower then the t because the processor is slower. I had the 5000t and 5000z and the 12 cell battery in the t was 1 hour and 45 minutes longer the the Z.

 

Well, integrated may have been the wrong word choice, I guess i should have said non-3rd party, basically i meant a different chipset than the motherboard, anyway, more to the point, i thought it was an ATI card, but whether it ATI or Nvidia, the 3rd party seperate card may be the culprit for the extreme difference in battery still.

 

Doesn't the speed difference depend on the config? Wouldn't a AMD Turion X2 2.0GHz (availible on 'z') be faster than the Intel Core Duo T2050 1.66GHz (availible on the't')? or am i mistaken?
My question was is a AMD Turion X2 1.66GHz have much less performance ratings than the Intel Core Duo 1.66GHz, or a AMD X2 2.0GHz any worse than Intel Core Duo 2.0GHz??

 

The X2 and the Core Duo are more less comparable based on clock speed. The 1.6GHz(2X512k cache) X2 is comparable in performance to the 1.66GHz CD. The X2 wont get the same performance as the CD in every benchmark but the average performance is comparable to the 1.66GHZ CD.

My V3000z with the 12 cell battery averaged around 5.5hrs. My dv2000t(Go 7200) shoudl arrive next week and will run some benchmarks and test the battery life and see how much I am going to get.

 

My AMD dv6000z fetches 2h 45mins.

 

Do you own Intel stocks???

 

Hi guys...

Seems like end of AMD X2 in notebooks atleast for the next 2 quarters. When core2 duo comes in Notebooks by next September , at almsot same price as current core duo's, it will be value for money, in terms of battery life and 64 bit support. Thou SantaRosa will be the mainstream by Q2 2007. Initial Merom versions are one meant for transition with compatible sockets.

Im not sure what **** the AMD guys were doing this whole year, after introducing that power hungry mobile chip (I may say renamed desktop chip)!!. Also who needed 64 bit copmputing this year.! They dont have even introduced an optimized version later... Didnt lower the prices when compared to the extent Intel did. Now the intel lappys are becoming cheaper !!. Im sitting handcrossed for the early release of core 2 notebooks today at Intel ceremony. HP guys, please get us core 2 - DV2000T

RR

 

I do agree that Core2duo mobile will be nice, i might have to hold out till then. Maybe ill fix up my old dell a little and just save up for a nice new core2duo when they come out.

 

my dv2000t wikth wireless on 768 memory and 1.66 processor t2050 only gets about 2 hours with the 6 cell... quite dissapointing, the 12 cell lasts me about 5
