dv5z and dv5t battery life

Hey guys,

I'm considering between the dv5z and the dv5t and wanted to know what type of battery life people were getting with the high capacity 6 cell. Is there any difference between the two models in terms of power consumption, GPU aside?

Thanks.

 

intel chips are usually better in power consumption then AMD chips.

 

Intel has something called Centrino (2), which contains certain components of the PC for battery optimization.

Intel may be a tad bit more, but I think a majority of the users here would prefer Intel over AMD. I mean at least right now anyways. The AMD dual core CPUs haven't been performing very well.

 

I don't think thats completely true.

Obviously Intel CPUs perform better than AMD CPUs right now, but that doesn't mean AMD CPUs doesn't perform very well.

They do the job they are designed for.

You should get better battery life from an intel based notebook (dv5t).
But and AMD based notebook (dv5z) will be cheaper. And if you're going for low end graphics, you will get better performance from an AMD based notebook than from an Intel based notebook.

Usually a dv5t, will get like 30 minutes more of battery life than a dv5z.

But a dv5z with a similar configuration (clock speed, ram, HDD, etc) will be like $150 cheaper than a dv5t.

i think u can buy another battery with that money (i will say 2 batteries)

 

I guess it's all up to what his intended use of the notebook happens to be.

I was comparing AMD to Intel. Sorry for the misconception.

 

I have a dv5t with the T9400 which is the fastest intel processor currently available. I also have the nvidia 9600M GT graphics. Dont order this combination if you are looking for good battery life. With the high capacity battery it lasts only 2 hours for just general email and websurfing stuff. Thats considerably lower than the test reviews and also lower than AMD machines. Just my 2 cents worth

 

The T9600 at 2.8Ghz is currently the fastest Intel processor that HP offers for its "Home and Office" computers.

With a high capacity 6 cell battery you should receive a much longer duration of battery use than 2 hours. You must be traveling away from the charger while the battery mode is set to High Performance. In order to fully achieve the 3 hours and 30 minutes duration you need to set the mode to Power Saver. That does some mambo jambo, and in layman's terminology just cuts the processor in half and lowers the FSB along with dimming the monitor to allow for longer battery life. There are a few other things that it does, but listing all of them could take me a while.

Overall, I prefer an Intel Centrino based computer versus AMD/ Puma. I've used a DV6700Z and own a DV9700T. Both of those computers perform great for normal everyday computing. However, heavy multitasking and higher performance was reached using the 9700 with the Intel based processor.

and that's just my 2 cents.

 

I wouldn't doubt it, as the T9500 is faster than any Turion available on the now-defunct dv6700z.

 

My bad, its a typo. I have the T9600

 

no biggie

 

my dv5t with t9400 cpu, 4gb ram, 9600m GT graphics, and with the system set on 'power saver' won't go past two hours of battery life with the std 6 cell battery. This is with wireless on and surfing the net/typing documents. Any ideas as to why this is the case?
Thanks in advance. Joey.

 

i bolded the answer...

 

So there's no such thing as decent battery life with this setup? Yes the cpu is one of the more powerful penryn's with a 35W TDP vs 25W for the P series, but it's not like this cpu is hugely inefficient? And the GPU would be idle while doing what i was doing. I'm just curious because a pcmag.com review lists the battery life at 3 hrs 12 minutes according to mobilemark2007 for the same cpu and gpu dv5t. Laptopmag.com also lists the battery life as 2 hrs 45 minutes for the same cpu/gpu but with 2gb of ram, it specifies that wifi is on. So i'm not sure why mine won't go much past 2 hrs, the screen is about as dim as can get and i'm not doing anything intensive. How much greater capacity is the high capacity 6-cell anyways? Thanks again.
Joey.

 

Which processors did they review? I believe the P7350, P8400 and P8600 all use 25W versus the 35W of the T9400 and T9600. That in itself would drain more power.

The 9600m GT was optimized for mobility just as the 5100 AGN card is as well. However, the 9600m GT is more performance which results in lesser battery life.

 

In the above two reviews i mentioned, they reviewed the 35W t9400, 2.53ghz, the same cpu i have in my dv5t, as well as the 9600m GT. Just wasn't expecting battery life to be so short when not really doing anything intensive. Still absolutely love the laptop, pity can't get wsxga+ screen in aus if anyone had a wsxga+ screen that's too much on their eyes i'd be willing to swap? I think i'm dreaming there though lol...Thanks for the replies .
Joey.

 

Shame you couldn't get the WSXGA+ screen, it is noice!

 

the WSXGA+ screen is the only reason im even buying from HP

 

So is the P8600 (2.4 GHz) better than the ZM-84 (2.3GHz) in terms of gaming? I heard the new centrino 2 kicks AMD's azz... plus if I overclock my processor will that help with crysis warhead? I have the 9600m GT. I don't wanna really overclock the graphic card unless I know if it runs cool. I know the processor runs comparatively cool in the DV5T from HP... plez help

 

I am certain you can't do that with dv5's or any HP laptop...

 

For what it's worth, I get about 6 hours on the 12 cell battery on my dv5t, P8400 (25watt, 2.26Ghz centrino dual), Intel 4500MHD GPU, running xp pro sp3 with the wireless on constantly, doing general computing/web research (not gaming or playing DVD/CD). Power saver mode set to max battery, and I do dim the display more when on battery.

 

The key here is the integrated 4500MHD graphics.. that will save globs of power compared to a dedicated nvidia option. The other thing that will take a bunch of power is BT. I kind of wish I ordered my laptop with the x3100 for the added power savings and less heat/fan noise along with not worrying that my 8400m will fail from the faulty solder that nvidia used on it. But then I would have gave up the hdmi. I think today its possible to get a 4500MHD with hdmi correct?

 

Mine has HDMI
