I am considering a blu ray laptop. HP's DV7 comes with a 128MB dedicated video at Best Buy. The DV7 at Walmart comes with 1GB of dedicated video. Will the 1GB video be that much worse than 128MB for battery life?
The BB Laptop with 128MB says 5hrs 15min, the WM laptop does not say.
I am considering a new laptop. The HP I am consdering has ATI Mobility Radeon HD 4200 graphics with 128MB cache memory. The other I am considering is the Samsung R580 which has a smaller screen, smaller battery, but 512MB dedicated video. Since the HP has an 8 cell, it will get beter battery life.
So, the 4200 is integrated into the AMD Turion chip, yet has 128MB memory onboard for the graphics chip whereas the Samsung has a separate GPU?
Both laptops have bluray and are within $50 of each other in price.
I'm interesting in buying a Dell E6400 and I would like to know the battery duration time different between using a Mobile Intel Graphics Media Accelerator against using NVIDIA Quadro NVS 160M?
Another question regarding performance, is there a visible performance gap between P8600 and P8700 CPU's?
1.I really didn't find much info on the (now not so) new white unibody Macbooks, expect some items for sale. And please, don't tell me that just buy the aluminum model for the extra $200, my question is strictly from an engineering point of view: heat. We all know aluminum Macbooks are quite hot, right? But how does the white unibody compares to the aluminum regarding heat issues?
2.What might be the reason that the whole bottom of the white unibody contcts the table beneath it, compared to the aluminum model, which has four rubber contact points on the four corners?
3.On the other thread I read a dedicated graphics card does not really add to battery consumption. Can you confirm that?
My main usage profile is office, web and seeing (HD, if available) Youtube videos. This one is rather a 15" vs. 13" Pro question, and half hypothetic. Let's say, all things are being equal on two models, the processor none the least, the only differences are one model has the integrated Nvidia, the other the integrated Intel plus discreet Nvidia combo, which one would serve me better, regarding performance and battery life? The discreet graphics would at least turn on when playing the HD videos?
4.Running native Windows (7 or XP) still suck on Macbooks, because of the drivers?
I had purchased a new Laptop ModelNo.HP 15-d002tx with NVIDIA GeForce 820M DDR3 1GB Dedicated Video Memory.
Despite successful installation of all necessary drivers I still could not see the Dedicated Video Memory being displayed as 1GB.
The latest Graphics Drivers installed are Intel HD Graphics 4000 Version- 10.18.10.3621 and NVIDIA GeForce 820M Version-9.18.13.3788. My Operating Sytem is Windows 8.1.
I have g6-2293SA laptop, it has Intel HD 4000 Graphic Card. When i look for Dedicared video memory it only shows 32 MB. But when i bought the laptop it was written upto 1.65 gb dedicated Ram.  how to increase the Dedicated video memory.
View 7 Replies View RelatedI have a g6-2002au notebook, running Win7 home premium 64bit on dual core 64bit cpus, 2.7ghz clocks and an AMD Radeon 7520G gpu, that is mostly used to preview (for a class) movie projects created in a video editor. And for video project files - stored on a usb stick inserted into one of the usb ports - that have a playing time longer than approx 4 minutes, the play presentation runs for a while and then becomes stuttering - pauses the image for a while, altho the audio continues, then the video seems to catch up, and after a short period repeats this stop and go activity. Like the editor keeps running out of data faster than its work space is filled up.
Â
I sourced equivalent (to the original brand and specs) RAM memory to increase the installed RAM to 8Gb without apparent impact on this. A change of memory stick type - usb2 to usb3 - worked a bit but the issue remains. And disciussions with others using notebooks - Toshiba's actually - did not have this problem.
Â
The dedicated video memory in the machine is 512mb (windows display settings details), and this probably isn't enough for video editing. With 8Gb of RAM now available, there should be plenty to enable me to increase the amount dedicated for video editing. Changing that seems to be a bios function, but there isn't any apparent/accessible setting in the Insyde F.03 bios on the machine to enable me to do that.Â
Â
So, the questions are,
1. Can I increase the dedicated video memory on this specific notebook?
2. if so, how?

Following the excellent flipfire's undervolting guide and inspired by Silvr6's experience with undervolting his dv2, I decided to give it a try and...I was able to increase the battery lifetime from almost shameful 2h 25 minutes to 3h 30 minutes for mpeg 2 play, or even to 4h 20 minutes (light browsing and lots of reading). So, you get at least 25-30% more battery lifetime. This makes me like my dv2 a lot more!
Perhaps, it's the noted AMD's tendency to overvolt their CPUs, perhaps something else, but I was able to get the following 100% stable (in my case) voltages:
4.0x-0.6875 V
4.5x-0.7125 V
5.0x-0.7250 V
5.5x-0.7500 V
6.0x-0.7750 V
6.5x-0.8000 V
7.0x-0.8000 V (yes, it’s 0.8V again)
7.5x-0.8250 V
8.0x-8.5000 V
these voltages are stable for my particular CPU; yours might be slightly lower or higher. For example, Slvr6 was able to get a bit lower with 4x – 0.675 V. Read the undervolting guide!
But I hope that the table above will encourage you to try the undervolting (btw, unlike the overclocking it’s 100% safe), since the benefits for dv2 and AMD’s “neo” are so dramatic!...........
I'm thinking of the following configuration:
8730
DreamColor 1920x1200
QX9300 processor (quad core)
Quadro FX3700
Anyone have something similar (even if one component is off) and can tell me how long their unit lasts on battery?
I'm thinking of jumping on the 8730 deal that's going on and battery life is the main thing that would make me choose this over something else.
(I had an 8710 with T9600 processor and the Quadro FX3600 and it got 3.5 hours on power saving profile. Wondering if the QX9300 kills battery life, because a Dell M6400 with that in it gets only 1 hour 45 minutes.)
I am considering buying a 8530w with a intel x9100 and 7200rpm drive. What kind of battery life can expect from this with power save mode on doing web work or watching a blu-ray disc?
How much time do you get with your 8530w?
how do you like the 1900x1200 screen?
i have purchased a new HP laptop DV5 1215 TX [url] [basically Intel c2d, 2.2ghz (t6600), nvidia 9600M GT] when on its 6cell battery , it only gives about 1 hr 40 mins, regardless of use, i.e. playing crysis or running internet.Is it acceptable for these specs or is there genuinely a problem with the battery?. in either case bluetooth , wifi was turned off, dvdrom was not in use as well.

Pretty nice overall, however the battery life is horrendous!
High performance power plan w/ default settings for the plan, with wireless/bluetooth on, web surfing, some youtube playback = 90 minutes!
balanced w/ same use as above =120 minutes
power saver w/ above: 145 minutes. (just shy of 2 1/2hr).
The unit was on display for about 1 1/2 month and did have the battery in it from the start, and was always plugged in. Did this damage the battery , or is it just normal for this high of battery consumption?
Got a new laptop a few days back (6730b), which is alot nicer than the nx7400 i had. When i got it, it came with vista business and a whole load of 'bloatware' i didnt need. so i did as i normally do and formatted the pc and re-installed vista (although XP was very tempting). I finally got round to getting everything how i want it but i've realised since formatting the battery life seems to be less than it used to be....
before the format, when the battery was full it would say i had 4hrs+ of battery life (i even remember seeing it say 5hrs once). Now it says 2hr 30 mins on 'HP optimized', 2hr 45 on power save!
I just got a new envy 15 the other day. There is a high pitched noise that is kind of annoying, but I'll be using the laptop at a cafe 90% of the time and probably won't notice it. I'm pretty happy with the laptop otherwise.
Does anybody have any tips on increasing the battery life? Other than screen brightness and lowering the "maximum processor state" in the power plan, are there any other settings i should be aware of? I've read posts claiming to have increased battery life of an i7 envy 15 to 4-5+ hours. I think I'll be pretty happy if I can squeeze 3+ hours on my i5...
Is this due just because of LED? Seems pretty crappy the 14" gets about 2 hours on a 6-cell battery and the 13" gets 6.
I wonder if they are planning on redoing the dv4 line to get LED displays if this is the reason?
I have the following set-up on my DM3T that is getting 4.5-5 hours of battery life at a maximum with light use, ie: lowest screen brightness, wifi off, word processing. I am not running any background programs (anti-virus) or anything else that is resource intensive.
SU4100 1.3ghz 2MB L2 cache
4gb DDR3 ram
320gb 5400rpm HD
Why am I getting less than 5 hours of battery life on a unit with low specs that is supposed to get "up to" 10 hours?? Is this consistent with what everyone else is getting? Battery bar currently says that my battery's 'full lifetime' is 4:58. I just returned an Acer timeline that had the same processor and 3gb of ram instead of 4, and that thing was getting 8-10 hours easily.
I spent a couple hours reading through dozens of pages in the 3 separate HP Envy 15" Owner's Lounge threads and couldn't find a definite answer to the following questions--there was usually conflicting info.
In total there's over 1k pages, so despite considerable time spent perusing and searching perhaps I missed a definite answer somewhere in there. So hopefully, it's okay if I ask this outside of those threads for a conclusive answer:
1) Every review I've read mentioned the heat issue with the i7 system. Has anyone read an official review or gathered a consensus from users if the i5 version of the 15" model has lesser heat issues?
2) Does the i5 have graphics switching? And does the i7?
3) The i7 has very short battery life, which dissuades me from getting it. Is the i5 any better? What sort of usage are most i5 owners getting out of it?
Playing an SWF (flash) file with video embedded in on AC power looks great. When unplugging the power and working on battery, the same video becomes very sluggish and unwatchable.
I've checked all power setting and ATI control panel and changed all "Optimize video on battery" I could find.
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

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...
I have Dell XPS 1530 and I have 2 problems,
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?
Why is the Studio XPS 13 so terrible on battery life? ~2.5 hours on power saving mode, 1 on high-performance. I believe the Sony Z rates around 3-5 hours on power saving, as does the Latitude 6400. Is it normal to have this low of a battery life for a 13.3"?
What is draining all the power? How does the Z pull 4-5 hours on its battery life?
I don't want to shell out for a 9-cell and also have to deal with the added weight... but this is ridiculous.
Also, are there any new deals for the 9-cell batteries?
Here a bit of summary of how to enable some advance power plan settings, the highlights are disabling the core parking override and max % of unparked cores.
-Windows by defaults keeps at least one logical core active per physical processor core. With the nehalem architecture parked cores consume almost no power.
-Also keep in mind if you set max unparked cores to 50% it may still activate all cores because 50% of 8 hyperthreaded cores is 4.
-You can use resource monitor to see if cores are parking
-once you've done the registry tweaks below you should have some extra options in your advanced power plan settings
-Setting you power plan back to defaults nulls you the changes to it is harmless and reversable if you are careful
-If you are not comfortable making registry changes don't do this as you can really screw your computer up, if you mess up the wrong things in your registry
Open Regedit (type regedit into the startmenu search box)
Expand location to:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlPowerPowerSettings54533251-82be-4824-96c1-47b60b740d00
In order to enable some advanced power plan settings you will have to rename the REG_DWORD "Attributes" to "_Attributes". This one it own does not change how your computer runs, it simply adds an extra option into your advanced settings for each power plan
Here are the relevant registry keys:
0cc5b647-c1df-4637-891a-dec35c318583
lets you set the minimum number of unparked cores (I set this to 25% for power saver)
3b04d4fd-1cc7-4f23-ab1c-d1337819c4bb
turns on additional processor throttle states, caution this throttled my laptop to the point that it was almost unusable you can change the attribute to _attribute but leave the power plan setting disabled.
447235c7-6a8d-4cc0-8e24-9eaf70b96e2b
Sets the processor power state when parked, I think the default is ok
5d76a2ca-e8c0-402f-a133-2158492d58ad
Option to Disable processor idle states, not really relevant on a laptop
a55612aa-f624-42c6-a443-7397d064c04f
Processor core parking override, this one is key, it you don't disable this in your power plan settings you will only park "virtual" cores
ea062031-0e34-4ff1-9b6d-eb1059334028
Maximum number of unparked cores, this is useful to put your computer into "dual core mode" in power saver if you set this to 25% or 50%

My battery charger doesn't charge and the blue light isn't turning on.
Is it safe to assume that it is dead?
Are there any tests I can do to verify if that's the case?
I've had it for a year and 3 months, is that the typical life of a battery charger?
