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?
I know that everyone has different configurations and such, so while that does have an impact, I still want to know what is the general ballpark battery life you guys are getting. From what I am seeing, 2 hours is the average for the 6 cell, whereas the 9 cell is only 3?
I ask because as strange as it sounds, using BatteryBar indicates that the 6 cell that came with my 1640 has a capacity of only 5100mWh! That sounds very strange, because I know that on my XPS m1530, the 9 cell had a capacity of nearly 86,000mWh. I am having a 9 cell sent to me for my XPS 1640, and hopefully that will fix things. Maybe the battery's circuit board is reporting the numbers wrong/shrug.
I am strongly considering taking my laptop onboard to try and kill off a few hours especially as i have a good 100gb worth of films & series on it, but i want to try and squeeze every last drop out of the battery!
I will obviously be turning the brightness right down and turning off the backlit keyboard, aswell as wifi etc, but is there a way to drop the cpu speed to 15-20%, or whatever the laptop needs to run a film?
I wont need the full 17" screen, is there any way to turn off 3/4 of it so that i am only using a portion of it? if not is there any colour to use as the background that wont draw as much power, as im guessing fullscreen will draw more power.
I thought I would check how long the battery hold out on my new studio 15, which I got two days ago. Surprisingly, only roughly about an hour. Is this normal? When I just unplug the power cord, it says 3 hours.. and then the remaining time of the battery dropped quickly inpproportionate to the physical time past. The whole time I was just surfing the internet, IMing and playing music. The battery is 56 WHr 6-cell Lithium Ion Primary Battery.
I had to reset my Studio 1749 to factory defaults and now the option for "Dell Extended Battery Life" within the Dell Battery Meter is gone. I don't know what needs to be reinstalled in order to get it back.
These are the changes that might affect the issue:
- Installed a different WiFi-Card (Dell 1520)- Installed a different Tuner Card (Yuan, provided by Dell)- Installed Service Pack 1 for Windows 7- Flashed BIOS to A08- Updated all Drivers and Utilities from the Dell Homepage except for the ATI-Driver
I think it is a useful tool if you use your notebook on battery, because it is able to control a few options that are not available in Windows 7 default power plans.
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?
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%
I have a e6400 with SSD, a P series processor, LED screen and 9 cell battery. On the balanced mode, it is at 94% and 2h32m left. That sounds REALLY low to me. I have WiFi on, brightness up, etc. but still sounds extremely low.
i like having my m1530 on my lap (unplugged) in the living room while i watch tv/babysit so far i can only make it last 2 hours at the most(surfing the web,messengers) with the brightness 30% and powersaver mode.
well i was reading on the thread on how to underclock your cpu...theres a problem with that:
-numero first im too lazy (hurts my head when i try to understand the thread,hence the "[ADVANCE]" on the title ^^")
-numero dos having a t5450 on power saver mode (50% max perfomance) is slow enough... so i tried to look for a better solution and found this...
i think its great...my battery up to 2 hours and 20-ish minutes.
Anyone running Win 7 RTM and noticing lower battery life? My 6 cell can barely push 2 hours, though its missing about 30% of its capacity due to wear. Its about 18 months old with a lot of charge and discharging. I do like Win 7, the laptop is running very snappy with it.
Ive always gotten, well, not so much battery life out of my machine. However, today Ive realized it might be a problem with it, rather than how it is meant to work. Today I put a DVD (AC/DC live!), plugged an hdmi cable into my tv, and it died half way the 2 hour concert. All my laptop was doing was working as a dvd, so, I figure something must be wrong.
I'm looking for a new laptop for school/work, and so far I think the Vostro V13 seems good. What do you think?
Anyway, my only concern is that it only has four hours of battery life. However, it does come with a 7200 RPM hard drive, which seems like that would eat a lot of battery life compared to a 5400 RPM hard drive or an SSD. Well, I have an extra 80 GB SSD in my old laptop, so my questions are...
How much (if any) battery life do you think I would gain by replacing the 7200 RPM hard drive with the SSD?
Also... Would you recommend the Vostro V13, or is there another laptop that you would recommend for school?
My XPS M1530 is a beast, but it's starting to get worn out and it just isn't convenient enough to bring to classes all day. Netbooks are too small for my hands (and eyes!). I really do prefer big screens, but I suppose I must compromise for the sake of mobility/convenience, so hopefully I'll be able to get used to the 13.3" screen.
I'm having some battery life issues with my laptop, and i wanted to see if the performance of my battery is normal, or if something is wrong.
At first, my battery started draining really fast so i replaced the battery in July, and now im seeing the problems again.
Basically, I need my laptop for class, and i have microsoft word, wi-fi running, and a web browser during that time period. My brightness is set on about 4, and the battery option is on portable/laptop (note: i have tried max battery with same result)
i'm getting less than an hour of battery life..
i was wondering if there was anything i could possibly do to improve this, perhaps purchase a 9-cell battery, or if there might be something more wrong with my computer that i should get checked, i'm not sure if this is normal battery life, but i don't remember it dying that quickly before.
I just bought a Dell Studio 1555 laptop with the following customizations made
1) Vista Home Premium x64 2) 9 Cell Battery 3) 512mb ATI Mobility Radeon HD 4570 4) 4 GB Ram
Can you guys recommend me some softwares which can check my Battery performance. I am not sure if I am right on this but "THIS" software when run simulates various levels of activity on the laptop such as Casual use, High Intensity use etc etc. It runs by itself and then we can see for how long the battery has lasted. I don't think the battery meter is very accurate so can you please help me with this. Thank you. I hope I have explained myself properly
Also an unrelated question. In the future if I wanted can I get my laptop upgraded in the following parts by Official Dell people? 1) Processor 2) Hard disk 3) G card 4) Ram .....
I woul like to know how much i can get with the 9 cell battery, LED display, ssd and 8400. I am looking at a 13.3-14.1 with long battery life. Any other suggestions? I like the illuminated keyboard on the studio 1340, but it's heavier and i hate that leather part, plus the airflow problems. Lenovo u330 is nice, but have some battery problems as i saw.
It's only since I started reading these forums to try and fix my fans being on all the time that I realised my XPS's battery life was way worse than most people's on here.
I have a six cell battery and out of a full charge I get maybe 1:35. this wouldn't be so bad except, when my warranty ran out 3 months ago, I made dell replace my current six cell battery which got around 1:17 full charge.
This current battery is only 3 months old, initially it did an two hours and a half but now i'm lucky to get an hour and a half out of it.
why my computer is eating my batteries? Other people talk about battery life of 3 hours plus
