HP/Compaq :: HP DM3T Battery Life Well Short Of 10 Hours

Dec 7, 2009

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.

Dell :: M6400 Battery Life 2.5 Hours

Feb 19, 2009

Just got 2.5hrs usage on battery from my M6400 (QX9300, FX2700m, 16GB RAM, 500GB RAID 0 disk array). I was pleasantly suprised by this, as previously I've only managed 1.5hrs.

I was working on a virtual PC hosted by the M6400 - developing C++ code - (connected via RDP), included lots of builds and test runs etc to the (also hosted as a VPC on the M6400) sql server.

Lenovo P/Y/Z Series :: Z500 - Battery Life Below 2 Hours

Apr 1, 2013

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.
 
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.

HP/Compaq :: DV2 Undervolting: Get At Least 25% More Battery Life

May 6, 2009

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, its 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 its 100% safe), since the benefits for dv2 and AMDs neo are so dramatic!...........

HP/Compaq :: Battery Life (HP8730)

Jan 25, 2009

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.)

How much time do you get with your 8530w?

how do you like the 1900x1200 screen?

HP/Compaq :: Dedicated Video Bad For Battery Life- DV7

Mar 23, 2010

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.

HP/Compaq :: New DV4T-1147CL- Battery Life

Jan 14, 2009

Grabbed a display model of the DV4T-1147CL from Sams Club yesterday for 599.99 + tx.

Configured as:

14.1 high def brightview infinity display
4gb
64bit vista home sp1
320gb drive
dvd+/-R drive
6-cell battery
intel 5100 wifi wireless N/bluetooth
T5800
Geforce 9200M GS w/ 512 ddr2

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?

HP/Compaq :: Battery Life Worse After Format

Apr 29, 2009

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!

HP/Compaq :: New Envy 15How To Increase Battery Life

May 31, 2010

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...

HP/Compaq :: Vastly Different Battery Life On 13 & 14" Models

Aug 14, 2009

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?

HP/Compaq :: HP Envy I5: Heat, Graphics Switching And Battery Life

Feb 21, 2010

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?

Acer :: 4810T + Windows 7 = 4 Hours Battery

Jul 20, 2009

I just purchased a 4810T laptop, formatted it, and loaded windows 7. Now on power saving Mode it says i only have 4 hours of battery left.. what happened to the selling point of 8 hours?

I'm thinking it might be because I don't have the empowering technology and power smart applications installed, but i can't install it anyway as it doesnt work on windows 7. So whats the problem here? my laptop, windows 7, or acer software?

Acer Switch 10 :: Battery Icon Keeps Saying 100% Even After Several Hours Of Use?

My battery icon keeps on displaying that my battery is not depleting, which is weird since I've been using my laptop for several hours now and it is still at 100%. When I plug in, it registers that it is plugged in but says fully charged. Not sure if this is a magical always - full battery - or a problem?

Dell :: Superclean Install9 Hours On A 6 Cell Battery

Mar 20, 2009

UPDATE: Cheat sheet to the superclean install posted
[url]

I am currently experimenting on seeing how far beyond the manufacturer's specifications I can take my machine. I'm keeping track of the steps I've taken, and will update this post when I feel I've reached the limits of what this machine is capable of doing, along with exact steps on how to reproduce my setup. Here's what I've currently achieved:

- A maximum of 9 hours of battery life on a 6 cell battery using 6.5 watts
- 6.5 hours of typical battery life while browsing using 8.5 watts
- No audio stuttering/crackling and perfectly green DPC latency
- Super quiet operation with no fan noise (fan stays off and doesn't spin)
- CPU temperatures around 33 degrees, rest of computer around 40 celcius
- Roughly 25 seconds to reboot to a working desktop (not just login screen)
- Only about 0.37 gigs of ram being used when idle

Machine specs are Dell Latitude E6500, Intel P8400 CPU, Intel X4500MHD Graphics, 1440x900 WXGA+ LED Screen, Corsair 128 Gigs SSD, 1.5 Gigs RAM, Dell 1397 Wireless, Dell 370 Bluetooth, DVD RW Drive, Webcam, Backlit Keyboard, 6 Cell Battery, Windows 7 Beta Build 7000.

Apple :: New To OS X - Battery Life

Jun 6, 2009

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%?

Apple :: Anybody Else Being OCD About Their Battery Life

Sep 24, 2009

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...

Dell :: XPS Keyboard And Battery Life

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 its 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?

Dell :: Studio XPS 13 Battery Life

Apr 16, 2009

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?
