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.

I know the usual drill, disable bluetooth, reduce brightness and etc.. but since i bought my mac (October) my battery life have decreased from 4:30 hours to about over 3 hours. Does anyone have anytips? Use black wallpapers? Use safari instead of firefox? We could make sticky thread for reference for future mac owners. i am using safari right now, and it seems to be consuming more energy than FF

Looking at this model right now, I see the battery option has up to 8 hrs and 42 min with the 9-cell. Is this true?
Are Dell Studios really superior on battery life, or is this over-exaggerated?

I have an XPS m1330 (T7500, 3 GB RAM, 8400M GS GPU) and had a bad 6-cell battery that wasn't holding charge.
Dell sent me a replacement, but they've sent me a 9-cell which I don't want b/c it's heavy, adds bulk and most importantly, the angle on the laptop REALLY hurts my wrists... but apparently they won't send out 6-cells as replacements anymore, just 9-cells.
I'm wondering if there's anything I can tell them to get them to send me a 6-cell without having to put my 9-cell on ebay or something .....

I'm looking to get the Studio 1555 and the only thing I'm not sure on right now is which battery to get.
Is it true that the 9 cell sticks out the bottom a little bit? I would just go for the 9 cell, but I use my current laptop on my lap a lot and I'm worried that if the battery sticks out the bottom it would be uncomfortable since the laptop would be resting on two points rather than the entire bottom

how do I check how many cells my battery has? Its either 4 or 6, since it doesn't have the external prop behind it.

I have a Dell Inspiron 6000 for about 4 years almost. I have 512MB but am going to buy the 2GB ram from newegg because it is very slow.
I am also formating my laptop as well as my desktop. Most of the time i use my desktop but for my laptop i bought a charger that was CHEAP and i think it messed up my battery life a bit.
I just purchased a new charger from Dell and will throw away the bad charger i have.
My battery life in my 6000 is about 40 minutes. It used to be 2 hours and 30 minutes when i first got it. A few months ago it was actually 1 hour and 20 minutes. My neighbor has a e1505 and his battery lasts like 5 minutes now so all he does is use his charger.
I see on Ebay from reputable sellers that the 6 and 9 cell battery price is pretty close. 6 Cell is about 44 dollars and 9 Cell is about 48 dollars.
6 Cell one

i am having a hard time deciding my configuration for a inspiron 13"
i noticed that the Refurbished laptop have a Great price $609, 2.0 intel core 2 duo,4gb,320gb,6cell,Dell 1395 802.11G Wireless Mini Card.
For that price it seems to good to be truth, but i have no experience with refurbished laptop.
What is causing me confusion is, if i should go for a new laptop that has ,2.0ghz(same cpu), 3gb,250gb,intel next gen wireless N, 9 cell battery
for $779, all because the $10 for the wireless and 70$ for the battery
and it has a 195$ discount already of the original price.

I have an HP Pavilion dv6000. When I purchased the laptop, I chose a 12 cell battery, and it has a sticker on it that states: Replace with 451864-001. My battery went bad, and I purchased a replacement at the HP Parts Store online. I specifically chose a 12 cell replacement, which brought up the same part number, i.e., 451864-001. However, when it came in the mail today, the battery looks like a 6 cell, as it's about 1/3 the size of the old 12 cell, despite my purchase receipt which states that I ordered a 12 cell and the packing slip which also states that HP shipped a 12 cell. The model number of the old battery is HSTNN-DB32, and the model number of the new battery is HSTNN-DB46. Unless they were able to shrink the 12 cell to make it resemble a 6 cell, I'm pretty sure I received a 6 cell, despite the notations in the purchase order and packing slip.
This is a long way of asking, is there a tool that I can install that will tell me how many cells are contained in the battery? The battery, itself, does not state how many cells it contains. If it is a 6 cell, as I suspect, HP will be getting it back.

Couple of questions:
1. Does the 9 cell PROTUDE out the back and is it thicker than the normal 6 cell?
Would love to see a photo comparing both if possible.
2. Practically, in terms of percentage, how much more run time? 50%? 60%?
3. How much more weight?

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.

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?

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?

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 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.

I've just purhased the above for my son who is in hospital having chemo at present. Very disappointed with the battery that is only lasting for approx 1.5 hours. I have it set to a balanced use and so far the laptop has only been used for surfing, etc.

I ordered my SXPS on 7/17..
it hasn't shipped yet, so I can probably still take advantage of the 9 cell free upgrade.
I am concerned though, about the size it adds to the laptop - i don't like the bulge much. But I just read elsewhere that the 9 cell fixes some heat issues with the laptop..is this true? And is the difference significant (heat-wise)? I'm reconsidering now..

how long the 85 WHr Lithium Ion 9-cell battery lasts while surfing the web/word processing and how much it sticks out of the computer? I am probably buying one and I would really like to know.

I recently ordered a Dell Studio XPS 1645. By default it came with the 9 cell battery. I also ordered an additional 6 cell battery for it.
Is it ok to use the 6 cell battery with this laptop? Obviously the battery won't last as long, but will the laptop run ok? I'm asking because my laptop is going to be plugged in on my desk most of the time and the 6 cell keeps the laptop flat.

Just in case anyone wants it, you can get the 9-cell extended battery for the Studio XPS 16 for $59.99 on sale. It's on sale for $79.99 right now and if you apply this additional 25% off coupon it will be only $59.99. Great Deal!

Hoping for some insight.
I have a 90w Dell charger that came with my studio XPS 13 (6 cell).
If I was to use this charger on a 3 cell Dell Inspiron Mini 12, can this seriously damage the 3-cell battery, or are the chargers smart enough to know what type of battery they're charging?

I know there currently is a 6-cell and a 9-cell for the M4400.
However I also remember reading that Dell has a 12-cell out for some notebooks in the new E-series.
Does anyone know whether there is going to be a 12-cell battery that can be used with the M4400?

I was just about to pull the trigger on a m1530 via dell.com (US) but found I am no longer able to configure it with a 9-cell battery.
I know I can easily buy the battery separately - but I was wondering what the likely reasons for this option disappearing are - could this mean they have stopped making 9-cells (maybe EOL for m1530)?
Wouldn't they normally just delay the ship date if the component was due to come back later?
Side note: as an alternative, I'm considering the SXPS 16 - does anyone have both a SXPS 16 and m1530 and can comment on the size/weight difference?
