Ive had my Acer 3680 since 4/07. I bought it brand new.
I keep it on the charger 85% of the time, and when its not on a/c power, I switch over to "power save" mode.
I was surprised about a month or two ago when my battery icon had a red "X" through it.
It would be there whether it was charging or on battery power. When I switched to battery power, it would be at 100%, but then be down to 7% in like 2 minutes and shut off. I was able to get a new battery on ebay and now I have no problems. I cant help but wonder though, how long are people reporting with their 3680's?
We have a Dell laptop at work that we've had for 5 years with the original battery. Im not trying to diss Acer or anything. It could be I just got a fluke battery. I'd like to see how long your 3680 battery lasted before you had to replace it?
I just got the 3G version of the Netbook with the 3 cell battery. I'm only getting a bit over 2 hour of battery life with 3G off, my wireless connection on, the screen brightness about half way, and the only program open is Firefox. For example, right now I have 90% capacity and it's showing 1:55. Is this the normal battery life. I know the specs say up to 3 hours, but I never believe in those, and I just want to make sure mine is about right.
I was thinking of getting the 6 cell battery, but I don't want to make the netbook any bulkier than it is (I'll be carrying it back and forth in my work commute).
i have an Acer 5920g, When i first purchased it (2 ish years ago) i would get around 1.5 hours use out of it after a full charge and on high performance. Now im gettin 45mins - half of what i used to get?
My mom has an Extensa 4620 which couldn't have been already years old, but seems like its battery is giving way.. She told me she keeps noticing that instead of almost 2 hours battery life, now she only gets 30 minutes from it, in High Performance. I've installed RMClock on it not too long ago, but I'm sure it isn't because of that..batteries don't fade that fast, now do they? Can we like send it back to Acer or something since it already underperforms for its age?
I"m looking at the comparisons between the Acer 1810 T and TZ models. The primary differences are in processor and cache sizes. Could anybody guesstimate whether there would be differences in battery life on the two models, ie the SU4100 and the SU7300?
Battery life is probably more important to me than slight performance differences.
The Acer Timeline 3810tz is advertised to get 8+ hours of battery life. Those who have tested get about that amount while browsing the web and doing simple task, and this model contains a single core processor. I read somewhere that the Acer 3810 model with a dual core processor SU4100 get half that battery life and only goes about 4 hours.
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%?
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...
The internal IDE port got fried and cannot be recognized by the laptop so I came up with the bright idea of installing an OS on a USB drive and booting from that.
XP appears to be the only OS that will install onto an external drive. But, when booting with XP, I get a BSOD..
VISTA won't install to a USB drive so I installed VISTA on the external drive using a workstation, but then when I tried to boot up with the laptop, it got the solid B/W bar at the bottom and just sat there.
Is there any option to boot an ACER 3680 with an xternal drive?? Or is this laptop now useless?
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%
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 was just wondering if anyone experienced a battery increase after down-grading their Vaio Z from Vista/Win7 to XP? If so, by how much?
I'm currently holding a Z710dd (canadian vaio) with a standard battery with windows 7 installed. I previously had a netbook that lost a good hour and half from Windows XP to Windows 7. Even after disabling a lot of the windows aero mumbo-jumbo and themes
I recently purchased a Vaio VGN-SR390 with the "9 hour" battery. I understand you never get that. But what I think is odd, is that no matter what settings I change, including WiFi on/off, it *always* says 3:55 to 4:00remaining with 100% charge. (I haven't actually timed it on the clock, though.)
1) Is this what other SR owners are getting? about 4 hours...no matter what
2) How do I make sure bluetooth is off (haven't been able to figure that one out)
3) Should I see the battery life increase with reduced display brightness, Wifi off, etc?
