My Envy has the i7-720QM processor. I noticed significant reduced performance when running on battery.
RealTemp, Sandra, i7Turbo, Intel turbo boost monitor, cpuid, etc.. all report the multiplier at 7 (~930MHz), and won't move from there no matter what I do on the machine.
The multiplier seems locked/fixed at 7 regardless of load. As soon as it is unplugged it dives to 7.
I've changed the power plan to high performance and set min/max power management to 100%. This made no difference.
Is the BIOS forcing this? I believe 7 is the low frequency multiplier but shouldn't this kick in only is there is no activity (to save power?). If I am doing work, I expect the processor to at least run at the minimum frequency specified.
This behavior has been confirmed now by other members of the forum. Previos BIOS releases (F.05 and F.06) have been tested and showed the same issue.
I attached two screenshots, one the system running on power, and the other one on battery. Both running prime95 small FFTs.
I updated the bios which fixed other issues. I updated the drivers and did all the win7 updates to rule any of that out. When teh laptop gets down to 18% it just powers off instantly. It does not go through a normal shutdown process or hibernate. I can power it back on and it shows 18% battery left. Is the battery going bad? I dont think this machine is barely a year old yet. I have no problems on wall power. Could it be a Win7 power setting? Just surprised win7 would slam the power off like that.
I just received my MBP 13" yesterday. So far I love it. However, I noticed an issue. Last when I put my MBP to sleep, it had about 30% battery left. However, when I woke up this morning and opened my MBP, the battery went down to 13%.
When I put the laptop to sleep, I had a pdf file open along with itunes (paused). I have never used Mac OS, so maybe I not doing something correct. Also, I noticed when I open the lid (after I put the notebook to sleep) it just goes directly back to the desktop as opposed to on windows it prompts to the login screen when waking it up from sleep mode.
I finally fixed all my problems (kinda) I have sound, wireless card, can go stadby hibernate, ethernet device works etc etc, Don't know how I did it because I went to so many different sites and google it thousand times!!!
I've noticed that sometimes you can't get the right drivers from dell even with the service tag number, I got some drivers from dell, but not from my specific model drivers download page!
The only problem I have now is that my hotkey: fn+esc don't work, it doesn't put my computer into standby like it should, the other hotkeys work just fine, Anyone know why? I also would like to get an older version of quickset because the new version that I got now I don't like it, its 7.1.8, I've been looking for the version that came with my computer from the factory but I don't know what version is! I liked that one better.
i have a mini 1014tu that is mini 1000 series... every time when i plug power line the screen become very bright.. every time i change the brightness... that come back to most bright after plugin or out...... how to fixed? i use windows xp sp2
I've been using a Dell inspiron 1545 from about 3 years now and exactly after 2 years of my buy, the battery failed and it started showing me to replace the battery and always notified me about contacting dell for a new battery.
I didn't take this of much concern so i just ignored the message and kept on using my battery with my adapter plugged in. After 4-5 months of such usage, My battery completely failed and doesn't even offer me even a minute of backup, when i remove the power socket. Then i realized the importance of a new battery and then bought a new battery from Dell.
Its the same battery with the same specs and also the same family type. After i removed my defected battery, I replaced my new bought Dell battery and realized that my battery is working fine. its charging well but at some time, it says "Plugged in, But not charging" Which is rare for any new battery, which is bought brand new.
This is how it looks now after i remove the AC adapter plug and when i depend on the battery backup. it is providing me a backup, but I see a yellow exclamatory mark beside it. Which I think should not be present. it also says "Low battery" when there's already 99% of battery left!
I've also followed some online steps
1) updated by BIOS to the latest 2) Followed some other steps like uninstalling the battery ACI in the device manager and etc...
I'm using a PA-12 family adapter, which is also a replaced one.
the battery time remaining indicator on some of the Vaio models (my FZ190 for example). This was due to the fact that the supplied apps from Sony didn't support showing the amount of time remaining.
I just came across a free app (actually a Vista toolbar) that does its own estimate of battery time remaining, based on its monitoring of the power dropping as the battery is used. It works GREAT on my FZ190 and should work on ANY machine that does not natively support this feature.
I did a search on here and and google and I came to the conclusion that if you dont know the specs of the computer you can't "accurately" guess the life of the battery so I'm hoping you guys can give me an estimate with my computer specs.
I'll post the things I think would matter most with the battery life.
Specs: Dell XPS M1330 2.2 ghz core2duo 8400gs LED screen wireless-n 160 gb hdd (dont know speed, im sure you guys do with this size)
My laptop is Dell ultrabook XPS 13. I've been used it for about 6 months. I don't know when it started to be like this but I've just noticed recently that the battery shown on desktop is never full charged even when it's plugged in for long hours. Last week it's at 41-42% at maximum but now it never reached more than 39% and it seems to be less and less even though I keep it plugged in every time I use it. I'm worried there's something wrong with battery but it said my battery is still fine, but obviously it's not fine.
I just bought this and when i first got it it said 5 to 6 hrs remaining but now it shows 2 or 3 hrs after a full charge (it says up to 7 hrs on website). I have updated the BIOS and drivers which worked for a while but its back to 2-3 hrs again. In the BIOS it says the battery is running normally.
I just recently picked up my new DV7, wiped the drive and re-installed Vista Ultimate x64. The machine itself runs great, but after installing all the drivers and the most recent bios, I hit a strange snag- I have my right channel speaker, works fine. But my left channel isn't coming out the left speaker, but out through the subwoofer. I've tried uninstalling the IDT codec and letting Vista use it's own driver, same deal. Re-installed IDT, same deal. I get no sound at all through the left speaker, and Vista only recognizes me as having 2 speakers.
So a few days ago, my computer just all of a sudden began making a strange "grinding/crunching" sound which seems to be coming from the top left side of the computer. The sound is very clear especially from the back left corner vent. The noise seems to come and go but still has me very worried. I've read this noise may indicate a dieing hard drive, however tests came by negative and also the hard drive for this notebook is in the middle, not toward the top left. Anyway, I recorded the sound twice and was wondering if you could take a look and tell me what you guys think (you might wanna turn your volume up). I have an HP Dv7t
where my laptop would shutdown randomly and give me a real time clock error. I googled around and found that replacing the cmos battery would fix the problem. I tried it out but still i am getting this problem.
I have a dell xps 15z laptop and I have replaced the battery because it was not giving any backup. Now i plugged new battery but the battery icon says"0% available, (plugged in, not charging)". Also an indicator is blinking (four times orange and one time white) below the laptop screen (the hinge where screen is attached to the base of laptop).
