Dell :: Seperate Power Modes For Battery And Plugged-in
Jan 4, 2010
I own an Inspiron 1545 and would like to set-up two profiles, one for use when on battery and one for use when plugged in. Basically,
I want my laptop to run at maximum performance/brighter screen when plugged into the wall and have it run in a power-saving mode when running off the battery.
The Windows7 power options don't seem to be able to differentiate between plugged-in and battery operation. Is there perhaps a program which I can install to do this or is it just not possible??
Working on a dell Inspiron b130 laptop. The power is plugged in, and battery is in. The power will not turn on at all, no fan or CPU. The main power light comes on when button is pressed for a moment then goes off. The battery light flashes slowly. The power cord adapter has a light on it and that says its working. I have tried taking the battery out and that does nothing.
I had assumed since its an older laptop that maybe the power was so drained that it needed it to be charged a little to have enough power to turn on. But it's been awhile an nothing yet. Is it trashed? We do have another hard drive around to try would that matter at all?
My battery on my acer draws power at times when my laptop is plugged in it will work ok then the on and off button will start to blink It will go into hibernation when plugged in when the battery gets to low....
Our Studio 1749 will retain a solid connection when the power adapter is plugged into the power board along the side of my laptop. I am unsure if the pins residing in the power board are pushed toward each other so as to not retain connection when the adpater in plugged into the laptop.
Can I upgrade my dvd Rom to the blu-ray/dvd/Rw slot and I should have done it before ordering the the laptop? So I guess my question is: Is the blu-ray slot something I can order as an upgrade?
I bought one Alienware M14 x last month. However, I found it won't boot when the power adapter is plugged in. If I unplugged the power cord, then press the power button, it will start normally.
dell xps m1210-worked fine forever-few weeks ago intermittent failure to show charging when plugged in-jiggled-twisted-would charge. last week same issue-no amount of jiggling would produce charge indicator. took to fairly well rated shop after research re installation of new ac jack-after done no difference. they find power enters at jack and then they lose it on MB somewhere they cant seem to reach to test.
I own a Acer Aspire 8930g which I bought at the end of November 08.
Ive been having power problems, Id be playing a game or just browsing the web, and the machine just switches off. Upon booting up again and logging into windows I notice the battery is completely flat, and is charging at 1%
The laptop is ALWAYS plugged in.
It seems to run down the battery if the computer is put into sleep mode, even though the power is plugged in, and also, I think, cant be 100% but seems to drain the battery even when fully shut down with the power plugged in.
Strrange problems and is really annoying as you would imagine if your in the middle of a good game or halfway through a good movie.
Do you leave your battery in while the laptop is being used with the AC adatper? Does this affect the battery life in any way? Definitely makes it lighter if its on your lap!
So last night my laptop was running fine on battery power, but then it was running low, so I plugged in the power cord. Nothing happened. Since the adapter at the laptop end was falling apart and duct-taped anyways, I figured it was just conking out, but then I saw the indicator light on the power brick was off.
With some experimentation, I found that if I moved it to a different outlet, the light would come back on, but if I plugged it into my laptop, the light would die, and I would have to again move it to a different outlet (the same one as first would work fine) to get the indicator light back on. It works in other Dell laptops. Other adapters do the exact same thing.
So I'm guessing there's a problem with my laptop wiring that's causing a short or something. (Apologies for my shallow electrical knowledge.) But it was working last night on battery power. Until the battery died completely this morning, it would power up. So it's not an electrical problem that kills the laptop.
I have a refurbished T410 that words fine and charges the battery when plugged in. When I remove the power ca ble, it dies immediately. The battery shows fully charged, but will not turn on unless the power cable is plugged in.
Apparently Mac OS X has three hibernation modes (as outlined below from an official Apple document): a. Always save the RAM content to HD and hibernate (this is the default), b. Dont save RAM content to HD (I think this is the "regular sleep" and risks losing data if power is interrupted), and c. Save RAM content to HD and hibernate when the battery power is at a critical level.
I am planning to change the default scenario (point (a) above) to the (c) to avoid writing RAM content to HD every time the lid is closed. Has anyone changed the hibernation modes before? If so, has there been any problems with battery life, data loss, etc etc?

Can someone help me figure out why my battery drains while my laptop is turned off and not plugged in? It started just a few days ago and I can't figure out why it would do this
I have spent two days reading forums & trying to follow suggestions. I have gotten a new battery (prior to finding out it might not be the problem), reconnected the power cord/adapter and did a bios update. Bios still says adapter is "unknown". Battery (new one) reads at 41% (& holding), the old one at 37%. Another way to charge the battery?
My year old XPS 13 Ultrabook's battery is not charging when plugged in. I measured the voltage of the power adaptor at the plug (the end that connects to the Ultrabook) and the voltage level seem fine at 19.4V
However when I plug and unplug the power when the Ultrabook is off, the LED turns on and off accordingly.
My Ultrabook is L321x, running Windows 7, and has BIOS A7 installed.
how to fix dell inspiron 15r battery plugged in not charging problem? i bought the laptop from dell in november last year and the charger that came with the product got wet and stop working i went to a computer store here and bought a 65w charger and after about a month using it start saying that its not the same exact charger that came with the laptop but its an original dell 65w charger it even say i should get a 65w or higher and it still dont work it works when it feels like
I just had a battery replacement for my Dell XPS 15z.. Prior to the installation of the new battery, the machine could only work with the AC adapter plugged in, raising the suspicion that the battery was defective. However, now that a new battery has been installed, the battery does not charge even whiles the AC adapter is stilled plugged in.
My battery light is flashing red and the battery icon says that my charger is plugged in but not charging. So when I unplug my laptop it automatically dies. It's been like this for a couple of days and i've tried to just see if it'll go away but nothings happening.
When I pull the power cord to switch to battery power while in Windows my lcd goes to black. The only way I get my video back is a hard reset and reboot. Later on I tried this and everything was back to normal. Why is this happening? Is this some weird standby?
I had this plugged in but no charging issue and I called, they said it was the MOBO or the AC. So the guy came today and put in a new MOBO and used a new AC, but it still won't charge.
So he called Dell and they said it had to be the battery (even though we don't get the light 1/3/5 indication on the battery meter), and that since I was out of the 1 year battery warranty I would have to pay.
Well here is the thing, I have a freaking 4 year warranty on this thing, and it is barely over a year old and the battery already failed? WTH is up with that? Also, the guy said my battery warranty expired in March, but I didn't even place the order until June and I didn't get the computer until July 18 or even later. And they won't approve my battery replacement, they said if I called before the end of July (like 2 days earlier) I would be able to. This is ridiculous.
I had bought a new battery since my old one was dead. I charged it up and was using it for a couple days. After that, I got the "plugged in, not charging" message. I thought it was the battery, so I got a tested replacement battery. I still got the message, so I did that uninstall battery device manager solution, and didn't work. I also updated BIOS to A14, bought a new A/C adapter, and still no luck. The A/C adapters say "unknown" in BIOS though both A/C adapters are Dell. Here is a picture of the laptop jack. [URL] .....
About 1 Year ago i Bought a new DELL 5521 it was working fine, but like 2 days ago i was playing games in battery mod, it suddenly pop low battery 6% or maybe 10% so i force shutted down, and like not its charging up-to 60% or 65% and after this it says Plugged in not charging... i don't know why its not going above 65% percent. I Tried SEVERAL THINGS PEOPLE SAID, in Google in Forums Nothing Worked & it Also Sometimes Plug and Unplug By it Self Like for 2 Seconds it Unplug it Self, and then plug again and i dont know why....
My z500 cannot boot up without power cable plugged in. Usually,a few seconds after I saw the lenovo logo,the system will suddenly shut down just like the battery was removed.however,if I connect powercable to the laptop and power on,everything is fine,I can enter windows 8,or ubuntu,after I enter OS,I can disconnect the power cable without any problems.the battery is healthy and can last for more than 2 hours.
So far I tried the following methods: 1.update BIOS 2.update battery firmware 3.reset BIOS none of them worked for me....
