I am using a HP Pavilion DV4 series laptop for the past 18 months. Till now, it has worked fine. Nowadays when i disconnect the main power adapter once the laptop battery has charged to 100%, the battery indicator shows immediately that only 72% charge available..If i plug the adapter again, it again shows that 100% fully charged..
View 4 RepliesBIOS reads the battery health as "Performing normally" and the charge at 100%.
but when I unplug the computer, it doesn't go to battery power, it just shuts off. Like there isn't a battery there.
Bought the battery off ebay, it's not a genuine Dell battery, but it worked great.
Whenever I unplug my laptop from external power, the screen considerably dims and the taskbar turns white over it's usual blueish black. I've gone into the power settings and changed them so that brightness is 100% when unplugged, but to no avail. According to my computer it's at maximum brightness when unplugged but it's obviously not. Trying to increase the brightness by the sun key or pressing Fn up doesn't work either. Tried to go into BIOS via F2 but couldn't find a video or brightness option.
View 2 Replies View Relatedmy Inspiron 17R no longer recognizes when it is unplugged from the AC adapter. This means that when you check the power icon it always claims to be connected, even if it's not, and that the charge meter basically can't be trusted (it'll say it's fully charged when it's not). It also means that it fails to adhere to its power plans because it never goes into battery-only mode. I have contacted my local Dell tech support, but after checking my bios and seeing that my computer recognizes the AC adapter, they didn't know what to do. how to get my laptop to properly recognize when it is and isn't plugged into the power supply?

When unplugged the laptop suddenly shuts down even tough the battery shows 29% still remaining.
I receive no notification from Windows or anything, it just shut downs like when the battery reaches 0%.
Then in order to start it again, I need to plug it in.
I previously didn't have any battery problems and running the HP Assistant informs me that the battery is ok and it doesn't need replacements. Basically the laptop is dead at 28%-29% battery life.
I have an Aspire M5-581T. In March of 2014, the battery suddenly stopped working. It would not charge, the unit would not boot from the battery, and if I unplugged the computer from the AC outlet it shut down completely.

I recently purchased a dv4-1275mx special edition, and would like to calibrate the battery. The battery is suppose to last up to 6 hours (I'm expecting about 4-4.5). Does it screw up the calibration if I am using it while letting the battery run down. I have the screen turn off disabled and the sleep disabled, but I am using a screen saver.
View 3 Replies View RelatedI understand you can run off the adapter, But with the battery installed , i cannnot. If i plug adapter in like Iam charging it (not turning power on ) the light in front lights up just briefly then nothing. I also can't power laptop on. If i run the adapter with no battery in laptop everything works fine. What causes that? Just a bad battery? motherboard is new and so is the cord.

I have a HP Compaq 2230S business laptop, but this question could be put to any HP laptop. The fan is constantly running when the laptop is plugged into the power outlet, but as soon as I pull the plug to run on battery power the fan powers down and stops. I re-plug the laptop back in and the fan kicks up again.
This is not good as I almost burned myself when I picked up the laptop after an hour sitting on the table on battery power. The hard drive is right beside the processor, so the laptop gets really hot.
Vista x64 Ultimate is what I'm using at the moment and my power scheme calls for 1% minimum and 100% maximum CPU on battery power.
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.

HP tech is trying to help my by telling me to test the battery life and resetting the bios, however this laptop is only 2 months old and I had the problem since the begining.
Its a dv3 Pavilion.
I have an HP DV6560 and I have a problem with my battery. She discharge when the laptop is shutdown (no stanby).
All drivers are installed and updated.. bios, chipset, etc..
For information when the laptop is shutdown no alimentation is activ, I have tryed with un mouse USB.
Juste again, the battery discharge only when is plugged in the laptop. But when is plugged off, the battery no discharging.
Maybe is the remote control option who discharge ma battery when my laptop is shutdown, but I don't disabled this option in the BIOS..
My mother was having some trouble with her laptop, and I was wondering if you guys had an idea of what the problem could be. Basically, it won't turn on, even with the battery plugged into the wall. It is completely unresponsive. The last time she used it was last night, and she said that when she was done, she left it on with the screen down and the battery plugged in.
View 7 Replies View RelatedLast night I was using my E1705 running on battery when the thing just suddenly zapped off. I had recently glanced at the battery meter which was 75% full. I pressed the button on the actual battery which shows 3 of 5 lights on the charge meter.
The battery itself is only 1 month old and has been performing flawlessly. I just thought it was something random so I plugged the machine in and it started up.
I didn't think anything else of it till today when I went to move my laptop, removed the power cord, and the laptop turned off. I checked the physical battery meter which still reads 3 of 5 lights .....
I am leaving town for 6 weeks and giving my desktop to a friend to hold onto while I am gone from the dorms. I don't trust the dorms with this computer. She is going to just be keeping the desktop in her room packed up in the box. Is it safe to do this? Will the internal battery die over those 6 weeks and not being plugged in? I just want to make sure that it's kept safely in every sense possible.

I'm having ALOT of drop-off issues from my wireless network when my system is unplugged. Sounds really odd, and my system is either set to balanced or high performance when unplugged, but there it is.
When plugged in, I have yet to notice a dropoff. So I'm assuming they are connected.
It'll typically drop for about 2-5 minutes and then reconnect.

Does this mean my battery is faulty and needs to be replaced?
My XPS 17 laptop sometimes beeps continuously with the sound of something being unplugged or plugged into the USB ports, but this happens when nothing is connected. Occasionally, a message comes up saying that USB device is not recognised - which makes least sense when nothing is plugged in. What is causing this - perhaps a setting on the computer - or perhaps a solution?

View 5 Replies View RelatedI've recently bought an Acer Aspire 6930G and am overall very pleased with it.
However, in the few weeks since i've bought it there has been one concern I have had.
Whenever the laptop is unplugged from the mains, it starts to make a faint buzzing sound. The sound seems to come from the 'tube' near the subwoofer on the back (where the power socket is on one side, and the Kensington Lock is on the other side). The buzzing also only seems to be coming from the right side of the laptop above the number pad.
What is also strange is that i am able to stop the buzzing by tipping the laptop sideways or moving the screen. This seems to indicate that something might be vibrating, but again only when the power cord is unplugged?
Like i say, i don't think its enough to take the laptop back (unless somebody tells me differently), but i am concerned enough to ask on here if anyone with the same or similar laptop has any ideas as to why this might be happening.
I have a problem with my Lenovo. The problem is that whenever I plug or unplug my pc adapter, the screen goes black for a second or so. I didnt experience this problem before, it started to occur a week or 2 ago.URL....
View 1 Replies View RelatedOur company recently purchased two Dell Inspiron 3721 Laptops (Windows 7) with two SuperSpeed USB 3.0 Docking Stations. Both laptops are fine and can connect to the network, but both network adapter on the docking stations don't seem to work on either computer. The lights on the network adapters for both docking stations don't light up and the adapter settings on the laptops show the LAN connections as "Network cable unplugged." The cables work, as we tested them on the laptops themselves. We've also tried uninstalling and re-installing the drivers with no success.
