Dell Inspiron 17R :: Laptop Does Not Recognize When It Is Unplugged From Power
Oct 29, 2014
my 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?
My laptop Dell Inspiron 5520 has not been detecting the battery.On start up it gives a error message "your battery has experienced a permanent failure and needs to be replaced.The system will power down if AC is unplugged".
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.
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..
I have a 1 year old HP Probook 4540s that recently has the following problem.
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.
My Dell Inspiron 5423 laptop does not power on normally; when I press the power button, nothing happens (no lights, no sound). As a result, I have to press the Embedded Controller reset button at the bottom of my laptop for the power button to work. I don't want to have to undergo this procedure every time I turn on my laptop.
I recently got a new battery for my Inspiron 15R, N5010, charged it but didn't use it for a while. When I decided to do some work on it, now the Power botton and Battery light is flashing white. Try the troubleshooting of removing the battery, power cord and hold the power botton down for 10 seconds, it's still flashing. Not sure what to do next.
Our 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.
This is a late 2008 build Dell Inspiron 1545, sold retail in December 2010.
Pentium dual core T4500, 2.3 GHz
Has been in irregular use as a spare machine, mains adapter only, battery removed. My house was struck by lightning over a year ago and adapter damaged. Replaced adapter and no further issue until now.
Laptop would not power up, no light. Tested adapter and tried another 2 adapters - still no power up. Replaced original adapter and plugged in depleted battery - powered up but had to press F1. Powered up with no issue with good battery. Once powered up the laptop seems to be charging battery OK. Guessed this was a power board issue but no change when replacement fitted.
I have just received this laptop. I followed the instructions out of the box, installing the battery, then connecting the power. The battery started charging that first time, but after that, any time I tried reconnecting the A/C power supply, the laptop would not recognize the adapter and I am not able to charge my battery.
I have tried the following steps:
1. Shutting down the computer, removing the battery, and starting the computer from the A/C power supply. The computer will not recognize the A/C power supply to turn on the computer.
2. Updating all the power management drivers. Everything was already installed properly.
3. Using the Lenovo Energy Management battery gauge. I must have the A/C power supply plugged in to use it, but the computer still won't recognize it.
4. Held down the power button for 30-40 seconds then reset the BIOS to default settings. No change
5. Tested my outlets and connections between my AC adapter cords. Everything is working properly.
There is one way that I can get the computer to recognize the AC adapter, and that involves all of these steps shown below, but when I unplug the AC adapter I am right back to the beginning, and I have to redo the whole process. I have just received this laptop and I am quite sure that you shouldn't have to go through this process every time you want to recharge the battery, or use your computer while only powered by the AC adapter.
Steps I have to take to recharge my battery:
A. Disconnect the A/C power supply. B. Shut down the computer. C. Remove the battery D. Connect the A/C power supply E. Start the computer. F. Uninstall all battery drivers that are labeled Microsoft ACPI Compliant Control Method Battery (which come back every time). G. Shut the computer down. H. Disconnect the A/C power supply. I. Insert the battery. J. Insert the A/C power supply. K. Start the computer.
That is the ONLY way I have gotten my computer to recognize the A/C power supply. I know the power supply is functional, but why I have to go through all of those steps for the laptop to recognize it.
Recently, it can't power on. Assuming that it was a static-flea problem, having happened before, I did the "remove the battery & AC power, holding down the power button for 30 secs" solution countless of times. Yet, to my dismay, it still couldn't power on.
I did notice, however, that each time the battery and the ac power were in and the socket power on, the battery indicator and the ac power cord were both lit. With this, I am certain that the AC power cord is working, and probably the battery is as well. I have also tried directly relaying the ac power to the laptop without the battery attached but failed.
Inspiron 17R N7110 has no power, I was watching movie and the laptop just froze, after waiting a few minutes I performed a hard power reset, machine was restarting, abruptly shut off and has been dead since.
Tried the power reset by removing the battery and holding the power button for the static discharge ... and so on. No luck. Machine has no lights on front, it is completely dead, battery was 100% charged. Tried two charger cables, both have green lights till I plug them into the machine then green lamps die.
I think it would be the DC power connector or the motherboard... or something else that I have not thought of yet.
I have a Dell Inspirion 1526 that when I turn on the laptop, the blue power light comes on and the lights all come on but the screen is black. I here my laptop running but it looks like my screen just stopped working. I wasnt sure what it was so I bought a new battery to see if that was the problem and the screen still does not come on. I had this laptop for about 3 years and thought it was the battery or charger and its not.
Laptop is on and plugged into the docking station which is "powered". Connection to monitor / keyboard and mouse is fine, however I'm surprised to see a lower power - plug is soon message. Isn't docking station supposed to provide power to the laptop?
I bought this inspiron 15r 5521. Its approx 2 year old. There was warning in battery status in the PC checkup. Few days afterwards the laptop did not start up. I searched and did a hard reset..BUT when i shut it down or hibernate . again its like dead and i have to plug in the power cord for 20 min and do a hard reset to turn it on . It also happens that if i shut down while the power cord is plugged and i take it out and again plug it , it stops charging..(again need a hard reset).
well I have a l702p 3d, I connect it to my samsung smarTV and it works wonderfuly (hdmi ofcourse), but I have a FLATRON W2243T LG monitor (it only has DVI and VGA ports) I try to connect it using hdmi-dvi adapters but the laptop does not recognize the monitor!
My aspire v3 laptop doesn't recognize a 2560x1440 monitor I connect to it - it only gives me the best option as 1920x1080. I've down loaded the latest AMD Radeon hd 7660g drivers but it still won't work.
I have an HP Pavilion m6 running Windows 7 Home Premium.
My workplace installed a router a few months ago. It's a Cisco E2000. My laptop will not recognize the wireless signal from the router. It recognizes about 10 other wireless signals from other locations outside the office. My phone also recognizes the router and can connect to it no problem. I've installed all the updates for Windows 7 and for the HP laptop. I've also installed the latest driver for the wifi card in the laptop.
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.
I have just upgraded my Dell Inspiron 15 (N5010) from Windows 7 to Windows 8 Pro I need to update the ATI driver but Dell does not recognize the Windows 8 Pro OS. Dell only shows the 2 previous os's on my system Windows 7 and Vista. without the driver I am having problems viewing pages. Below is my system info
OS Name Microsoft Windows 8 ProVersion 6.2.9200 Build 9200Other OS Description Not AvailableOS Manufacturer Microsoft CorporationSystem Manufacturer Dell Inc.System Model Inspiron N5010System Type x64-based PCSystem SKU To be filled by O.E.M.Processor Intel(R) Core(TM) i3 CPU [code]...
The USB ports can recognize USB mouses and keyboards. However, it will not recognize external HDDs or her Ipod. So far, I've taken the liberty of reformatting her computer but the problem still persist.
I've updated all the drivers to the latest editions and I have tried multiple methods of resetting the USB. (Complete power down of the laptop, Uninstalled the USBs from Device Manager) Does anyone have any suggestions?

As this HD was often recommended in Internet forums as a replacement for the built-in Fujitsu 60GB, I bought it and tried to make it run today. Unfortunately, the HD is not recognized.
I used Acronis True Image to copy the contents of the old HD onto the new one, but in Bios only the value for the old HD appears (58GB).
I removed the battery, I tried all kinds of boot-ups to no avail.
I just bought an SSD for my Insiron 3737 along with a caddy so I can replace the CD-RW with a 2nd hard drive. The laptop came by default with a WD 1TB hard drive which I removed and replaced with the new Intel SSD, the WD drive took the place of the CD-RW.
At first I had trouble booting when the WD drive was connected since that one had Windows installed on it as well. After formatting the WD drive I can now boot but a new problem occurs. Windows sees the WD drive a healthy, ready to use drive for a few seconds or minutes after booting and then the hard drive simply vanishes from Disk Management.
I checked the caddy even took it back to where I bought it from so they can check if it's faulty but it seems that's not the problem.
I have an Inspiron N5010 It is just under 2 years old and on it's second charger- the first was replaced by Dell when it stopped working altogehter after only 8 months of use. However for a few weeks now it has intermittently failed to recognise the charger. Three days ago it stopped recognising the charger altogether. I cannot use my laptop unless it is plugged in.
My Dell Inspiron 15 (7537) simply does not recognize the built in touchpad for a couple of days now.
I did run all the tests even the ePSA test and all passed with OK, but never the less there are not tests for the touchpad.
If I unplug the external mouse the mouse pointer dissapears, as a sign that there is no device present.(I tried to install and reinstall the synaptics drivers - Input_Driver_15K08_WN_17.0.13.51_A02 ) but no luck at all.
Furthermore, I tried to boot the system using the windows 7 and 8 installation media, as well as Linux Mint, but there is no mouse pointer unless I plug in an external mouse.
It seams to me that the hardware is faulty.
I still have 1 more month left from the standard warranty, what should I do ?
After replacing the fan, I have a power up issue with the laptop. Basically, the laptop will only power on with the power cable disconnected at the motherboard. It was by mistake that after the fan was replaced and everything was put back together, that I noticed that the battery was not charging.
I then reopened the machine and reconnected the power cable to the motherboard and nothing - no power.
When plugging in the power source with the battery in place, the LED adjacent to the power socket lights up WHITE then stays ORANGE and will not power up. No other lights, no fan noise, nothing.
If I remove the battery, the LED adjacent to the power socket lights up WHITE and stays white however will not power up either. Same agin, no other LEDs, not fan noise, nothing.
I have now opened the machine back up and disconnected the power from the motherboard. Put it all back together and the laptop powers up as normal with the battery and it works fine. (Well until the battery runs out anyway).
