So, my issue that ive looked everywhere for a solution to is this. I was about to give this laptop to someone and I reformatted the hard drive to clean it up before doing so. After this I went to dells site and loaded up the drivers for this machine. All is fine up till this point. Then I updated the bios to the newest version a12, and all went fine.
Well, later that day I needed to unplug the laptop and go to a different room and It just turned off after I unplugged it. It wouldnt turn on with battery power either. Plugged it back in and it loads fine but the battery is stuck on 36 percent charge and says not charging. Now im getting a message saying the battery needs to be replaced as well, which is *** because I know that the battery was working just fine before this day. Not only that why wont a battery with 36 percent charge turn on the laptop? Its got the flashing red battery symbol when powered on with the ac adapter but without the computer on, but still plugged in, the battery doesnt charge or have any lights.
I have already tried the uninstalling of the acpi trick, as well as the taking the battery out while its running, or taking it out purging the power and reseating. Ive tried all the common tricks to no avail. Not sure whats going on but I know this battery was good, and it still says 36 percent but wont charge and wont power the laptop on. Hope someone can help.
First check: make sure the BIOS (F2 at powerup) recognizes the AC adapter. If it does not, the battery will not charge.
If the AC adapter is not recognized, try another Dell OEM adapter. If that doesn't solve the problem, replace the DC jack:
And if that doesn't solve the problem, replace the mainboard.
If the AC adapter IS recognized, but the battery will not charge, unplug the system, remove the battery and hold the power button for 30 sec. Try again -- if the battery still won't charge, odds are the battery itself is bad.
If the battery is original to the system, it's about four years old - well past its expected lifespan.
I have a Dell Vostro 3500 with Windows 10. The power adapter was working fine till last night till I plugged it in into another Dell Inspiron. I put my charger back into the Dell Vostro and it gave an error at the POST screen that its not a Dell specified charger. I tried a lot of methods after reading online, even updated the BIOS from A6 to A12. Tried the Dell Inspiron charger and it worked fine but whenever I put in the Vostro's original charger, it said Plugged in - Not charging. So this is how I fixed the issue in the end:
1. Pulled the power cord out and the laptop was running on batteries.
2. Uninstalled the Microsoft ACPI-compliant control method battery from the battery drop down menu in Device manager. The system asks you for a restart. Press Yes.
3. When the computer is booting up before it even shows the Dell splash screen, press and hold the power button, so it completely shuts down.
4. Plug in the power cord of the original charger but DO NOT plug in the battery.
5. Start up the computer in the normal way, log into your account and when you think that all of the background services have started up, shut down the computer properly.
6. When it is completely shut down, plug in the battery and start up the laptop.
7. You will see that the battery LED light would come up and that's it.
It worked for me.... hope it does for you too
