hey guys, im a M15x user and i really hope someone can help me with a problem that i've been having with my laptop. My battery is now plugged in but not charging, before this all i have to do is just restart or unplug and plug it in again, but this is not working this time, then i looked for solutions online but none of them are working for me. Now i am trying to update my BIOS but i dont really know how to do it, i've downloaded the file from the Dell website and already unzipped the file, but i have no idea how to proceed from here, also tried searching online but couldn't find anything instructions that are specific to this model. thanks in advance for the help!

i went into BIOS but i couldn't find that option, the only thing that i saw was something about giving out a warning when an incompatible "power brick" is detected and another one about having usb devices wake the computer from sleep mode, but funnily now everything is back to normal and my battery is charging again.. maybe i should give dell a call to replace my power adapter soon haha.. thanks for your feedback anyways!!
