Windows 10: Laptop is lagging, and audio distorts when not charging.

So I got an Acer Nitro 5 about 2 months ago, and its been working fine until recently. In the morning I decided to try and clean my cpu fans, and when I got back I booted up my laptop, and I noticed it was super slow, and whenever I played a game or watched a video the audio was distorted. I also noticed when starting up the laptop that the battery had a grey X icon over it. But when I charge the laptop, it works perfectly. Please help me.

Laptop won't charge and speakers distorted when plugging in charger

I have a Dell Inspiron 15 and whenever I plug in my laptop charger the device starts to lag, my speakers become distorted and the laptop indicates that it is plugged in however not charging. The sound distortion also occurs through headphones when charging.
This is a new device I have had for five months. I receive a warning notification whenever the laptop is plugged in that I need a 45w or higher charger however it is a 45w cable. When unplugged I have none of these issues and the laptop works perfectly.

 

sound distorted after windows 10 anniversary upgrade

This is where I'm at on my HP laptop with Windows 10 and the Anniversary update.

I completed step #3 "hardware and sound" but that took me to an option for "sound, speakers." There was no "properties" as step #4 suggests. I selected "sound, speakers" and then found "properties." After selecting "properties" there was no "enhancements
tab" as step #5 suggests.

Regardless, I then uninstalled the realtek audio driver. I noticed that when I did this without restarting my laptop that the sound was now tinny, but not distorted as it was previously. After restarting, the sound was again full, yet distorted.

Realtek still shows in my programs list, though it shows no memory is used.

Thanks for your continued help.
