I don't know why this is happening is it just a windows 10 thing not being accurate, i have done a reset to get rid of all the HP bloatware, I have never had the signal in the taskbar before so i dont know if this is normal, but it will show full signal but then go down to one bar then back up all in about 20seconds, Is there some sort of hibernation that needs to be turned off? I say hibernation because it tends to do it when im not using the laptop.
