Bleeping Computer helped me a lot at a previous time - perhaps you can help me again.
I have a Lenovo B575 laptop. I upgraded to windows 10 and, while I am generally pretty happy with it there are a few key things.
1. It won't wake up. When I originally had it upgraded, if it went to screensaver, it would not wake up. I would have to close the screen and wait and then reopen for it to restart. Then I reset all the "personalize" setting to the default settings. Now, it seems to wake up but, if the screen is closed, it is a crap shoot whether it will wake up when I open the screen. Most mornings, I open the screen and end up having to restart the computer.
2. While the computer mostly stars OK (60 second boot normally) it takes a while for the CPU and the hard drive to go below 100% to allow me to use it.
3. Not sure of this is related, but, every once in a while ( 2-3 times a night) Chrome will spin and spin but not load the page and tell me the computer is not connected to the internet - when it is. after about 5 minutes everything starts again.
4. Finally, I use the free version of Avast - every once in awhile, I get their "upsell" message. Typically it tells me there are inefficiencies. I took a screenshot and don't know if it is legit or whether I can do something about it without buying their product.
thanks in advance for your help with this.
