This is multiple stange things with my laptop. I have a Aspire v3 (va70) and when i update the Nvidia graphics driver, it will not automatically shut down after the install and i have to manually shut the computer off. When i go to retart the computer, it will power up and go into the acer screen , but will refuse to go any further...it has a mouse pointer and the wireless icon flashes, but will not proceed any further than the Acer screen...finally figured out that to get it back to normal boot, i had to do an Alt +f10 , get into the recovery screen, and then exit out of that without actually doing anything. This would get it to resume booting normally from then on..have had it do this for at least the last three graphics updates..
The other weird thing is if i shut down the computer from windows (8.1), when i go to turn it on, i will have to pull the battery to get it to power on. Doesnt matter if it is on battery, power or both, still have to pull the battery. Next, when it does power up, it will be stuck on the Acer screen doing nothing unless i hit a button on the keyboard twice..once will get the hard drive flashing for a second , and then a second tap on a key will get the drive moving again and the little circle of dots will flash and it will now load windows..
Cant figure a cause for either of these...have reset the bios to defaults to no avail..cleaned the computer and virus/maleware scanned..nothing.. computer works normally otherwise
