I'm experiencing boot up problems with my two days old Inspiron 15 laptop. Every 4 to 6 attempts to power back on after normal shutdown I have to remove the battery, wait 10 seconds and put it back in before it starts up. It will then start up normally for another 4-6 attempts. I kept it plugged in thinking perhaps the battery was just draining but when I looked at it after power up, it was at 64%. Also if it's plugged in it won't start sometimes. Is this a common problem with Dell Laptops? My previous 6 laptops have all been HP and this is my first Dell. Thanks for any help and suggestions everyone.
