I bought my HP laptop to do some datalogging for my Dodge truck.  I have the file ready to send out, but I cannot get into my Yahoo email account.  I keep getting a manage or dismiss box at the top of the screen.  My password that works on my iPad and desktop, does not work on my laptop.  I try updating password, delete Yahoo account and add it.  It also says not synched, so my Yahoo email on my laptop is not showing any emails in my inbox.
