I’m having the exact same problem. I can’t even run recovery again. Mine is an e260. I know it’s old but it’s sturdy and I like using it.
No matter what I do, I only get the white screen. I don’t even get a locked error when I turn it on with the lock in the on position. I don’t want to get rid of this. Customer support will only handle this through email now.
Any help would be greatly appreciated.
