My E6410 has been giving me trouble with very slow bios post, not loading windows with flashing cursor,starting Windows and basically being a pain in the ***. I updated to bios (A16) no joy. I swapped ram, no joy.I reinstalled Windows, no joy.
Solution: I had a faulty USB port (black plastic casing missing ) and the pins were causing a short, by touching each other. I straightened pins, with long nose screwdriver (charger and battery disconnected) and it's been working like a dream since.
Hope this helps anyone with similar issue.
