Our customer brought this NEC laptop to our office in Kawaguchi, Saitama because first she could not log into Windows. At the log in screen the password was always wrong.
Even after reinstalling windows it does not work well. We found that the keyboard of this laptop is broken and one key is pressed permanently. Because of that the laptop does not work well. However in this case we can fix the keyboard without replacing it as only one none important key is broken.
Please contact LoreaTec to fix keyboard or any other PC troubles.
