I am using an Alienware 17 with Windows 7. Intermittently, the 9, i, o, l, >, and number pad 5 keys stop working. If I long-press one of those keys for several seconds, they start working again... until the next time they become unresponsive once again (sometimes minutes, sometimes hours, days, or longer).
This issue has been occurring off and on for a few months. I just went through a month-plus period without any malfunctions of this sort, when suddenly they started up again yesterday.
I have removed and reattached those specific keys, but cannot find any crud or other physically-limiting element beneath the keys. The laptop has never been dropped and has never been spilled-on.
Any ideas on troubleshooting/fixes?
Thanks!
