Non-booting Alienware M17x R4; continuous intermittent beeping at powerup
I purchased an Alienware M17x R4 notebook in May of 2012 so it is no longer under warranty. It has sustained no damage through any means.... no water spills, drops, etc. However, within the past few days, it has developed booting problems. Sometimes it would boot to desktop and others not, but would emit a black screen and an intermittent, non-cyclical beep about every 1-2 seconds. Now, it just gives a black screen and the rhythmic beeping. I searched online and found this issue reported elsewhere but found no solution. Some have said, remove the CMOS battery, the system battery and the AC adapter cord and hold the power button up to one minute, then put all back in and power it up. I did that several times and maybe one out of 3 times, the notebook would boot up properly. Yesterday, I found it would not boot but beeped as I have described and by removing the system battery and power cord, I could stop the beeping and then get it to boot to desktop again maybe 1 out of 3 times upon reconnect. When I did get it to boot, I ran Dell's built-in system tests and all came back without any errors. I don't want to send this unit in to Dell itself for repairs but maybe an independent shop if I can find one. I am stumped and would appreciate anyone's insight into troubleshooting this issue. Thanks!
