If you aren't able to get into BIOS setup (F2 key) or Dell Preboot menu (F12 key), I suspect motherboard is faulty. However, if you're comfortable removing parts inside the computer then I suggest removing battery by following the steps I've posted above to see if that will get the computer up and running again. Please view battery removal in the link below.

If removing battery doesn't work, I suggest reseating coin cell (CMOS) battery.
Dell Alienware 17 R2 CMOS Battery How-To Video Tutorial
1. Remove coin cell (CMOS)battery
2. Press the power button for at least 15 seconds to drain all residual power from the system
3. Wait about 5 minutes ( or over night) and then replace coin cell battery. Assemble the unit and verify functionality.
Note: When the system is powered on, it will warn that the date and time is not set, indicating a successful reset

I can't seem to find an Alienware R17 S2 in Dell knowledge base. Please list exact Dell model number and version of windows. You could this by entering service tag number onto the link below. You should be able to see exact Dell model number in your Dell Product Support page.
