Frequently Asked Questions (Lab Verified)
What does Alienware's Stealth Mode button do?
Pressing F2 instantly switches the thermal profile to quiet, dials down fan RPM below 35 dBA, and turns off all RGB lighting.
Why did Alienware remove the thermal shelf?
The previous rear protrusion made the laptop too deep for standard backpack sleeves. The R2 redesign incorporates redesigned Cryo-tech vents that eliminate the protrusion.
Does it support dual PCIe Gen4 SSDs?
Yes, the m16 R2 features two M.2 slots allowing easy storage upgrades.
