Alienware M15 R4 shuts down on Razer cooling pad

Yep. I just confirmed that the culprits were the magnets on the Razer cooling pad. They created a magnetic field that would shutdown my Alienware M15 R4 laptop whenever I placed it on top of the Razer cooling pad.

Fix:

• Dissasemble Razer cooling pad: Take off all screws on the bottom to include those under the rubber strip and remove bottom cover.
• Drill a hole on top of the magnets removing plastic. I used a Dremel rotary tool with the drill attachment.
• Use a punch tool and hammer to punch out the (8) magnets.
• Optional - cover the holes you drilled with electrical tape.
• Reassemble Razer cooling pad.

My Alienware M15 R4 Laptop is now working flawlessly with the Razer Cooling Pad.

Confirmed. Magnets were the culprit.

Disassmebled, drilled and punched out 8 magnets, re-assembled.

Works 100%

i have a dell G15, and the screen kept shutting off as described. I had trouble removing the screws from the back, so i used a shaping tool on my Dremel and cut the two magnets out, my cooling pad has eight indentations on the front, but only the two center sides had magnets. once i cut them out, my cooling pad works properly. The insert covers the cut openings. 

Alienware Aurora with even worse issues. Slight movement causes the Hall effect sensor/shutdown as noted by others. However, also interferes with wake-after-sleep with VIDEO_TDR_FAILURES and instability with the GFX/Video cards with screen locks and resets. The laptop was fine before adding the pad and all hardware tests show no problems.

Removed the cooling pad and no issues since. It’s a nice cooling pad that integrates well with my other Alienware LED controlled devices, so will DIY the magnets out like others.
