Dell m4600 Demension Laptops with any i5 CPU and the low end i7, are only dual core as opposed to quad core. The secondary memory dim slots under the keyboard have been disabled by Dell at the factory.
The max supported by Dell on dual core CPUs is 16Gb. The extra memory Dim slots are permently disabled.

Hi Daniel,
The memory configuration in Precision M4600 is based on the processor. All 4 memory slots (DIMM) will work if the computer has Intel Core i7 Quad Core or i7 Quad Extreme processors.
Only 2 DIMM slots will work in configurations with Intel Core i5 or i7 Dual Core processors. Since your computer has i5-2540M processor, only the primary DIMM slots (at the bottom) are usable.
Please do revert for any clarifications.
