Im planning to buy Laptop atm, alot of the laptops that is on my budget range are soldered RAMs into the board, some do have soldered RAM onboard but has extra DIMM slot to put another RAM stick
The question is…
What would happen if a Soldered RAM fails but the Laptop have an extra RAM slot. Will the laptop still works even the soldered RAM fails but you have another RAM stick on the modular slot/DIMM?
It depends a bit on the layout of the machine. Sometimes laptops can run without the internal RAM with a little bit of work, some will not work unless the defective RAM chips are replaced. In any case it will most likley require intervention by a technician. Unfortunately it is very diffucult to find a machine with non-soldered RAM. However it is quite rare that the RAM dies on a machine that is treated well. If it falls to the ground a lot or gets slammed around/ the chassis is flexed, the chance for defects is bigger.
