4GB Memory Upgrade for Acer Aspire 5102WLMi
- by Richard Slater
I have bought a 4GB memory upgrade (2x 2GB PC2-5300 SODIMM) for my Acer Aspire 5102WLMi (Aspire 5100 Series) laptop, I installed the two memory modules correctly however with 4GB installed the laptop refuses to POST. I have tried the following:
Tried both 2GB SODIMMs without the other (Worked Fine)
Tried the original 512MB SODIMMs (Worked Fine)
Tried with original 512MB SODIMM and new 2GB SODIMM (Worked Fine)
Tried swapping over the 2GB SODIMs (Didn't Boot)
Left the computer for 10 minutes with both 2GB SODIMMs installed (Didn't Boot)
Checked latest BIOS installed (No Change)
The Crucial website said that the laptop supported 4GB of RAM as do several other sites through found through Google, up until now I was fairly confident this would work.
Couple of questions that would be good to have answered:
Question: Has anyone got an Acer Aspire 5100 Series running with 4GB RAM? Answer: Yes, I have now got one working with 3.75GB Usable, the rest is occupied utilized by the Graphics Card.
Question: Any tips on getting this to work; is there a CMOS reset switch? Answer: Yes there is, if both SODIMMs are removed two very small interlocking PCB tracks are revealed. If these are shorted together with a screwdriver the BIOS will be reset.
Thanks.
