Only one memory bank works now. The one closest to the motherboard is the only one that works. just seems like a coincidence that right after I flashed to 3.13 it stopped working. Worked perfect before.

Not sure what’s going on but it does look like a coincidence. Is there any way to downgrade the BIOS. Do you want to try that?

I have a BL51, Aspire 5100. I have 2- 2 gig memory chips and they were working perfect. I upgraded the CPU to a TL-50 and flashed the bios. Now both memory banks won’t work. The laptop will only run with 1 -2 gig chip. It doesn’t seem to be the chips. I’ve switched them and they both work but only at 1 chip at a time. I also put the chip in another laptop and it was fine. Any thoughts on what it might be?

Do you mean one memory bank stopped working completely, or you still can use both banks but only with one module at a time?

I have a Acer Aspire 5100-5674 / model BL51 and I need to replace the motherboard but on Ebay got many of them.. what’s the reference number or code to buy that match with my laptop?

Take a look at the sticker in the memory compartment and search for the motherboard part number. It looks something like this MBABE02001.
After you find the part number, search on eBay.

I had to adjust the cable for the LCD cause it was blinking.
Since I knew how to find it… peace of cake with this tutorial.

And the best is that I saved some good money.

God bless ya!

Thanks.

I have an acer aspire 5100 and just looking to upgrade the memory on it. Have you got a link to some that would be suitable please. Looking to go to 4GB if thats possible?

Acer Aspire 5100 will take up to 4GB total. You can install up to 2GB memory module into each slot.
Use PC2-5300 DDR2-667 200pin SDRAM SODIMM.
