Solved RAM Upgrade Startup Problems

Specs: Windows XP, Intel Celeron1.4 Ghz / 500k
I have an Acer Aspire 3502 wlci laptop. Purchased 2 PNY 1gb DDR PC2700 cards to replace 256k OEM. With both 1gb cards installed the laptop will power on but not boot everytime, it might take a few times of powering off and back on before it boots. Once it does boot I can eventually get into windows, but applications don't seem to run as fast as I anticipated. Originally when I was able to boot I would get error screens, such as error 0280: previous boot incomplete - default configuration used.

I tested startup with only one of the 1gb cards and there was no problem and tested both cards independently to see if one might be defective. Each 1gb card also worked with an original 256k card in the other slot.

Not sure what to do. PNY suggested flash BIOS, but I could not find any support for my BIOS, Phoenix NoteBIOS 4.0 Release 6.0 4/19/05. BIOS version ZL6 S3A08

Thanks for your help.

perhaps it has a 1g max.....two 512's or 1 1g stick......should give the max at acer.

Acer aspire 3500's says 2g max.......using 512sticks.....maybe it has 4 ram slots on the laptop? Many have only two ram slots. It shows DDR333 sodimm ram. Thats the specs on a 3500, not sure the difference if any with yours.

I believe before I would flash the bios just because PNY suggests it(one wrong move, or accidently you flash it with the wrong bios, etc, and you have an expensive doorstop). I know it sounds redundant, but I would go to, and use their system scan to evaluate exactly what you need, and how much, and what type. If you look at your computer specs, it looks as if you have what you need, but you never know. A second opinion never hurts. I would always try to resist a bios flash. According to the specs your computer should take 2gb, 1gb in each slot, so why should you have to flash the bios to get your computer to use hardware it should use normally, doesn`t make sense. Use the system scan at crucial to ok that, and read all the specs of the ram Crucial suggests, and compare it with the specs of the PNY ram. I am not affiliated with Crucial.

Thanks Ike, I just did a scan and these are the results.

Memory:DDR PC3200, DDR PC2700
Memory Type: DDR PC3200, DDR PC2700, DDR (non-ECC)
Maximum Memory: 2GB
Currently Installed Memory: 512MB
Total Memory Slots: 2
Available Memory Slots: 1


Each memory slot can hold DDR PC3200, DDR PC2700 with a maximum of 1GB per slot.*
*Not to exceed manufacturer supported memory.

Right now it looks like it's only recognizing the 1gb ram closest to board and only 512mb of it? Is that the correct interpretation? Right now I've a 1gb ram in each slot. Crucial recommends either 2 1gb DDR PC3200 or DDR PC2700 CL=2.5 • Unbuffered • NON-ECC • DDR333 • 2.5V • 128Meg x 64. The two oem 256MB chips I removed were DDR PC 2700S - 333MHz - CL 2.5
