Hi, my daughter has a Dell Lattitude CPi, when she now tries to power up, the indicators flash 5 -1 - 2. According to Dell online, this means no usable memory.
Is there any way to fix this?
The unit is 2nd hand and I do not have the diagnostics disk

Take the battery out, unplug the power supply.
Remove the memory chips and re set them in the slots.
Do not touch the contacts, use an anti static wire, or if you do not have one
Keep one hand on the case at all times.
You must take the battery out, unplug the power supply before you
take the chips out. Carefully snap them back in, plug in the power supply
and see if it boots. Did you get the service tag off the laptop and search dell com.
May give you more info and a PDF to print out, repair disks, drivers, help files …

Many thanks Gort, that worked a treat.
If you have time, could you explain what was wrong.

Maybe Gort knows better, but it would seem to me that your RAM had worked its way out a bit. This can happen due to jarring the laptop or from heat moving the RAM in small amounts over time. Removing the battery and the power supply ensured that you wouldn't run the risk of shorting out something while you were working inside the system. Removing and reseating the RAM allowed for the pins to make contact again.

Wonderful you got it working.
Yea, the chips some times need to be reseated in laptops to insure contact.
I also see this in computers I received , will not boot.
Reseat the chips, cables and add in cards and it works for years.
