It has only 492 MB of ram memory, and I tried to add 512 MB 2700 at 333Mhz replacing one module of 256MB 2100 of 268MHz. It doesnt work because the system only register 192MB.
The same memory works correctly in another PC Toshiba Satellite.
When I install the same modules that I had initially then the computer is starting for 5 seconds, and later stop and restart the power up again and so on. During these 5 seconds I hear the HD runing
I thought that perhaps the hard disk was disconnected. I verify the HD connections and were good.
Also I verified the voltage output of the external power module and it was correct.
please sugest me what I can do or verify before sending it to a repairing service, that in my area is inefficient.
Waiting your comments.
Thank you for your help
