Black screen Toshiba Mini NB205-N330BL 10.1-Inch Royal Blue Netbook‏?

Hi everyone.

I need your help with this issue. It all started when I pursued upgrading the memory from 1GB to a 2GB card. The 2GB is a Centon 2GB667LT. DDR2-667/533/400 SO-DIMM, 200 pin.

I'm not even sure how it happened. I assumed the computer was off when I pulled the battery out and not hibernating. I know the lid was closed. I also checked the port where the cards are to be plug into. I do not see any apparent damage to it.

Since I have the two cards I have tried with each and without any at all to start etc but nothing happens. I do not get cursors or any noises. No chance for safe mode or else it is just black.

The only indicators that lit up are AC power, Netbook On or Off, and battery. I also tried to start with AC power or battery alone but it does nothing. I have tried to start with CD DVD drive with a repair disc in it but nothing happens. I have been carefull to avoid static electricity from harming anything by taking precautions and caring while changing the cards. My netbook was in excellent shape. I do not know if it worth it to mention I used Bitdefender as antivirus and Windows Defender & Firewall are off to avoid conflict between the anti virus and them. Please help me I'm going on a trip next week and do not know what to do to fix it?

Best regards to all,

Luis
