I've having a bad week with PCs, this is my second problem this week!
My Dell Latitude 120l needed some new RAM, the old RAM worked but was only 512k. I put some more in (from an old Dell Inspiron 1501 that no longer worked), having following the instructions, taking the battery out, earthing myself etc. I didn't check if the memory was compatible, because I stupidly assumed that all Dell RAM would be compatible with all other Dells.
I turned the Latitude back on and I got a message saying new memory installed. It asked me if I wanted to enter the settings screen or continue. I chose to continue and Windows started normally.
It worked for about 10 minutes and then shut down. It was out of charge and I hadn't realised it wasn't charging as normal, despite the power charger being plugged in.
It now won't turn on at all.
I've tried the following.
1. Checked the power charger is working.
2. Removed the battery and replaced it again.
3. Tried a number of combinations of memory, including returning the original memory to the laptop.
I still have no power. No lights come on, it is completely dead, as if the power supply is not attached at all.
Please help, thanks.
