Laptop doesn't boot after upgrading RAM
I tried to install 8GB RAM instead of 4GB. When I finished the replacement, I turned on my laptop, but the screen stayed black, no Dell logo or anything, no signs of booting at all (all the indicators were off). After 10-15 seconds it turned off by itself. After that the HDD indicator started blinking, and the other two indicators turned on.
Then I removed the new RAM and installed back the old modules. But I got the same problem - the laptop doesn't boot, there is no Dell logo. I tested both sets of RAM modules on my other laptop and they work.
How do I fix this?
P.S. I followed general recommendations and removed the battery before each procedure.
Es esta una buena pregunta?
