There is a bug in the Windows bootloader that I have yet to find a workaround for. Here it is and how to trigger it.
HIBERNATE the laptop.
Chnage RAM size.
The laptop may fail to boot and show a blinking cursor in the top left corner.
Sorry, I only know how to create the issue. I learned about it the hard way and to get out I changed the ram back to the same size then booted up but next time did not hibernate but SHUT DOWN.
I have not tested out the theory that booting off an UBUNTU CD may let us delete the hiberfil.sys file to correct the issue. You do that test.
I have an Acer Aspire 5610-2328, Windows Vista Premium. I upgraded to 4GB(2x2GB DDR2) of RAM. Was running fine for about 1 yr. Recently, laptop was giving me a blank screen. I downgraded to 2GB RAM (2x1GB). I ordered new RAM (2x2GB), but I am unable to boot computer, Is there something I need to do before installing the new RAM? Please help! Thank You!
