Hello,
at first excuse my very bad english.
I’ll try to explain my problem, i hope you understand.
My problem:
If I boot from the opensuse 64bit DVD (Ver.11.0/11.1/11.2 - its the same effect)-the bootmenu appears-i choose to install opensuse in the menu-
now the kernel is loading-then i see shortly the next screen-and then
my notebook reboot.
I have the effect also in the live-version 64bit.
The 32bit version works properly.
Now an important effect:
if i remove one ram module (then i have 2GB), the installation works without any problems!!!
2 new RAM Modules i build in –> same problem
i haven’t any problems with vista 64bit or Ubuntu/Kubuntu 64bit, but the same
effect with mandriva 2010.0 64bit.
Another important Info:
I removed one RAM Module so that i have “only” 2GB Ram on my laptop.
Then i install the 11.2 64Bit Version, after installation is complete i build in the next 2 GB Module - always the same effect, while the
system is booting the laptop is rebooting…
i go crazy-need an idea !!!
Thx for the answer,
i also thought to hit the esc button.shortly before the PC reboot
there appears a lot of messages at the same time.
Is there a possibility to show the messages slowly???
The resolution,i am not shure but i think 800x600 or 1024x768.
Sounds like the 2GB module you take out is defective in some way.
It doesn’t bother the 32-bit version because a 32-bit OS can only use 3.25GB and thus is not able to use the full 4GB. Therefore, it never accesses the faulty areas on the second memory stick.
You could still do a memory test to be absolutely sure (although that would need to run for many hours), but I’m pretty sure that’s the cause of your problem.
Resolution is not the problem AFAICS. RAM is excluded. So something else is wrong. I suggest you install 32bit. Unless you’re going to use the laptop for heavy video processing, 3D rendering etc., but then I would doubt if a laptop is the ideal machine for it.
I have tested the 11.2 64bit DVD at
another Notebook -anonther Lenovo N500 (exactly the same model)
The same problem - reeboot after loading the
bootkernel.
Its definitely not a hardware error.

I have seen cases where there is a drive problem with 2 memory modules
installed but not for just one. If OP could try BIOS settings to set
memory timing more conservatively the issue may go away.

Perhaps there may be a way to replace existing RAM with more
conservatively rated modules.
