Weird upgrade 10.04

[Augusto Chan-Tay-On]

Hi, I am relatively new with Ubuntu, and have almost no
hardware skills (I understand software better).

I have  an Averatec  AV3360-EH1 (centrino)  old laptop,
with 80 GB  HD and 1  GB RAM. Originally,  with Windows
XP, and now running Ubuntu 9.10,

The only thing I couldn't make it work, is the SD card;
instead, I am using USB adapters for that purpose;  so,
not big deal.

I  tried  the  new  Ubuntu  10.04 clean install, and my
laptop went into a kind of gray screen with no  further
activity.

I reinstalled Ubuntu 9.10,  did all updates, and  tried
the upgrade; it went to the same situation.

After  reboot,  a  "shutting  down"  continous  message
appeared every second.

I installed Ubuntu 9.10 back, and everything is OK now.
Maybe I will try 10.04  again, later; if no success,  I
will wait for 10.10 to try again.

It is supposed that a new version corrects and improves
what is already included, and adds new features; it  is
weird to think that a new version disables or gets  rid
of some features already working well.
