Omni 220 - Memory upgrade

[barrykrish]

I bought a HP Omni 220 All in One PC this week. It has only a 2GB RAM memory.
I bought a compatible 4GB RAM for upgradation.
Now, I am not sure if I should try upgrading on my own or call a HP Support person, because there was a warranty seal that said the warranty would become void in case I break it.

What should I do now?

Upgrading memory won't void your warranty. The warranty simply won't cover the new memory if they don't work (although they may have their own separate warranty themselves).

Here is a guild that will help you with replacing the memory:

Thanks for the instruction guide.

With regard to warranty. There is a seal across the back of my monitor which would be broken if I tried to remove the back cover.

 This is my concern.
