Asus has quashed rumours that adding extra RAM to its 8GB Asus Eee PC will void the warranty.

The ultra compact UMPC delivers 512MB. But, say web reports, a warning label on the computer stated that opening the RAM slot to add more memory would constitute a "warranty violation".

Asus has now released a statement that suggests this was a mistake: "Asus wishes to assure its customers that merely breaking or removing this kind of seal will not void the Asus Limited Warranty".

"Although Asus recommends that customers use Asus-approved service facilities and components, Asus is committed to honoring the terms of its Limited Warranty and making sure that its customers are free to make appropriate hardware and software modifications and upgrades, regardless of whether the service is performed by an approved facility, a non-approved service provider, or by the customers themselves."

"Asus will replace the warranty label with a label to warn users that Asus will not be responsible for the damage caused by improper hardware change."
