Hello
My laptop screen keeps turning white and sometimes flashes before shutting down. This began after approximately one year of purchase and has continued ever since. Last year it was away being repaired under an insurance policy more often than it was in use. I understand from the pile of paperwork that the master board has been replaced twice, the wireless has been lost and then reinstated and the registries have been lost and replaced - all as a result of the white screen problem. Each repair has resulted in my laptop being wiped clean. Please can anyone offer advice as Knowhow are unable to fix this problem under the extended warranty which is about to expire.
