Thanks - I have purchased this device from UAE & can you suggest me dell authorized service center as i need only OEM center for repairing. Also if we book motherboard how long days it needs  Yes as you said need to add service warranty for 15years . Bcos not possible to change a motherboard yearly once.  Oly myself facing issues with this model ? What could case this kind of issues in a new  pc like this.  Here even if i need i cant make direct purchase from dell or dell wont exchange this PC with new one  I have worried like ordering a motherboard with older 10th generation & i think it would be stocked one . Why cant we upgrade with 12gen motherboard for model 9500 so that it would be newer hope there wont be issues like this ..
Dear,  I have purchase this laptop an year ago & i'm using this lap  for my business use. Not aware how come such an expensive PC get mother board failure like this within year . Any how now i need to replace it as soon as earlier but not getting proper support from dell team .  How much it cost  Do i get any warranty upon replacement or again within a year i same issues will persist ? For everything i need contact third party were they claim need to get reply from dell & this work needs 8weeks of time.  Such a bad experience with dell now.
