So those of you who have seen my many rants on here about this particular laptop of mine, a Compaq CQ62, will know its been giving me trouble since the day I purchased it. Withen the first year, its been replaced entirely due to a hardware failure they couldn't identify for some reason, even though it was clearly a hard drive issue. Not long after that, hard drive failed again, but they replaced just the drive this time rather than the whole computer. Fast forward to the recent months, cooling system failed and needed to be replaced. Now again today and for the last few days, performance has been slower than usual, and its overheated so bad that not only does the fan opperate extremely loud, its crashed due to reaching a temp of over 90deg Celsius apparently. Thats extremely worrying. That happened right before it was sent for repair last time. 


Now due to this being now the 4th time its needing repair, am I fair enough in demanding a refund of this unit? If its failed 4 times withen 18months of purchase, whats it going to do further down the line? The CGA states if they cant fix a problem or provide a solution then I can request refund/replacement or whatever, and they clearly haven't fixed it in the last repair session. Its getting really annoying now and having to deal with Harvey Norman is frustrating since their CSR's couldn't really care about helping. Its just a formality that I have to take it to them basically.

What would you recommend?
