Our service charge should basically cover you for all minor issues and diagnostics. Minor software issues and stuffs can be covered within the $65. However, if there are any purchases or replacements of hardwares, there will be additional charges. It would be $65 + whatever prices quoted for the hardware.
For example, your computers HDD is faulty diagnostics suggest a replacement. It would be
$65 + HDD cost. ( In some cases, brand new HDD require seperate Operating System Installation. If you purchase this separately, it will add on to the cost )
