Thanks John, this is helpful. I have bought an external disk drive(LaCie) from Apple store yesterday to backup my machine. As they told me my external storage device has broken. The team is able to do it manually but they are unable to use the Time Machine to help me to back up due to various reasons and partially my laptop is vintage, i am not sure what happen too, i know nothing about it. I will need to explore Time Machine later if i would need to change to a new Macbook.
However i dashed down to the nearby Apple Service centre yesterday afternoon. I had spent about 3.5hours for them to figure out and solve the issues about 6 persons supporting it. Due to my laptop is being told a VINTAGE, what a shame, nothing much they could help further unless I bought a latest version, bought a new one is no way, i had been struggling to use and understand macbook since i bought it at my own use and never have chance to learn to use about it.
But, at least the team at the orchard service centre is manage to help me to upgrade to the macOS Catalina and solve some of the compatibility issues after i got home and notice it, like some movie or mewatch from internet, some graphic is blank and only able to hear sound but Catalina works.
Aside, I have told the team another problem, the side of the screen has started to become white patch or any words/tool bar along the edge won't be able to read or see unless i use extended Monitor.
My laptop is still looks news, keyboard is good and able to function at minimum - turn on/off, sound good, use page, numbers, keynote, upload pictures (although not much fantastic functions compare to window 11 Microsoft excel, words), i do not think i need to change or buy a new machine unless the Apple store won't support anything VINTAGE, and it sounds unwelcome when nothing of the team know much about vintage here.
Have a lovely weekend!
Much Thanks
