If that were the case (Current host going belly up,) would 'you' still 
have access to your information (to then transfer) or might that be

Temporarily, while the hosting/forwarding company were bust or
malfunctioning, then I presume yes, you would lose access to data such
as incoming emails, which you could probably never retrieve; however,
you _would_ retain the domain, and could eventually instruct some other
company to handle it for you. You'd lose incoming emails in the
meantime; if you really want belt and braces, register two domains (such
as .com and .co.<country>), and have them hosted by different companies.

Of course, make sure that when you register the domains - even if you
have the handling company look after the registration for you - that
they're registered in _your_ name, not that of the handling company.
Good handling companies will do this, though it may not be their default.

During any such hiatus you'd also lose control of any website they host
for you too, and information from it (such as form input) - but, again,
you should be able to transfer that to another provider. (Good ones
should be knowledgeable about helping with such a transfer from
rogue/dead ones.) Of course, you should always keep a local copy of your
website anyway.

(This all in theory: I have no experience of a bad/fasiled hoster! I did
change hoster - from tsoHost to Krystal - but that was only because the
former switched to online assistance only, closing telephone support;
they were otherwise fine. [And in practice I _think_ all my
communication with Krystal has been online/emails anyway; I just didn't
want to lose the _option_ of telephone contact.])

Ah, a fine piece of cost benefit analysis. An example to us all... The 
cost of the wasted minutes moving the laptop versus the cost of a new 
one....and its storage space...

It worked out fine. I used a pair of wired headphones, and battery. It 
used 6% of the battery in 20 minutes. Previously I had to copy the TV 
serial I was watching. I don't have a fast WiFi AP so it took some time.

Is the display blank (bad LCD, or LCD wiring) or is the graphics visible if you
illuminate the screen strongly nearby (bad backlight, backlight
wiring, or backlight driver)

Please, you should read the entire thread, as this was asked and 
answered back in July, and I decided not to attempt a repair. When 
needed, I connected an external VGA display.

It is the backlight which fails. Indeed, illuminating with a strong 
light makes the text and images visible.

Usually it's a failure of the backlighting
