all HP are onsite service at the moment, as their service centers are closed.

However, there are no such thing as complete 1-1 exchange except for printers.

all models, even those purchased before they started the onsite service will have onsite service as there wont be service centers to service them otherwise.

just call and arrange a service and it should take just 2-3 days for normal consumer models.
1-1 exchange may be available for certain enterprise models, but typically even commerical laptops only have 1-1 for parts, not the whole thing.

If DOA case, dealer will handle, not you, unless of course, you bought it directly from their website.
and also CN case, where parts are not available, else, rarely do you get full 1-1

which manufacturer so good, give you 1 - 1 laptop for most case?

mathafather..........DOA means CN case and is the only case that you're typically granted 1 to 1 la,
most of the time, end users deal with dealers, rather than manufacturer directly because manufacturer will take time, while dealer will have ready stock......

find me a brand that will offer 1 to 1 exchange for a consumer PC b with just a screen problem or just a keyboard issue, with spares available easily

yea, which is why I was wondering which brand was good enough to offer 1-1 to small issues.

you don't have to be a big player to know DOA case can be claimed even for things like missing keys or dead DVD drive, but what you commented earlier implied that TS could be compensated with a brand new machine for those kind of issue, even months after his purchase.
