Dell Inspiron 15 laptop shut down

for sure shut downs have many causes, overheating tops the list.
NO PC told . 15" laptops lots of models (vast), for just size. 15"

the big battery inside varies by all versions, from old that just drop off bottom to deep inside
I test all laptops first with the big battery removed,when bad it can caused the PC power bus inside to overload.
tested on AC power pack only, no BIG BAT.
sadly DELL removed the bottom sticker words, of model #

Dell Inspiron 15 3565 / 3567 ( just one of 100s of models 1 example)

gone is the model now (newer), it is now a secret ( why body knows)
but the tag there shows the service tag.#
and at dell.com you tell them there in the tag box online the tag number and that then tells you real model you have. vast exit word wide.
that is the new dell way of doing business, now. no model # on it.

loss of power
or overheats
and 20 other reasons./ (bad parts inside count them any can fail)

lets say the AC pack is bad or intermittant or its cables or jack bad (cracked?)
then the battery goes dead. and PC goes dead.
see? it has 2 power sources,. if both fail so does the PC. loss of power or overheats and 20 other reasons./ (bad parts inside count them any can fail) lets say the AC pack is bad or intermittant or its cables or jack bad (cracked?) then the battery goes dead. and PC goes dead. see? it has 2 power sources,. if both fail so does the PC.
