why not post what PC does,with no battery IN IT and the NEW power pack is used? this be first first.....!!
if that fails wrong pack.
only 3 possible reasons,
1: new battery is bad, (stuff happens and if china cloned x10 that)
2: wrong pack (i bet this is it, and hope so)
3; PC chips blown out (there are 2, a power reg, and charger reg)
so how do we avoid guessing?
well ,first is does it run with no battery and not stated by you yet.
the wall pack has to be 2 things to BE correct.
1: 19vdc, is it?
2: and watts, my HP elite book as 3 performances opens when new. (actually 5x3 permutations in fact)
A: faster CPU, $$$ 5 choices, the i7 is top and sucks power like mad.
B: one of 3 GPU cards inside, one sucks power like mad.
Mine has both, and needs the HP 100watt pack or WILL FAIL.
Mine is also the most fast of the model line
speed sucks power, in computers.
so learn what your HP needs. first.?
if you bought it new, then pack is correct, and states on the side of
is 19vdc and watts. so read that now, and match that.!
i bet you only guessed ,right?
if you did not buy the LT new, then you get to ask HP what you have.
ever heard of HP.com?
go there and ask,? magic happens, FACTS ! endless....
and HP has records based on Serial numbers. on yours.
this serial tells them what you got DAY 1. (we are NOT HP)
Just like a car, ordering the huge V8 sucks more fuel.
I cant see under your hood so cant tell you what is there.
as you can see computers are not a toaster or desk lamp.
