STUDIO 1557 WON'T POWER UP
STUDIO 1557 WONT POWER UP WHEN PLUGGED IN EITHER WITH OR WITHOUT BATTERY. AC POWER SUPPLY WORKS FINE AND IS LESS THAN 1YR OLD. CHARGES AND RUNS my LATTITUDE JUST FINE. laptop was purchased in summer or 2011, BATTERY IS ORIGINAL . LAST HARDWARE/ BATTERY DIAGNOSIS WAS 8-15-17. HERES RESULTS: 1. Designed capacity 66 2. Current charge 100% 3. Current charge 3.43 Wh 4. Full charge capacity 3.43Wh 5. Designed capacity 5.20Wh. I dont know what Wh stands for, but 3.43 is 66% of 5.2. I do know basic math. To make a long story boring(LOL), my ?'s are 1. Will this laptop power up and operate with a bad or failed battery?. 2. Will it power up and run with no battery?( I have never tried this) 3.is it most likely the battery is the problem, if not what would it be? power button? Main board? oh one last thing , i keep it plugged in 24/7 and operating 12-18 hrs a day. main components: I7 processor, 8gb ram, 1tb hard drive. please help and thank you.my user name contains service tag #

Remove the battery - if the system will power up on AC only, the battery is bad. If it won't, the mainboard is bad.

No, that's not possible. From your description, the board is toast.

is it possible to jump directly into the proper board teriminals(2,) + and -- where the batterie normanly connects and power it up directly fron ac adapter . say cut the connectot off and plug into board. notice the burn marks on the ac plug where it goes into the board. is the board friednor just at that terminal plug? i orderd=ede an new plug , power button/board and a battery. did i waste my money.
