Answer to: The laptop not on and not chargeIf there is no charging lite, its eater the charger, or the notebook. The charger is the easiest to start with, if it is faulty then you have your answer, if it's powered up then its the notebook. Can be as easy as a faulty notebook plug, the battery or the motherboard, Seek pro help unless you have the skills necessary to do the full job.
Answer to: availability of hp 657503-001 battery as of nov. 2016The battery has 6 li-ion pouch cells, NO 18650 Cans in the battery pack. Good thing is the pouch cells are: 3.7v, 14.7Wh .... Commonly available. THE REALLY GOOD THING IS .... I bought a proper HP Smart Charger (19.5v 150W 7.7A) for my HP ENVY 17-3090NR 3D and I have slowly nursed the battery back to 100% by quickly unplugging, then plugging back in (notebook side). JUST as the plug disappears on the icon, plug it back in. On the HP Smart Charger, notebook side, the center pin is 19.5v the inside barrel is 19.5v, the outside is negative. All other chargers I have tested are 6.5v on the pin, 19.5v on the inside of the barrel.

You can have a higher capacity charger than specified, but YOU CANT GO LOWER! The 2 *NEW* chargers I bought are from DrLappy, who is a computer service and retail group. They dispose of older *GE...
Answer to: availability of hp 657503-001 battery as of nov. 2016EDIT: There are no 18650 cans in the battery pack. There are 6x pouch packs. If you want proper charging, check the charger, it was at fault for me. You must get the HP Smart Charger, it has power on the pin and inside of the connector (The outside is negative). See bottom post by me. ____________________________________________________________________________________________ It's my turn looking for a battery for my HP ENVY 17-3090NR 3D. I'm going to have it cracked open and rebuilt locally. Chances are it's a bunch of 18650's in there, it shouldn't be much of a problem, can even upgrade to a Sanyo NCR 18650GA cell. The Battery Management System is generally the fault of a battery pack, it appears from the lead wires that the balancing is done on the MoBo, so a defective BMS shouldn't be the issue, I have no problems with my MoBo. Ya, just 1 year past the last manufacturing run date its obsolete, parts from secondary markets aren't even stocked.......
