It slots into the same bay as the original cell and connects via the factory harness. No hardware modification needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eENP 630 \/ ENP 680 platform fit:\u003c\/strong\u003e\n    These models share the same 11.1V three-cell Li-ion architecture, identical bay dimensions (205.40 × 54.29 × 20.20mm), and the same connector pinout — so one replacement cell covers the full ENP series listed above without adapter cables or modified firmware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the ENP platform. The BMS engaged protection at the correct low-voltage cutoff and the charge controller accepted a full charge without triggering overcurrent faults.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eENP series BIOS learn cycle:\u003c\/strong\u003e\n    After installing this cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears on the first boot after any cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ENP 630 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on these laptops stores discharge curve data from the previous cell in EEPROM. When a new cell goes in, the IC reads that old curve and miscalculates the actual remaining charge. Under full CPU and display load, the voltage drops below what the old curve predicts at 20–30%, and the system interprets it as a safe-shutdown threshold. Running two full calibration cycles — discharge to hibernate, charge to 100%, repeat — lets the IC relearn the new cell's actual curve and pushes the cutoff point back to the true low-voltage floor near 9V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting 0% or \"unknown\" battery immediately after fitting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the ENP platform reads battery identity data from the EEPROM on the original pack, and a fresh replacement cell has a different EEPROM signature. The BIOS flags it as unrecognised and displays 0% or a health warning rather than live charge data. Boot into the OS and let the battery manager run — most ENP BIOS versions will accept the new cell after one full charge cycle and begin reporting correctly. If the 0% reading persists after a full charge, enter BIOS setup, navigate to the power or battery section, and run the battery reset or recalibration option if present.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410848972890,"sku":"BWCS-AUF3NB-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410849005658,"sku":"BWCS-AUF3NB-2","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410849038426,"sku":"BWCS-AUF3NB-3","price":95.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUF3NB-1.webp?v=1779581357","url":"https:\/\/batteryweb.com\/products\/pc-club-enpower-enp-630-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
