It replaces OEM part numbers HSTNN-UB0G, HSTNN-UB0F, HSTNN-DB0G, and GC06, among others. If your original cell no longer holds a charge or the BIOS flags battery health as poor, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMini 5101 compatibility across variants:\u003c\/strong\u003e\n    The FM956UT, FM955UT, FM978UT, and 24 additional Mini 5101 configurations all use the same battery bay geometry, connector pinout, and 10.8V rail — one cell fits every variant on the compatibility list.\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 on the Mini 5101 platform. The BMS communicated correctly with the EC, accepted a full charge without false cutoff, and reported capacity within normal variance on the fuel gauge IC.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install calibration on the Mini 5101:\u003c\/strong\u003e\n    After fitting, run the battery down to hibernate cutoff, then charge uninterrupted to 100%. This triggers the BIOS battery learn cycle, clears the inaccurate health warning that appears after every cell swap, and gives the fuel gauge IC a reference point against the new cell's actual chemistry.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP Mini 5101 BIOS reads health data from EEPROM registers that the old cell wrote over hundreds of cycles. A brand-new cell arrives with different EEPROM state, so the BIOS flags it as degraded before a single cycle has run. This is not a fault with the replacement — it is a stale data mismatch. One full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS to rewrite those registers against the new cell. After two to three cycles, the health indicator normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNetbook shutting down at 20–30% charge shown on the gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's voltage curve. The gauge displays a percentage based on the old cell's discharge profile, so it reads 25% while the actual cell voltage has already dropped below the EC's cutoff threshold. The fix is the same calibration cycle: discharge fully to hibernate, charge to 100% without interruption, and repeat once more. After two full cycles the gauge tracks the new cell accurately and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410811846746,"sku":"BWCS-HPM510HB-1","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410811879514,"sku":"BWCS-HPM510HB-2","price":139.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410811912282,"sku":"BWCS-HPM510HB-3","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPM510HB-1.webp?v=1779581157","url":"https:\/\/batteryweb.com\/products\/hp-mini-5101-replacement-battery-108v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
