It fits the detachable keyboard base unit — not the tablet itself. Compatible with Slatebook x2 10-H010NR and TPN-Q127 variants, among others.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDock-specific fitment:\u003c\/strong\u003e\n    The Slatebook x2 splits power between the tablet and keyboard dock. These models share the MY02XL form factor — same 7.4V rail, same flat Li-Polymer footprint, and the same BMS handshake that reports charge state back to the host OS when the tablet is docked.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on a Slatebook x2 dock. The BMS communicated charge state to the OS without error flags, and the protection circuit engaged correctly at low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration for the dock battery:\u003c\/strong\u003e\n    After fitting this cell, let the dock discharge fully to hibernate cutoff, then charge uninterrupted to 100%. This resets the fuel gauge IC against the new cell and clears the inaccurate health warning that typically appears after a cell swap on HP hybrid systems.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Slatebook x2 dock shows 0% or \"unknown battery\" after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe EEPROM on the old cell stores cycle count and health data the OS reads directly. A new cell has a blank or mismatched EEPROM, so Windows reports 0% or flags the battery as unknown. This is a firmware calibration gap, not a fault with the replacement cell. Running one full discharge-to-cutoff cycle followed by an uninterrupted charge to 100% lets the fuel gauge IC write a fresh baseline against the new cell. After two or three cycles, the reported percentage stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDock charge stops at 80% and won't climb higher\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eHP's battery management firmware on the Slatebook x2 includes a charge threshold that caps at 80% when battery health is flagged as degraded or unrecognised. The BIOS reads the old EEPROM health data and applies the limit to protect what it thinks is a worn cell. Enter the BIOS setup utility, navigate to Power Management, and disable the Battery Care Function or charge limit if present. If the option is greyed out, run the calibration cycle first — once the fuel gauge IC registers a full cycle, the BIOS usually releases the cap and charges to 4.2V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409773658202,"sku":"BWCS-HPS210NB-1","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409773690970,"sku":"BWCS-HPS210NB-2","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409773723738,"sku":"BWCS-HPS210NB-3","price":68.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPS210NB-1.webp?v=1779580839","url":"https:\/\/batteryweb.com\/products\/hp-slatebook-x2-replacement-battery-74v-2830mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
