I have fixed and attempted to fix many laptops.Īt this point, unless you see something simple and easy (open surface-mount fuse, failed surface mount diode, broken component), a new motherboard is what you need, provided the laptop is worth it. Some sections vaguely similar with 820-00034.Then the power is not reaching the mobo. Some sections near I/O ports vaguely similar with 820-3588. As of bvr and sch available on Badcaps forum. XinZhiZao may have boardview.As of bvr and sch available on Badcaps forum. Use 820-01041, GPU area will be different (no VRAM on 820-01827).Īs of bvr and sch available on Badcaps forum. A modified boardview in bvr format does.Īuthenticity of boardview unconfirmed (file is identical to 820-01041). Original boardview in brd format does not have the correct board outline.
Power sequence diagram also available with board number 820-01055. Use 820-01041 boardview and schematic, 820-01326 unavailable, only difference is Vega GPU as far as i know Use 820-00281 some differences around CD3215 at least. Use 820-00239, may have differences around CD3215. Correct boardview is available in XinZhiZao. Use 820-00875 which does not have the PI3USB32224BXEAE near USB-C ports and different populated parts for SSD_BOOT_L/SSD_PWR_EN_L (see A1708 SSD). Available schematics does not have the correct part either.Īuthenticity unconfirmed, very similar to 820-00244. Touchpad connector has wrong pinout in schematics, refer to 820-00163 again. Correct boardview is available in XinZhiZao, otherwise use 820-00163 (touchpad, SPI ROM…) and 820-3662 boardviews depending on the area. Warning: most boardviews distributed as 820-00138 are in fact 820-3662. Correct boardview is available in XinZhiZao, otherwise use 820-3536. Warning: most files distributed as 820-3476 are in fact 820-3536 (4GB RAM variant, 8 RAM ICs instead of 16).
