ʻAʻohe mea aʻu e hoʻohana ai, loaʻa iaʻu kahi hewa "Display connection limit", "Charging limit" error, hoʻokahi wale nō o nā pale ʻelua e hana, a ʻaʻole e hoʻopili ʻia i ka dock. He haunaele.
Pono e hana hou ʻia nā firmware ma ka motherboard, docking station, a pono e hōʻano hou ʻia nā mea hoʻokele. Ua hana hope loa ia i ka hana ʻino. ʻO ka USB-C kahi maʻi poʻo.
Hoʻohana au i nā kikowaena docking non-Dell a hele mālie nā mea a pau! =D ʻAʻole paʻakikī ka hana ʻana i kahi pahu USB-C maikaʻi - hana maikaʻi lākou a hiki i ka wā e holo ai ʻoe i nā mea ʻē aʻe o Thunderbolt, a laila aia nā pilikia ma ke aupuni "plug, unplug, work". ʻAʻole wau e wahaheʻe, i kēia manawa makemake wau e ʻike i kahi schematic o kahi motherboard no kahi pona Dell me kēia mau kikowaena docking.
Ua pololei ʻo Arya. Ua nalowale nā pilikia a pau i koʻu kūʻai ʻana i kahi mea hoʻokaʻawale uila USB-C mai Amazon. Hiki ke hoʻopili ʻia nā kīʻaha, webcams, USB dongle, hoʻopili ka monitor i ke awa USB-C, HDMI, a i ʻole DP ma ka kamepiula, a ua mākaukau e hele. Ua haʻi ʻia iaʻu i ka mea e hana ai e kahi kanaka IT nāna i ʻōlelo ʻaʻole pono ke kālā ʻo Dell dock.
ʻAʻole, ʻo Dell idiots wale nō kēia - ʻoiai ua hoʻoholo lākou e hana i ka huahana me ka USB-C i ka wā e hoʻohana ai i ka mea hoʻohui like.
ʻAe, inā ʻoe e nīnau mai iaʻu, pono e ʻoi aku ka kikoʻī o kahi hāmeʻa e like me ka papa e pili ana i "no ke aha ʻaʻole i hoʻopiha piha ʻia". ʻO ka memo pop-up "Ma ka liʻiliʻi loa 9V @ 3A USB-C charger pono" e hoʻoponopono i nā pilikia o ka poʻe e like me kēia a hana pololei i ka mea i manaʻo ʻia e ka mea hana papa. Eia nō naʻe, ʻaʻole hiki iā mākou ke manaʻoʻiʻo e hoʻokuʻu kekahi o lākou i hoʻokahi firmware hou ma hope o ke kūʻai aku ʻana o ke kelepona.
ʻAʻole wale ka maʻalahi, akā ʻoi aku ka ikaika. ʻEhia mau mea hoʻohui USB nahai āu i ʻike ai ma nā polokalamu like ʻole? Hana pinepine au i kēia - a ʻo ka mea maʻamau e hoʻolei ʻia kēlā ʻano mea, no ka mea ʻaʻole hiki ke hoʻoponopono ʻia ...
ʻO nā mea hoʻohui USB, e hoʻomaka ana me ka micro USB, ua palupalu loa, a me ka hoʻopili mau ʻana a wehe iā lākou, maʻamau e ka poʻe ʻaʻole i hoʻonohonoho pono iā lākou, e hoʻohana i ka ikaika nui, e wiliwili iā lākou mai kēlā ʻaoʻao a i kēia ʻaoʻao, e weliweli nā mea hoʻohui. No ka ʻikepili, hiki ke ʻae ʻia kēia, akā hāʻawi ʻia ua hoʻohana ʻia ʻo USB-C i kēia manawa e hoʻohana i nā mea āpau mai nā wati akamai a i nā kamepiula holoʻokoʻa a me nā ʻano hāmeʻa uila āpau ʻaʻole i hoʻohana i ka ʻikepili, e lilo nā mea hoʻopili pōʻino i mea maʻamau. . ʻOi aku ka hopohopo iā mākou - a no ke kumu maikaʻi ʻole.
Pololei, ua ʻike wale au i hoʻokahi mea hoʻohui pahu i haki ʻia a he maʻalahi loa ia e hoʻoponopono (ma waho aʻe o ka mana Dell BS, hana wale ia ma kahi loina ponoʻī hiki ke kamaʻilio pū me ia, he palupalu maikaʻi, hiki iā ʻoe ke hōʻino iā ia inā inā paha. ʻAʻole ʻoe e holo kaʻa kaʻa..) ʻOiai no ka mea hoʻoponopono ʻike, ʻo ka mea hoʻohui USB-C ʻo PITA, me nā wahi PCB hou aku, nā pine solder liʻiliʻi ...
Hoʻohālikelike ʻia nā mea hoʻohui barrel no ka hapalua pōʻai (a i ʻole ka liʻiliʻi) o nā mea hoʻohui USB-C maʻamau. ʻO kēia ke kumu no ka hoʻololi ʻana o ka pine kikowaena i kēlā me kēia manawa i hoʻokomo ʻia, a me ka USB, ʻoi aku ka pōkole o ka lima lever. Ua ʻike au i nā pahu pahu he nui i hoʻopōʻino ʻia e ka hoʻohana ʻana.
ʻO kekahi o nā kumu i ʻike ʻole ʻia ai ʻo USB-C he mau mea hoʻohui a i ʻole kelepona. Inā ʻike ʻoe i kahi huahana i ʻike ʻia i ka "hue" a i ʻole "ʻoi aku ka ʻoluʻolu" me ka hoʻoheheʻe ʻia ʻana a i ʻole nā mea ʻē aʻe, he palaka paha ia. Loaʻa wale mai nā mea hana kelepona nui me nā kikoʻī a me nā kiʻi.
ʻO ke kumu ʻē aʻe ke hoʻohana nei ʻoe i ka USB-C ma mua o nā mea hoʻohui i ka pahu. Hoʻopili a wehe nā kelepona i kēlā me kēia lā, i kekahi manawa he mau manawa.
