Pom cov ntawv tshaj tawm ntawm Reddit ntawm ib tus neeg hloov pauv nws T450s los siv USB-C them chaw nres nkoj hloov chaw ntawm qhov qub. Kuv txiav txim siab ua li ntawd ib yam.
Koj tuaj yeem ua qhov qub nrog T440, T440s thiab T450 txij li lawv txhua tus sib koom them tib lub cable/chaw nres nkoj yam.
Koj tuaj yeem nyeem thawj kab ntawv ntawm no:
Kauj ruam 1: Mus kav khw
Rau qhov no koj yuav xav tau:
- USB-C PD 20v txhais. Koj tuaj yeem pom cov no ntawm Aliexpress rau qhov pheej yig dua. Qhov kuv tab tom siv tsuas yog siv lub zog siab tshaj ntawm 65w.
- 280 ohm resistor. Kuv tsis tuaj yeem pom ib qho hauv kuv lub tebchaws yog li kuv siv 270 ohm ib qho, uas ua haujlwm tau zoo
- 3D luam bracket. Koj tuaj yeem siv ib qho hauv thawj daim ntawv lossis siv kuv li. Kuv cov ntawv tuaj yeem luam tau yooj yim dua ib qho los ntawm Reddit. Txuas:
- Cov ntsia hlau, qhov chaw nres tsheb soldering, tin,…
Qhov laj thawj rau qhov kev tawm tsam no yog rau koj ThinkPad kom nkag siab lub charger kom raug. 280 ohm yuav yog 65w them nyiaj, yog tias koj muaj 90W square charger koj yuav xav tau 540 ohm resistor thiab tseem muaj cov nti sib txawv.
ThinkWiki twb tau ua qhov chaw tsis txaus ntseeg txog teeb liab tus pin thiab tsim nyog tus nqi tiv thaiv ntawm no, nqes mus rau lub teeb liab ntu ntu:
Yog tias koj txhawj xeeb txog kev tua koj lub khoos phis tawj koj tsuas tuaj yeem xaj lwm qhov chaw nres nkoj/txuas cov khoom thiab ua haujlwm nrog qhov ntawd.
Kauj Ruam 2: Kuaj thiab Txhuam
Qhib lub khoos phis tawj, tshem cov ntsia hlau me me tuav qhov chaw nres nkoj uas twb muaj lawm, thiab txiav cov hlua txuas ib sab ntawm qhov chaw nres nkoj. Yog tias koj txhawj xeeb txog kev tua koj lub khoos phis tawj koj tsuas tuaj yeem xaj lwm qhov chaw nres nkoj/txuas cov khoom thiab ua haujlwm nrog qhov ntawd.
Koj yuav tsum sab laug nrog 5 xaim: 2 liab, 2 dub, thiab 1 dawb. Solder 2 lub xov tooj liab rau + sab ntawm lub usb txuas txuas. Muab cov 2 dub tso rau sab - sab. Solder tus tiv thaiv rau cov xaim dawb thiab tom qab ntawd mus rau - sab ntawm usb nti.
Txiav lub nti rau hauv qhov khoo thiab ntswj cov khoom rov qab.
(yog lawm kuv tub nkeeg heev yog li kuv tau theej los ntawm Reddit)
Kauj ruam 3: Tadaaaaa
Yooj yim nws ua tiav!
Rov ua dua koj lub ThinkPad thiab ntsaws lub charger rau hauv.
Kuv siv Xiaomi 65w PD Charger btw.
Tom qab ntsaws rau li 2 teev, lub cable tsis tau kub thiab lub charger tsuas yog sov me ntsis.
Yog li, SUCCESS !!!
