Hello friends today we are learn laptop repair if our laptops USB port not work then how to repair and solved it .its very easy so watch the complete video and learn how to repair it.
You are overloading the 5v regulator output taken from the contact point on the motherboard. This approach may or may not work in all cases. Each USB port has 500 mA current drawing capacity. You are bypassing the designed current source on the motherboard. Better way is to replace the 5V regulator chip used for providing USB power or provide an alternative 5V 2A power to USB ports.
Agar kabhi apne apna laptop local servicing ya repair ke liye diya tha, aur uske baad se ya pahle se hi usb port ki pareshani samne ayi hai toh khud laptop ke motherboard ki" notch wali wiring jo ek usb port ke liye di jati hai use chek kare. Mere case mein mere laptop ka kam thik se meine hi ghar par kiya, shayad aap ke laptop ki bhi yahi mamuli si pareshani ho....
Mere pass hp ka leptop he i3 Charo port me external keyboard mouse and pendrive connect hi ni ho rhe he External mouse me light tho blink hoti he pr arrow move ni hota he Kya problem hogi sir? Repairing wala bol rha he pura motherboard change krna pdega
Keyboard disconnect karke dekho,agar keyboard lagane se problem ho raha hai to.halaki aisa hona to nahi chahiye.(usb driver proper dal ke dekho ya fir)
Use model ka schematic dekho net me or usb ic ko check kare ya fir usb ka track ko dekho data in data out ka track par resistance cut jata hai kai bar.
Sir, first of all you should reinstall the WiFi driver of the laptop, still it does not come, then clean the WiFi card properly, even if it does not come, then take a USB WiFi receiver from the market and you will get around 250.
Agar koi bhi nahi chal Raha hai to pahle proper driver install kare. Agar lagta hai hardware ka problem hai tab check karna hoga problem ke anusar solution hota hai dost.
Mery laptop ki window 8.1 pro deactivate ho gye hai active krny k lia key man rha hai system key mery pas hai ni or ports mai bht zang lg gya hai 3sra speakr jal gya hai mgr laptop bilkol new hai khulwana ni chahta mai
Mere laptop k usb port ( jo kharab hai) me 4 volt dikha raha hai par jaise hi usme mouse ya koi bhi device insert karo immediately voltage drop karke 0 ho ja raha hai. Aisa ku?
@@Technicalbaba01 nahi usb port me koi physical damage nahi hai. Alag se usb hub lagane pe bhi usme 4 volt aa raha hai but jaise hi kuch bhi insert karta hu aur uske baad check karta hu to 0 voltage aane lagta. Aisa lag raha jaise koi condenser hai jo 4 volt de raha hai. But load lete hi immediately discharge ho ja raha aur 0 dikhane lag raha. Device hatate hi slowly fir se 4 vol ho ja raha
@@Technicalbaba01 thank you. 3 me se 2 USB port kharab hai. Fir mai soch raha hu ek usb hub khareed lu 200 ka aur jo ek usb kaam kar raha hai usime laga k kam chala lu. Kya sahi rahega?
Agar 3.0 port hai to drivers download karke chalao pahle usb port blue color ka hai kya dekho blue hoga to 3.0 hai jo model hai or jo operating hai uska usb 3.0 download karo .run karo ho jayga .phle yahi karo
Jo port kam nahi kar raha o 3.0 hai kya, Device manager me jake dekho uska driver me yellow ka ?marks laga hai kya, Agar drivers ok hai to hardware ka problem hai laptop open karke check karo jaise video me hai waise.
