Seagate Portable external hard drive 1TB USB 3.00 not detected when connected to Laptop

[vniyer09]

Led light in Seagate Portable external hard drive 1TB USB 3.00 glows when connected to Laptop Lenovo Yoga 500 but not detected when I open "This PC". This is followed by a peculiar sound indicating that this drive is connected. I have Windows 10 64 bit operating system installed in Laptop. Previously (before windows 10 update), the expansion drive icon was visible when I open "This PC" and I could view all files and folders and also add or delete the same. Again I connected my external Seagate portable hard drive to another Laptop (HP) where no Windows 10 update is done and to my surprise I found this laptop easily detected the hard drive when I opened "This PC". I do not know what has happened after Windows 10 update? Have they deleted or overwritten some software whereby detection of external drive is not possible ? I dn't know. Could anyone from Microsoft windows help me? -

Maybe your laptop doesn't provide enough power.

If it's not getting enough power through the laptop's USB port you'll have to buy a mains-powered USB hub to plug the drive in to - - that should fix the problem.
