I have a dell laptop and it was working fine. Recently i started facing some problem with the adapter. The adapter is not responding now. The adapter is not charging the battery and also it is not showing the light that it used to show during charging. Now the adapter is gone and i want to run the laptop urgently. As i have some urgent work related to laptop. My cousin has a hp laptop and i am thinking that whether i can use the adapter of hp to charge my dell laptop. I checked the voltage power of dell it measures 4.5V while the hp measures 4V. So will these voltage difference lead to some complication if i charge the laptop with the hp adapter. Suggest me some methods or modifications to the laptop to enable charging.
