Laptop charges only tipped on side?
About ten days ago, my 1-year-old HP Pavilion G7-2017 laptop stopped charging when plugged to the AC adapter. I've googled this issue a bunch and have only come up with wobbly power seats, battery issues, or with people who have finicky adapters that have to be moved to get a charge. None of these are applicable to my situation.
Currently, my laptop (not the charger) has to be moved or tipped to get a charge from the old AC adapter but runs great on battery power once charged and, if stood on its side, will connect to the power supply without the battery installed. Moving the laptop breaks the power connection, though, and shuts the computer down if the battery is not in it.
In fussing with it, I discovered it would work when either:
A) it was tilted totally on its left side (dc connector is on the right side, so cord would then stick out the 'top')
B) slight pressure was put on the underside just in front of the battery where the RAM is located.
Finally, it stopped registering the AC adapter with either the orange or white LED and I couldn't get it charged so I did the next logical thing and took the whole thing apart. I thought because of the nature of how it was charging and finicky it might be a loose connection to the power supply internally. I took everything in the laptop out and double checked all the connections on power, motherboard, etc -- nothing is amiss. The power cord slot inside is secure and functioning, RAM is seated correctly, etc.
Put it all back together and still couldn't get it to charge so I took it to Best Buy to borrow an appropriate AC Adapter today. This is what happened:
1. With the battery in, I plugged in new power cord while laptop was sitting neatly on the countertop (not tilted) and it immediately registered with an orange LED light at the point of entry for the power connection without having to manipulate or tip the laptop, which is what I had to do with the old adapter, ergo I thought AHA! It MUST be the AC Adapter!
2. Started it up and got three long beeps. Checked BIOS records for HP Pavilion G7 2017 and learned it could be hardware related.
3. Replaced the original 4GB RAM with borrowed Geek Squad matching test RAM and tried to power again.
4. Success! New RAM and borrowed adapter did the trick, assumed it must be RAM issue.
5. Bought replacement 4gb RAM stick, installed, rebooted to double check while it was plugged into borrowed AC Adapter -- everything booted fine.
6. Got home and plugged in my old AC adapter but no orange LED to tell me it was registering.
7. Tipped laptop on its side and voila! New RAM plus Old AC Adapter still had to be tilted on its side.
8. Put old RAM back in and tried again; same result -- old AC adapter only registers in the power connection when the laptop is placed on the left side with cord sticking out the 'top' or when lightly pressed on the underside of the center of the laptop, though this latter is incredibly finicky.
The fact that a borrowed adapter worked fine but this old adapter only works when the laptop is tilted is what keeps me thinking it's AC Adapter itself but could still be a connection issue or other hardware issue. Am I totally off base? For what it's worth, I've ordered a new AC adapter to try it out again.
Any thoughts out there?
