G74sx - Charger disconnecting, reconnecting

[Yisera]

Hello. I have this problem on my g74sx which is about 3 years old now. Whenever I'm playing, maybe the laptop gets too hot or the charger does and the laptop begins to disconnect/reconnect the charger. This has been happening for a few days now and I'm afraid it might mean it's time to replace the laptop.

I think it's safe to mention that I have 2 chargers atm, both of them are bought in amazon since the original charger died a year ago. Both chargers present the same problem, so I can safely say it's definitely not a charger problem. Could it be the charging center or loading center of the computer? Is there an easy way to verify this? I also tried changing the Mickey Mouse like Power Cord, same problem.

Any comments will be much helpful.

hmmmmm... interesting....

Have you logged the sensors using HWiNFO64 ? I would check and see if it always happens at the same peak values for temps and voltages/wattage

Also if the charging port pins solder has cracked, when it becomes warm and the pin ports expand it could explain the intermittent connection lost...

I downloaded HWiNFO64, what do I do now?

EDIT
I run it with default settings and this warning showed:




What does this mean?

Just choose "disable this sensor" then log your temps and voltages. If you don't disable the sensor it could cause your cpu usage among other things to go up. Disabling it in HWINFO isn't going to hurt anything.

Thanks! Will post the log after tonight's gaming with friends (World of Warcraft). FYI I just started the logging under air conditioner, and the charger already started connecting/reconnecting. Hopefully this software can show what's wrong.

This is what I see so far. Are those temperatures normal? Keep in mind that I'm logging this in the office right now, where the temperature here is 16 degrees celcius.


This is the log for 1 hour, found in the attachment section. Please can anyone tell me what can I do?
