Re: Help with Gigabyte GA-RP55W5 Rev 1.1 motherboard troubleshooting

This morning on tested it out with the multimeter. At first it wouldnt shut down while the battery was disconnected so I reconnected the battery and tested it. While the laptop was charging and working as normal the voltage on the DC jack was 19.48v when it switched to battery the voltage went up to 19.56v. I also measured the voltage at the 8 pin connector and the reading were the same.

Later I disconnected the battery and tried again, while the laptop was running the voltage was 19.48v and just before...

Re: Help with Gigabyte GA-RP55W5 Rev 1.1 motherboard troubleshooting

Ill give it a go tomorrow morning, when you say the big copper circles. Do they look like where the screws go? Also will the DC jack housing be ok for grounding? One last question, in the pic of the DC jack board there three solders points is there anyway to tell which is the pos and which is the neg? I could ground on the solder point.

Ive had a look for the charger online. I would be paying around $70 in Australia. Just to try it out, it may not be worth it.
Thanks for the advice

Re: Help with Gigabyte GA-RP55W5 Rev 1.1 motherboard troubleshooting

Ok, this is what i will do tomorrow morning.

Connect the AC to the laptop and power on the AC and the laptop. Ill touch the black probe of the multimeter to the DC jack houseing (which is metal) then the red probe ill touch each of the three solder connects of the DC jack separately to find the power. I need to get a reading for both when the AC is charging and when it cuts out. Then test the other end of the DC jack board, where the 8 pin cable connects. Again find the power but touching each point....

What do you mean did it charge offline?. If the laptop is turned off the charger would work fine and would continue charging if it's turned on then it would switch between battery and charger. This morning I opened up the AC adaptor but unfortunately I cannot see the circuitry because it is covered by a yellow foam like substance the yellow foam would have to be removed to expose the components on the circuit board. Did you read the article in the link which I posted which somebody else has the same problem and...

Re: Help with Gigabyte GA-RP55W5 Rev 1.1 motherboard troubleshooting

Well, this is what has happened. This morning i set out to try Ubuntu Live USB on it but first i tried the laptop in Windows to make sure it was still playing up. Well, it didnt do it so I started up a game which will always make it switch between AC and battery, except for this time. I used the laptop for about half an hour and it just did not do it. I tried again in the afternoon and again it ran flawlessly.

This problem seems to be common, read this

Re: Help with motherboard troubleshooting

Thanks WayofTheRoad for your response. Ive tried all those suggestions recently. If I disconnect the battery then when the AC cuts out the laptop dies because theres no battery connected. The laptop will work with only the battery connected. I have also tried uninstalling the battery driver and also running Troubleshooting on power, it didnt find anything.

Another thing which i tried the other day was to run the laptop using a Linux Live USB. the plan was to run a program called Stress to push the CPU and to try to get the...

Hi Guys and Girls
My first post. I have a Gigabyte gaming laptop. Its a P55Wv5. Over the past few years its developed a problem with what i believe is a power issue. The motherboard model is GA-RP55W5 Rev 1.1

When using the laptop on mains power, every few seconds it cuts off from mains and runs on battery then switches back to mains.

Ive tested the AC adapter and im getting 19.9v which is constant. Ive tested the 8 pin cable which connects from the DC jack board to the motherboard. Both the AC adapter and the cable seem to be fine.

The next...

Hi guys and girls
I run a small PC repair business from home, mainly software issues. Im looking at getting into the electronics side of this eg motherboard repairs. Ive never done this before. Recently my gaming laptop started playing up so ive done a fair bit of troubleshooting on the software side, now im thinking its more hardware rather than software. After chatting with Gigabyte, and describing the problem to them, they thought the best solution was to replace the motherboard at a cost of $1200. I think now is a great...
