Question

Asus ROG g75vw has trouble turning on :(

Jul 2, 2016 12:29PM PDT

Recently my laptop has had trouble turning on. Whenever I press the power button, the LEDs flash on but cuts off about a second later. This process repeatedly continues until it finally turns on. I have to keep the laptop plugged in order for it to turn on, and it takes about 15 minutes. Once the laptop is on, it is fully functional that I am aware of. Please help!

Get estimates.
Jul 2, 2016 12:52PM PDT

I see this came out in 2012 so it's on par with the usual time before you see the need to repair. The hard to turn on can have many causes but get estimates as I see them for just under 500 at Amazon.

Okay

Could you please go into more details as I do not completely understand. Thanks!

What part needs more detail?
Jul 2, 2016 4:02PM PDT

The problem that hard starting could be quite a few parts?
Or why you want an estimate since you can get a working one for just under 500?

Why I think getting a working one is an option is that you could slide your HDD over and start where you left off and have spare parts for another failure.

Here a repair runs about 150 plus parts. A motherboard can be 300 so getting a working laptop is cheaper.

I think I understand

This laptop works fine! The only problem is that it has trouble turning on and a few other minor problems but it is fully functional. I don't really need a "working" laptop, I just would like to get this one fixed as it is very expensive.

Then it needs to be seen on a test bench.

They'll try a few things and replace what fixes it. My first thought is a failing motherboard or a dying CMOS battery.

There are folk that won't replace the battery without a test so we do that for half price and then wait for them to give the OK. That's 85 bucks! Makes you wonder why they don't try the cheap parts first. Actually I don't wonder. There are some clients that demand you test, call and then repair.

Why do you think that it could be the cmos battery? Sorry I am not trying to be rude, I was just wondering.

Test the CMOS battery with a volt meter.

If under 3 volts replace. It's cheap.

Remember what I wrote above?
Jul 2, 2016 5:42PM PDT

There are folk that will question every diagnosis. This is why for those folk only a shop counter or bench will do.

It's a common issue and for under 5 bucks you can see if it helps. Again, there are clients and we do love them that insist we measure the battery, tell them the findings and then change. We love them because it's easy work with fantastic margins.

No where an I saying this is it. Just it's one of the things it can be and you could, for little money take the gamble.

If not, a shop will do this for you but it is pricey. Here the shop down the street is 150 min shop counter fee and 5 bucks for the battery!

Not a picky one
Jul 2, 2016 6:05PM PDT

Oh yes, I am definitely not one of those people who want to try everything. If possible, I would like the cheapest solution because I do not have much money to manage with. And I will try and test the CMOS battery, thanks for the input!

It's just an educated guess.
Jul 2, 2016 6:22PM PDT

It is not for sure but for the 5 bucks (we buy in bulk and it's much less for the common CR2032s) it's something I would never pass up.

I have had a few folk that come back all mad that it wasn't it. I never said it was. I wrote it could be.

Check your model for the battery type.
https://www.amazon.com/Energizer-2032-Battery-CR2032-Lithium/dp/B0042A9UXC is under 1 buck each.

CMOS battery type
Jul 3, 2016 8:50AM PDT

I could not find the type of battery online but I will definitely take a look at it once I am with my laptop. Please stay tuned and thanks for your help!

Another thread.

https://www.reddit.com/r/techsupport/comments/2rasbv/urgent_asus_g75vw_wont_boot_up_xpost_from/ has a non working same model and they can't bring themselves to replace it.

What are the odds?

Found the CMOS battery at the 4 minute mark of https://www.youtube.com/watch?v=otysJ5C9foI

It's one of those other type CMOS battery so order it from Asus parts. Most owners would not be able to do this work.

There are prior discussions about resetting the bios settings so I think you would have found those by now.

Replacing the CMOS
Jul 3, 2016 12:25PM PDT

I have had some experience with computers so I will attempt to take the laptop apart myself. I just hope I dont break anything. Fingers crossed! I'm not exactly sure what type of cmos I need to get or if I even need to get it, but I will see once I open it up. Thanks for your help!

See my prior reply. It shows the battery.
Jul 3, 2016 1:05PM PDT

And it's the model that I just order up from Asus parts. We don't usually wait to get inside on that model since the laptop would sit in the shop for weeks with the owner getting more impatient by the day.

call the service center
Jul 8, 2016 5:26AM PDT

I've seen similar issues like this with the mal-connection to the battery or panel hinge. Calling ASUS service center or your local authorized fixing store could be a better solution.

cmos battery
Jul 10, 2016 5:52PM PDT

i have now found out that it is indeed the cmos battery that is the issue. the only problem is that the g75vw so old that i cannot find a replacement for it. does anyone have any ideas?

Any good tech
Jul 10, 2016 6:00PM PDT

Can clip the wires and make a new one. The video I saw looked just like other 2 pin CMOS batteries so the tech would look at the voltage and then clip the old and new leads to make a new battery pack.

This is trivial work. But I find many shops will not do such today.
