GT72-6QD Battery [Solved]

Hi, so my system is 4 years old and it's looking like I need a new battery.

Even though HWInfo states a 1.9% wear, there is no way a battery can drain 747.0w on a 83.5wh battery (Original one that come with the system).

However basically the symptoms are.

Battery lasts less then 30 minutes

Battery calibration will drain to 83% and the system shuts off

Windows keeps reporting about Kernel Power Source Event ID 105 (AKA power switching from AC to Battery and back)

So unsure what the issue is, part of me says battery however could be PSU or even the jack.

Also trying to find decent battery replacement in UK too if anyone has ideas let me know.

Also if there is any other test to try please let me know.

UPDATE: so I disconnected the battery and put load whilst it was just AC, it promptly shut down.

CPU temps was 67c and GPU temps was 69c

However Prochot showed in Throttle stop Red then Yellow then system died.


Update 2: Nothing is working now not even powering on.

Update 3: I now have the laptop booted again, I have replaced the GPU to its stock GTX 970m 6GB (Thankfully i still had the card).

It still refused to boot for a while but then it booted, noticed one fan stopped working unplugged it a few times and now its spinning again.

I am now at a total loss on what the issue is, it was even refusing to detect the charger too. I know the laptop is 4 years old but i am going to be SOL going forward as i can't afford another laptop for a very very long time and don't want to be chucking money on this that and the other to try and solve the issue that might not solve said issue.

Update 4:

HW Info is reading



Like WTF.

Also battery history from Windows is attached.





Thanks for any or all replies in advance.

[SOLVED]: Solution

Sounds like a faulty mainboard to me. Nevertheless, I would go with resetting everything to default, including BIOS (full reflash to stock) as well as EC firmware.

 

EC firmware has been done. BIOS has been reset too, but will try flashing the bios next.

If it's a faulty mainboard I am defo screwed, I take it your thinking the Power circuit has started to fail?.

Thanks for your reply.

Edit: just reflashed the bios, although I very much doubt it will solve the issue.

Yup, there are components that are prone to failures when used intensively above its designed specification, and when your system acted strangely like that it could have been those, and we can't see this with our bare eyes.

 

Well it didn't fix it. Which is a shame.

I bet is something that can't be fixed via board repair either.

Update: Right so I have gone and switched to IGP and I am running right now valley like I did with the dgpu, it's still doing the -700+ crap on HWInfo battery readout.

Managed to find someone i know whom has the GT72-6QE so will be able to test the PSU on that.

I can't complain laptop has been on for over 3.5 years of its life 24/7.

Do you still want to fix it? Ask MSI to find out how much it would cost to see if it's worthy to do it or not.

 

I am way out of warranty, so that leaves my options wide open. If I can get it fixed then yes. However the last time I contacted MSI for a part it was well expensive I mean like £100+ for a battery quote plus having shipping on top. Not only that I would need to send it outside the UK, not only that the chances of the stock being there for board replacement is be very slim and I have heard horror stories of laptop repairs via RMA.

My head is just all over the place as I don't socialise IRL most of my socialising is online with people that I talk to in communities such as NBR.

Ok, after hours and hours and calming myself down (Yes i was in a major panic), as well as inviting my brother in-law over with his laptop which cost me a sunday lunch I found the issue not to be a Power IC, PSU issue but it was down to the Intel ME Firmware Update.

So anyone with a GT72 do not flash Intel® Management Engine Critical Firmware Update for Security Vulnerabilities (Intel-SA-00213). It will mess your system up big time.

@Kevin@GenTechPC Thanks for your help.

 

So, are you able to fix it or is it permaborked ?

 

Well currently running Destiny 2 right now and it seems to be behaving, however going to replace the GPU fan and battery the latter being needed big time and then when replacing battery will flash the SPI Bios dump I have back to the chip which should then get Intel ME working again fully without the issue.

Better to try and use clean_me, than to re-flash a previous ME versions, or at least, use ftpw instead to mess with intel ME, so at lest your system is running and you can test the ME(with ME Manuf) before rebooting and finding that you have another borked ME firmware.

I always update my ME with fptw and firmware binaries from win-raid forums, never had a problem, just read the posts about updating it very thoroughly and it will be fine, make sure all versions are correct so you dont cross flash something incorrectly.

Regarding the battery, you wont find a battery below 80€ on ebay/aliexpress, 100£ for a known original directly from MSI is not that expensive.

 

@senso thanks for your reply clean_me ? i Disabled it via the UEFI Bios (Please don't do this unless you have SPI Dumps of the bios) so its in temporary disabled mode.

I have SPI Dumps so can reflash the Bios chip to get me back and run then fpt -greset after should see it working again.

As it sits now Intel ME can't be flashed via fpt via Windows or EFI Shell as well same goes for MEinfo or MEManuf

Code:

Error 86: Communication error between application and Intel(R) ME module (FWU client)
Error 81: Internal error (Could not determine FW features information)

As for battery calling MSI today about battery.

 

MSI gave me a £150 estimate however i have to wait till Feb 8th before anything can be done, not sure what the warranty on the battery will be however i am hoping that getting it from MSI would make it easier. Its either that or taking the Dangerous router of replacing the cells after all they are SANYO 2500mah 18650 battery cells, which means its a 3 Series 3 Parallel config and more then likely the protective versions too i.e low amperage ones aka 10amp CDR's.

 

Ok just an update I decided to run battery calibration again it kept itself at 11.085v before reconnecting AC power.

It did -727.4w for a split second before staying at 27w drain.

It's currently recharging as we speak and the time to charge started at 2 minutes and is slow showing longer times.

Now before hand it was going down to 10v range and shutting off.

Very strange. Any battery experts around?

New battery arrived today. Was a PITA to get the old one out but I am now doing the cycle run on the battery to see if it's a decent or dud.

Not sure if I can place where I got it from if it turns out to be a good battery so others in UK know where to get them from.

Even the fan turned up today. Timing couldn't be any better.

Update: Right so here it goes.

The battery i purchase first, although worked in terms of it charged to 100% and discharged (took way too long) was sent back due to it not working with the EC. Unlike the stock battery when the EC reset was performed the system still booted off battery with the AC Power Supply disconnected which was a big big no no.

The other issue with that battery was even with Windows saying 100% charged it was still drawing 30+ watts from the PSU also big no no, so i sent the battery back under RMA and got refunded without issues. I then purchased an Original MSI battery BTY-L77 from MSI which is working great like it should.

So moral of the story is if you can purchase the battery from the OEM please do so might save you the headache of having to strip your laptop more times then is really required.

The system is now working great everything is back to as it was when i first bought the laptop. The bonus is after doing what i did to the Intel ME (disabled it, however i suggest you don't do this), i am now happy as larry.

So if the mods could be so kind and tag this as solved as i can not edit the title thanks in advance!.

 

Hi,
where did you get that crappy battery? Ebay?

 

Surprisingly not from eBay. Got it from batterydept however they was quick to accept the RMA without fuss and refunded both the cost of the battery and return shipping.
