need help for upgrade and restore my gt70 2OD

[Johnt31]

Hello everyone,

I need help with my MSI GT70 2OD 075FR

I have my motherboard and gpu who are HS.

I found on alixpresse a motherboard and a gpu but this one is not a 780m I replace it with a 970m

my questions are simple :

1) do you think it's a good thing to replace everything ( motherboard 162 euros + GPU 177 euros )?

gpu 970m 1: https://fr.aliexpress.com/item/32958128785.html
gpu 970m 2: https://fr.aliexpress.com/item/4000021397378.html
gpu 970m 3: https://fr.aliexpress.com/item/33057743915.html

motherboard: https://fr.aliexpress.com/item/33035028140.html


2) am I obliged to modify the heatsink with this card?


3) do you know the size of the thermal pads for the cpu and the gpu?

thank you for your answers

best regards John

HS?

"Upgrade" and "restore" are two very different things. Does the notebook work now? Why does it need to be restored?

It sounds to me it is just time to shop for a new notebook.

Hello,
not a bad flash bios
my pc is stopped at once and can not be turned on again.
I have the pc tested at a specialist, he told me that the motherboard the pch is dead and gpu same thing

do you think it's a good idea to change motherboard and gpu for 345 euros i've got 4700mQ and 32 Go RAm and 2*256Go SSD MSata.

Replacing MXM GPUs is always very risky - you could run into BIOS whitelists, cooler incompatibility, power delivery issues, or a host of other niggles. Or it could work perfectly, of course, but there is definitely some risk to such an endeavor. Replacing the motherboard should be okay as long as the replacement actually works - in my experience, servicing laptops is a lot less scary than a lot of people think. And of course you're lucky enough that your CPU is socketed, making this a lot cheaper than with more modern systems.


My advice: if you can afford to lose the money, try it. If not, don't, and save up for a more modern system. You should be able to find a lot better performance in a slimmer form factor or with better cooling these days.

Both dead at the same time? Unless it's some crazy excessive liquid damage, I don't believe that's the case. Before you spend your cash on replacement parts, you should take it to your local electronics repair workshop and see what they have to say about it. It could be as simple as corrupted BIOS or failed stage on VRM, both of which cost less to repair than replace the whole board.

Also, motherboards off Aliexpress are always 50/50. I used to buy boards from the same vendor for 3 or so years, and recently had to stop. After my last order the entire batch of Probook640 and some Lenovo boards died within 2-3 months after installation (all 8 out of 8 boards). Just enough to get past the return/refund deadline. So, from now on I'd rather get a refurbished board locally at inflated prices (but w/ 6mo real warrnty), than wait 2 months for a board that'll work a couple of months before PCH fails or something drastic happens to VRM or standby rails.

Hello Silentbogo,

In fact my laptop stopped when I used it, no liquid damage.
I made a clear cmos and do a lot of manipulation a contact at msi d'as said to do but nothing the pc does not light anymore
no LED charging pc / sector either.

I sent him to my local electronics reapair he tell me pch on motherboard is dead and my gpu .

On Haswell and few generations after, if there is no reaction to charger, then it's most likely one of these:
1) bad DC jack combined w/ discharged battery, or dead charger
2) DC input mosfets are dead
3) Short on +5VSB or +3VSB (even if PCH is dead and shorts 1.05V to ground, it should still ligh up on charge)
4) CPU VRM is shorting it to ground (sometimes as a consequence of a dead CPU, but very-very rarely and almost never on socketed 4th gen). I've seen it only once on a newer Dell Inspiron 15 with very weird CPU power circuitry. Managed to fix it, but the CPU was still glitching out due to the fact that 19V went through SoC briefly when this failure happened.

Either that repair shop scammed you out of a perfectly working GPU, or they don't know whattahell they are doing and misdiagnosed your lappy by a price factor of x2.

he tell me cpu is ok "4700mQ"
I tested the charger 230v to 19v dc ok
I looked at the motherboard no trace of liquid or burn

just on thermal pad in the 780m have two traces of maroons

ok sorry for my bad translation edited
