Possible GPU upgrade for Precision M4600

Well I removed two sodimm slots and now the laptop won't boot due to it thinking there is no dimms present.

I guess if it cant read a lack of signal it can't move on to the dimms that are present, thus preventing it from booting.

Unless anyone has any ideas, this project is dead RIP m4600 lol

Ill probably not replace it, I think I may get the m6700 if I do get another precision. Then I could at least have the 980m for upgrade path.

 

I wonder if the top slots and bottom slots are connected in some way that is not apparent... Removing the top slots may have broken a connection to the bottom ones.

 

It could be, but I also removed the pins connected to the board so it can't detect anything since there isn't conduit to carry a signal anymore.

If another brave soul tries it I would cut the dimm slots but leave the pins and you might have better luck.

I wanted to make it a clean look. Well there is likely still some pins left in the board so maybe I might try to pull everything. Physically you can make the card fit with some modifications to the cup heatsink and removing the rfid socket.

 

"Removed two dimm slots"? How exactly? :O

 

It's exactly as you quoted, physically remove two slots to make clearance for the gpu.

I may try again in the future the motherboard only cost about 30 usd

 

I was wondering more about the method - a pair of pliers, hammer & chisel? Or some sort of (really) wide-tipped soldering iron, or hot-air station?

If you did it purely mechanically, i would've expected "a few" ripped-up traces, if not even shorting the RAM power rail to ground or something.

 

I used a cutting disc to cut it down, then one by one pull the pins with pliers, most of the traces are still in the board.

If I do it again I'll just leave the pins but still cut it down, that's a requirement for getting the board to fit

 

Yeah, that'll be your problem right there...

As labor-intensive as it is, i would've gone with slicing through the plastic with a box-cutter or xacto knife or something (the plastic "between" the two layers of contacts), and then remove the pins with a soldering iron. But that's just me...

Pulling the pins with pliers was the... sub-optimal way to go :/ Even if "most of the traces are still in the board", my guess is some power and/or address or data pins (or traces) are touching together or something (the top two slots are in parallel with the bottom two slots, so if one on top's messed up, it'll screw up the signaling for the bottom one).

 

Using a knife would not be a route to go at all. I've never used a xacto knife capable of that, and this was not a requirement, not slicing myself up for a gpu upgrade. Especially when a cutting disc will do the job without removing any traces at all.

I pulled the pins because I didn't want to run the risk of the gpu making contact and short circuiting.

I never used the thing anymore, but I may still give it another go, I can probably fix it and my old y510p.

 

Hi dears.
I finally upgrade my gpu to m5100 on m4600 and it work very good.
but i have question :
1.which is best driver for install?
2.And i can't adjust brightness in windows 10. how can i fix it? (for intel hd 2000 there is a registery edit to fix and i always did it, but i try all registery edit in google searchs for m5100 and no success)
