looking to just upgrade my M15x much as possible as a project ( cuz i like learning :3 n tinkering ) will list what it has and what i done so far with questions. the point of this post is see every possible upgrade i could do then do it. i dont however wana do big moding jobs on it, but i am ok with small ones. i have taken apart the computer 3 times to clean,upgrade and just paint the outside.

BUILD

started with > done > Next upgrade?

• also ok upgrading upgrades i already done, like my CPU *

OS: Windows 7 >Windows 7( fresh install) and Ubuntu 16.04 LTS

CPU: i7-720QM 1.6 GHz L3 6MB > i7-920XM 2GHz L3 8MB > Next upgrade?

GPU: GeForce GT 240M ( this need a huge upgrade )

RAM:2x 1gbs > 2x 4GB 1.33v > next upgrade? ( read below )

MOTHER: intel PM55 Express chipset CPU socket : BGA1288 /socket G1

STORAGE: HD 250Gb > SSD 500Gb

ETC: missing charger and battery > got both from online

Commets/Questions

OS: would puting windows 8.1 be a good idea? ( i hate win10 soooo much)

CPU: what is better GHz or the cacha? like 2GHZ L3 8mb VS 2.8GHz L3 4mb, the 2.8GHZ also runs at a lower watts ( 55 >35) but also has a GPU on it may need a heat sink mod so both tops get love. also not fully get what makes a cpu work or not work with a motherboard then the chipset? googled n got chipset for some site to see what CPUs it can use cuz it only asked for whats the chipset.

GPU: easy this is the most behinde part of the labtop and what is the best upgrade can i do with this? seems ubuntu likes nvidia more then ATI but if ATI has a much better card then i am willing to suck up with lil bad drivers still ubtuntu gets a good ones for ATI

RAM: got two 4Gbs on it, people say they are doing 16gbs with two 8gbs. some say its pure luck if it works or not..... this cant be true that its lucky. has to be a way to know what will work. the motherboard has the volt options for ram 1.5V 1.6V 1.7V

its also DDR3 and memory frequency is 1333 MHZ

MOTHER: petty sure i cant upgrade this lol. i did however upgrade the BIOs A02 to A09. got ton better at cooling. this labtop was my friends that gave me it, had huge heating issues. not agisnt modded BIOs too but what i found seem to not be much better then the A09 stock

STORAGE: hard drive to SSD. i know i will get a 1tb or more to give better room to both windows n ubtuntu. right now i got 2 500gbs, one windows 7 the other is ubuntu. what is the fastest storage and is it wroth it?

ETC: when i got this. didnt have a battery or a charger, got both on ebay. both was ever used and in great shap. labtop runs with 150v right now too. cooling wise. it ran SOOOOO HOT but the huge BIOs update fixed it. now its not even close to how hot it was. now sits at 60 to 70 on cpu. the gpu is runing at 50. both temp checks are aftering idling on tf2 for HOURS, like 4. i also added lil legs to the back of it n added a vent right over the top of CPU n GPU. cooling wise is great so if any upgrades make it got alot hotter, will be ok. i even got fully new heat sinks for both cpu n gpu ( and yes added new thermal paste, it was sooo dry n crusty)

The End

Thank you for reading and dealing with my poor grammar n spelling. i hope i learn alot from this post :3 thank you to everyone who posted n share their though n info

This laptop won't turn on after a power cut. When the charger is plugged in the power brick light goes out. I felt a mosfet get hot so I removed it and when the charger is plugged in the brick light stays on. I replaced the mosfet but goes back to the same issue

I'm sorry if my question was confusing but I was talking about a motherboard swap. Not just a gpu or CPU replacement specifically.

Initially it would go back to functional if I either (a)change to a external Bluetooth speaker or (b)just leave it there with audio going, both for about an hour.

Recently it has turn completely quiet, other than the ticking, and the two method above no longer works. I assume there's definitely something wrong with the speaker elements as both the 3.5mm jack and the Bluetooth function are perfectly fine.

I would like to know if any other owner of my model meets such problem, and what might be a fix for it? Thanks.

AC adapter light flashes once plugged in to laptop. It then has to be removed from power to reset it. Kinda like it senses a short when plugged in and goes into a safe mode.

I have replaced DC input assembly inside the laptop. Checked all connections to the best of my limited ability. Looking through forums , the next step seems to be replacing the mainboard. Just wondering if there is a test to determine if this is really required.

Thanks for any info

Cheers

Service Manual: https://www.dell.com/support/manuals/en-...

Issue: When I press the power button, it lights up in different colors and shuffling through them until I press and hold the power button again for about 8 seconds to turn it off. The fans do not turn on and the display doesn't show up. I also tried an external monitor, with same results. I've reseated the battery, SSD (x2) and same issue. I’ve tried this with the charger plugged in, with and without the battery installed, but same issue. Any advice would be much appreciated. Thanks!
