    Hey everyone!
    I just picked up a M15x and its super slow. The guy just restored it to factory via the dvd and it seemed ok before i purchased it but upon getting it home the menus are so slow. I updated the drivers even tried windows 10 but its a sloppy mess. I tried to install a basic game from Steam and it ran so slow and poorly. Now i have 15+ years troubleshooting computers but for the life of me, cant put my finger on what is causing this slow down. I know its a popular laptop and people claim to play some amazing games on it but I cant see this happening on this guy. I can see it running poorly in latest games but just windows and browsing is lacking performance.

    The SSD is old, 8+ years?
    Video is the 470m
    CPU is the 1.86Ghz version
    8GB DDR3

    Any help would be greatly appreciated

    If the battery is any good, unplug the power adapter and see if it runs better. When i got my M17X it was slow as hell because the power adapter wasn't giving it enough power.

    Mine came with a Dell 65watt adapter... which gave the laptop enough power to "run". The original adapter died some years ago. The 65watt didnt even have the power to charge the battery.

    lol 65w is nowhere near enough to run that system, CPU alone will eat 35W

    The battery being removed worked! Its a ton better then it was! I can even now put the battery back in, left it overnight plugged in and its working. I currently have what i think is a 150W adapter. Delta Electronics PA-5m10 family DA150PM100-00
    I just ordered the 240W adapter online just because i plan to upgrade a bit.

    Next i need to find a list of compatible video cards that will fit in this guy. See whats most cost effective and I dont have to do crazy support.

    GPU that are compatible? Try:

    AMD in order weakest/cheapest to strongest (top end cards for each generation listed only - lower end cards work too)

    5850/70 1GB GDDR5
    6970M
    6990M (avoid - hot card)
    M6000
    M6100 (great buy essentially better than M290X or 680M when heavily OCed)
    7970M
    8970M
    M290X
    M390X (not tested yet but is compatible - comparable to 970M but cheaper and hotter)

    Nvidia

    260M
    280M
    460M
    470M
    480M
    485M
    675M
    770M
    680M
    870M
    780M
    880M (avoid - hot card)
    970M
    M4000M (rare and usually expensive)
    980M (avoid - hot card for most part)

    Also get yourself a 920XM or 940XM whichever is cheaper, install throttlestop, overclock all cores to 3ghz+ under decent thermal paste and thank me later. If you intend to upgrade GPU to top half of either list above getting am XM cpu is a must if you don't want to severely bottleneck your gpu.

    This is such a valuable post! Thank you for posting it! Unfortunately I have already purchased a few items so i didn't give it the best search as i could have apparently.

    I just finished installed a 920XM with an HD 8950. I paid about $100 for both!
    Also a 240W PSU with the 90 deg adapter but dont understand the "pin" mod i keep reading about.

    You mention overclocking and throttle stop.
    I dont see anything in the bios to overclock 008 bios.
    I also ran throttle stop and dont see any changes.
    Please advise

    Throttlestop will take a little learning - but there is lots of info on the Throttlestop board, and lots of people who will help you. Throttlestop is particularly useful for enabling this machine to do all it can. Have fun! Joe
