[HARDWARE MOD] Clevo AC Adapter Mods

Recommended Posts

Guest

Hey guys, thought I would share a couple of very simple mods I did that others may benefit from. 

 

My P750ZM came with a wimpy little 240W AC adapter, that's really not adequate for a heavily overclocked 4790K and GTX 980M. I had a spare AC-100 (dual adapter) converter box and a spare Alienware 330W AC adapter.

 

I purchased one of these dongles to convert the Dell 7.5mm connector to a different size AC plug. It does not matter what connector is on the male end, all we need is the Dell 7.5mm female connection, so any similar dongle will work. The wire gauge is smaller than I would like it to be, but the cable is short. So far I have noticed no power handling restrictions. The cable and end plugs on the dongle do not get hot, so it seems good in spite of the small wire gauge. If you can find a dongle made with larger gauge wire that would be a better option than the one I linked, but it does seem to work fine. So, what I did from here is I sacrificed the crappy little 240W adapter and stole the cable off of it. I used the original cable and strain relief boot from the 240W adapter to replace the silly short pigtail on the AC-100. I soldered it in place of the short pigtail and it looks factory.

 

When soldering together the custom dongle, be sure to wire it correctly. Solder white to white. The ID signal wire and ground wire should be soldered together and that will tell your Alienware AC adapter to output the full 330W capacity. 

 

I used the short pigtail from the AC-100 converter and spliced it with the Dell adapter dongle, so now I can plug the 330W Alienware AC adapter into that dongle and connect it to a 4-prong Clevo laptop AC jack... easy-peasy. I can put my spare 330W Alienware adapter to good use on my Clevo laptops and now I have a nice long cord on my AC-100 converter box.

Hi, I tried to solder the original plug-in jack of my 180w PSU to a DELL (  Flextronics) 240w PSU. I connected the ID wire to the ground and white to white as you instructred, but the Adapter shuts down 1-2 min after GPU is under full load. I have a Clevo P157SM and upgraded 2 summers ago to a GTX 980M which needed more power. It is only doing this while using prema's vbios. I didn't change any settings. My laptop was working well with the 180w as well, but many users reported that it needs more power. Need a bit of help. Thanks!

What are you doing that shuts it down? If you're cranking up the GPU voltage you can still shut down a 240W with a single 980m.

Really?? So I need a 330w PSU? It only turns off if I use Premamod vbios, without tweaking the voltage.

Without overvolting it should not turn off. Where did you connect the ID line to GND? The PSU needs to see the grounded ID line, not the laptop.

You can see in the picture. I was having this issue with my old unmodded 180w PSU as well.

      Hi All
       
      I've been searching all over the internet and these forums in particular and I just can't seem to get any answers regarding GPU upgrades for the Clevo P150HM. Neither can I get any real info on the difference between the HM and the EM model - the EM seems to be the much more talked about model.
       
      Anyway, my current GTX 580M is causing a black screen very occasionally and I decided to purchase a used GTX 980M (N16E-GX-A1) from aliexpress as a replacement.
      The seller isn't giving me much information and I am unsure if they've flashed the vbios on this card themselves, regardless of that I cannot seem to find a custom BIOS for this laptop either, the closest I found is P150EM_17_11_PM_v2 which is obviously for a EM not a HM model, again I don't know much about these two models and if attempting a flash with that BIOS will brick my laptop.
       
      The 980M is the correct form factor, it fits in perfectly and even warms up when I turn the laptop on, I can see the POST screen display but then it simply maxes the fans and beeps out until it shuts down. It would seem to be a pretty clear indication of incompatibility.
       
      Model: Clevo P150HM
      MB Series: P150HMx
      BIOS Revision: 1.01.14
      KBC/EC Firmware Revision: 1.00.12
      Another version number listed (not sure for what): 2.10.1208
       
      I understand this is both an old subject and an even older laptop, but I would be extremely thankful for any help available and I am willing to drill down to create my own custom BIOS if necessary but I just need a point in the right direction.
       
      Failing all that, its not the end of the world as they've already agreed to a return and refund if I can't figure this out.
       
      Thank you.

      Hello, I have bought an empty case and assembled parts of Clevo P775DM1. Basically the laptop had no display or MXM Gpu or CPU. For test case I had a CPU lying around G3900 and put it in. I also have mxm gtx 965m Clevo card. I also have installed screen from alienware laptop 2k resolution 120hz. Now the problems.
      1) The laptop boots without a hastle. But as the nvidia drivers load the screen goes black and stays like that. At first I thought the GPU was dead but the external screen worked. Then I though maybe there is a problem with GPU not being recognized or something. Downloaded GPU-Z and every sensor is working fine. I tried saving vbios file and suddenly screen turned on. It probably disconnected the GPU and reconnected it again and as long as the laptop is on, GPU works without a problem. But if I restart it, the laptop screen turns black after boot and external works fine. That's the first problem.
      2) The second one is with Ram and I don't exactly understand the problem. I have 2x8GB rams 2133. single channel works without a problem, but when I try to use both of them the laptop does not boot at all. Won't start fans just blue led keyboard lights up. in single channel both rams work with no problem. And I've tried both slots, since the laptop has 4 slots. Still not working. If you can help with any of the problems, it will be much appreciated.
       
      p.s. I have recently bought the laptop and haven't really figured out anything around it. if you have any extra pointers/bios mods I'd really appreciate it as well.

      I've been scouring the internet in search of anything regarding an updated bios for my Clevo P170SM. I have found many mentions of Prema Bios mods on various websites, but good luck trying to find actual download links. They all seem to vanish or have dead links. Wayback Machine doesn't help either and I was only able to find stock Clevo bios as early as 2015 via the WayBack Machine. If anybody has an updates Prema Bios or some other unlocked bios file for the P170SM, that would be fantastic! Otherwise, I might have to consider paying over $100 to Eurocom for their unlocked bios.
