[HARDWARE MOD] Clevo AC Adapter Mods

Recommended Posts

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.

      This modification involves going a step further than a straight ID chip swap between the 240W and the 330W. The reason I chose this method was, I did not want to perform the mod again in the rare case that the 330W died and I had to get a new one.
      In order to complete this mod, you will require the following items.
      1. Dell 330W PSU (This PSU was built for the M18X and X51 product lines). Part Numbers: Y90RR / 5X3NX / F0K0N / XM3C3 / 331-2429
      2. Dell 240W PSU (Either a Flextronix or Delta). Part numbers: PA-9E / J938H / Y044M / U896K / J211H / Y044M
      3. Dell or HP standalone PSU cable/Connector. I used a right angle connector but any Dell/HP 7.4 x 5.0mm barrel connector will work.
      4. M17x/M18X Power Jack. The part number for this power jack seems to be P01E. Look for the one that resembles the one used here.
      5. Small PCB designed for a SOT-23 packaged chip. (If using the Flextronics 240W PSU).
      6. Small housing (Optional depending on whether you would like to mod the ferrite choke housing)
       
      PSU DISASSEMBLY
       
      First we begin with the disassembly of the 240W PSU to retrieve the ID chip for our adapter. Since I had the Flextronics version some of these steps might not be the same for the Delta PSU. We start by lifting up the rubber feet on the bottom of the 240W using your nail or a flat tool. Underneath each rubber foot you will find a screw which you can go ahead and unscrew.
       
       
      One of the screws will be a tamper-resistant Torx T10 type, the difference to a normal Torx T10 being a small pin the centre so you would have to use a Torx screwdriver with a hole in the center.
       
       
      TIP: If you do not have this tamper-resistant screwdriver you can use a normal Torx T10 screwdriver but you will have to hammer down the pin at the centre of the screw slightly in order to get the normal T10 screwdriver to grip.
       
      Once you have removed all screws you will have to pry open the casing. I stuck a thin knife between the power plug and the casing to gently pry it open.
       
       
      The top half and bottom half of the casing are held together by interlocking clips. Twist the case a bit to get them to unclip. Then remove the PSU from the case. You will then be presented with the first metal layer which is held on by tape. Cut the tape and slide out the first metal layer.
       
       
      You will then see the second metal layer which is held in place by 3 points soldered onto the PSU PCB. It is indicated in the picture below. Desolder all 3 points and remove the second metal layer.
       
       
      The last layer is black and seems to be a type of flexible hard plastic. It will be stuck in place by white thermal stuff on the PCB, simply lift it and peel it away.
       
       
      Depending on whether you have a Flextronics or Delta PSU your ID chip will look different.
       
       
      Desolder this chip and keep it in a safe place (If you lose it, you have to buy a new 240W PSU). On the Flextronix PSU the chip is also stuck in place apart from being soldered on, so you have to work quickly heating the solder and pushing the chip away with a bit of force.
      To reassemble the PSU reverse the above steps. You can still use this PSU connected to the adapter with your M17X so it won't be collecting dust.
       
      THE ADAPTER MOD
       
      You will have to decide on whether you want to mod the ferrite choke housing into your enclosure or use a dedicated enclosure (small as possible as this circuit is tiny). If you are using a dedicated enclosure jump straight to the labelled wire photo to continue. If you would like to mod the ferrite choke housing continue reading.
      I did not take sufficient pictures during this portion as I was unsure if the ferrite choke housing would work. The rubber around the ferrite choke and the connector that I purchased was soft and very flexible which made it easy to work with. I used a knife and pressed against the rubber of the ferrite choke housing for a clean cut so that I could glue it back together. I cut off one end and then length ways along either seam of the housing making sure to leave a bit of extra cable.
       
       
      Here is a picture of what we’re trying to achieve with the cutting.
       
       
      You will then see the ferrite choke which you can crack with a hammer. Remove the pieces (be careful as they will be very sharp).
       
       
      Then the cut off the cable strain relief that's covering the cable with small wire snips.
       
       
      You will then see the cable which you can strip to positive, negative and the ID line.
       
       
      You will then need to connect those wires to the power jack. The two pins at the top are negative. The two pins at the back forming the shape of a U are positive and the pin at the back in the centre is the ID line.
       
       
      Solder the positive wire to positive pin and negative wire to negative pins as shown in the image below. The negative wire can be soldered to the negative pins and simultaneously joining the ID pin on the jack.
       
      The reason behind joining the ID pin to the negative pins on the jack is because we need to ground the ID line coming from the 330W in order for it to operate beyond its artificial 240W limit.
       
       
      Now all that’s left to do is connect the ID chip. If you have the Flextronics PSU the ID chip will be in a SOT-23 package and the Delta ID chip will be in a TO-92 package. The Flextronics SOT-23 package is difficult to work with and should be first soldered to a bit of PCB that had a SOT-23 package so that you do not break the legs off.
      I initially soldered the wires directly to the legs and moving it about in my "enclosure" to find the best spot to place it was too much stress on the chips tiny legs and they broke off... yes, all of them. Luckily I could still see a tiny bit of metal from each of the legs. I managed to salvage it by soldering it to a piece of PCB that I jacked from a broken mouse which had SOT-23 connections.
      The blue ID wire coming from the cable needs to be soldered to the data leg of the ID chip. Connect the remaining two pins from the ID Chip together and then to the negative connection on the PSU jack.
       
      Dont judge my pathetic soldering skills!
       
      Place your ID chip into the enclosure and test the adapter to make sure all your connections have proper contact. If it’s working properly you can close it up.
       

       

       
      I considered flooding the enclosure with silicone to secure the ID chip and its connections but I did not, as I thought it would be more work if one of the connections broke and I had to open it up again. You can do it if you like.
       
      I used a drill to make the hole at the centre of the disc large enough for the 330W connector tip fit through. I then stuck the enclosure back together using superglue along the sides and then attaching the disc. Add a bit of glue to the disc/jack so that the disc and jack are stuck together as well. This is so that the jack does not move when plugging the PSU connector tip in.
       
      THE COMPLETED MOD
       

       
      Pros/Cons over the ID Chip swap Mod
      Pros
      - Allows you to use any PSU irrespective of wattage as long as the connector tip is compatible with the power jack.
      - If the 330W PSU dies all you have to do is plug a new one in. No need to perform the mod on a new 330W.
      - No need to open up the 330W at all.
      - Your ID chip donor 240W PSU can still be used with your M17X by attaching this adapter.
      Cons
      - Allows you to use any PSU irrespective of wattage as long as the connector tip is compatible with the power jack (Could be dangerous with low wattage PSU's).
      - A lot more work compared to swapping the chips.
       
      Notes: I also had to trim a bit of rubber at the right angle connector for the cable I used as it’s a bit of a tight fit if you don't. The rubber around the connector did get a warm at the right angle after testing but it's being blasted by the heat of the CPU fan continuously so I don't think it’s the connector itself that's causing it. These cables are very short and should be able to handle the power easily.
      Since there are two positive terminals you will have to either split the positive wire coming from the PSU connector to each pin or join both pins (bend one pin over to the other and solder them together making sure to place an insulator to cover the ID pin) and solder the positive wire to a single point.
      Also worth noting is that this adapter mimics the original 240W adapter perfectly. So if you experienced the "plugged in, not charging" issue when connected this adapter will not resolve it (I still have to pop the battery and clip it back in to resolve).

      Hello Everyone,

      I am trying my Sager NP 9377 to get to work but to no avail. NO POST, NO DISPLAY.
      in short>> powering on laptop causes fans to run at full speed after 10(cpu only) + 10 (now both cpu+gpu) with Caps Lock + Num Lock + Scroll Lock LEDs blinking, continuous 1 second beep, repeats for one minute with 1 second in between, then laptop shuts down.

      IN DETAIL
      System Specs are i7 4810mq 8gb gtx 880m SLI variant (though my laptop has other GPU Slot empty so only singular 880m running) 120 Hz display.

      The Problem
      > if i take out the battery and plug in AC only, the power light comes on ORANGE
      if both battery is connected, then i have both power and battery light ORANGE
      and if only battery is connected then of course laptop is waiting for me to press the power button
      but in all 3 cases the following happens
      > Pressing the power button brings laptop to some signs of life, power LED turns green, both the CPU and GPU fans have a very quick jerk but does not spin., keyboard lights up with Blue Backlight (dont know if this is relevant or not), HDD activity light starts to blink showing HDD access maybe (even when hdd is removed)
      > Display remains blank (i dont even sense the display backlight being on)
      > HDD activity light sometimes goes off after only 1-2 seconds, sometimes shows rapid blinking/activity for 4-5 seconds
      > both fans remain off (i removed back cover to check this)
      > after about 10 seconds or so, the CPU fan spins up (speed is normal, just like when using the laptop in IDLE)
      > after 10 more seconds have passed, the CPU fan seems to be turning off for a split second then both the CPU and GPU fan turn on full speed with a lot of noise.
      > Caps Lock, Num Lock and Scroll Lock LEDs all blink together with single beep for about 1 second, repeats beep with 1 second in between.
      > goes on for about 1 minute then laptop shuts down.
      > forcing the fans to spin down using FN+1 key makes them spin back up to full speed after a split second (dont even know why i tried this one -_-)

      What I Have Tried So Far
      > EC and Bios Reset (take out battery, disconnect AC Adapter, disconnect CMOS Battery, Press Power Button for upto 30 seconds)
      > Change Ram and check all available slots
      change/remove HDD
      > Repaste CPU/GPU and clean out fans
      > Checked GPU...... Flashed the 880m in this Sager with MSI vBios and tested it in a MSI Gt70 2PC i have, gpu ran fine, tested with FurMark, AC Odessey, Ghost Recon Wildlands for over an hour (unfortunately the cooling in my MSI is not good enough it already runs hot, and this 880m causes thermal throttling as well as power limit throttling sometimes). Reflash 880m with original Clevo vBios and put back into the Sager, still no boot, same results as before.
      > Checked the CPU..........checked the 4810mq in the MSI GT 70 which worked fine, as well as tried the 4810mq from the MSI in the Sager, still no boot.
      > Suspected bad GPU fan connection......therefore forced both fans to full speed as soon as i press power button (using FN+1 Keys) and both fans turn on full speed, same results.
      > tried charging the battery to the max before turning on on battery only, same results.

      >>------- The laptop has had some random shutdowns in the past too during gaming but would turn back on fine after waiting for 10 mins or so, then i sold it to some guy who brought it back to me the next day saying that it just turned off during gaming and wont turn back on, i returned his money, did all the troubleshooting above to no avail. then i finally put it aside to wait until i get some other system in which i can test the CPU and GPU.
      Then one day i turned it on (after leaving it untouched for a couple months), same results as above, i decided to try once without battery and it Freakin Turned ON!!!, used it for a couple days without battery, played a few games (thermal throttling was observed here and there), but then this happened again and this time it seems permanent . And now i have not only repeated all the steps above but this time also checked the CPU and GPU in the MSI GT70 too. ------------<<


      Some Observations
      > touching the CPU heat pipes feels warm, but the GPU heat pipes are colder (GPU never even booted?). dont know if this is normal or not.
      > i replaced one of the capacitors near the CPU once, but i did use the laptop for quite a while after that without any issues.
      > my Idle temps were always below 40c for both CPU and GPU, so an overheat warning as soon as laptop is powered on seems unlikely (false overheat warning?, but GPU does not even seem to be detected/ booted as heat pipes remain cold to touch), also i repasted the CPU and GPU multiple times.
      > The guy who sold me the laptop told me that the power adapter was originally a Dell, and it was modified to use with this Sager by replacing the cable with a 4-Pin one from a Toshiba (same pinout as the Sager), but then again i have used this laptop for quite a while on the same adapter.
      > From day 1 of having this laptop, some keys on the keyboard (w, s, t, c and numpad 4) did not work 99% of the time. pressing really hard on any one of them sometimes made ALL of them work for a while. any thoughts on this issue?? (even if its unrelated).

      So what seems to be the issue here?
      GPU not detected ?, False temperature alert?, Bad fan?.
      Any help towards resolving this will be greatly appreciated.
      Thanks in advance .

      I recently purchased a replacement 980M (Clevo model) for my P770DM-G after the original died, however, after installing the card the laptop doesn't boot. I only get a black screen, and after a couple minutes the fans spin to max before shutting down, which is the same thing that happens when I try to boot it without any gpu at all. I've tried the reset procedure, unplugging, removing battery, and removing CMOS, to no avail. It does beep before shutting down (I counted 22 times exactly). Anyone have any insight as to what the problem is?
