CPU voltage changing and dark screen problem.

Recommended Posts

Please help ! I Have 150SM-A laptop with PREMAMOD bios. Everything was ok but I hanged CPU and RING voltage to add 100mV and ovveride to 50mV. Now laptop does not boot up only blank screen is present. I tried to reset bios by removing battery from laptop and from motherboard for few minutes. Unfortunatelly after this nothing changed. Laptop switchen on for few seconds then turns of and turns on again in loop. The screen is dark.What can I do ?

Settings like these are stored in the NVRAM, which is a section of the bios. Changing hardware triggers resets in the NVRAM for the hardware that was changed.

 

I find it very odd that raising voltages triggered a brick. I personally have bricked my p150em due to quirks in changing memory speeds. You should first pull a memory stick and boot. If that does not fix it, pull the cpu and try booting. Obviously it won't work without a cpu, but when you put the cpu back in the motherboard will read it as a hardware change and reset cpu settings.

      Which one of the above is the official website dedicated to Prema BIOS mod and why they all seem dead? Including the last one - according to TechInferno, Prema's last visit here was on Dec 2, 2016. Is Prema long done with creating custom firmware?

      When my first CPU fan on Y500 is broke i replaced it on something compatible (non-original) and planned to replace it later on original. Since that time happened a lot things, but i still using that non-original fan. But i did some research and here is what i founded:
       
      I. ORIGINALS
       
      1. Forcecon (marked as FCN on fan)
      DFS5413005MH0T-FC1C (5V - 0.5A)
      Spotted in: Y400, Y500.

       
      2. Asia Vital Components (marked as AVC on fan)
      BNTA0612R5H-P007 (5V - 0.5A)
      Spotted in: Y410p, Y500, Y510p.

       
      3. Sunon (marked as SUNON MagLev on fan)
      MG60120V1-C230-S99 (5V - 2.25W (0.45A))
      Spotted in: Y410p, Y500.

      So, which to choose? Any recomendation? Maybe there also unexpected way (completely diffirent fan from another company for another laptop)?

      Hi everyone, I have an unusual request. I have an i7-3940xm in my M17xr4 and it's difficult to keep cool. I have already done the m14x fan mod and I'm using Thermal Grizzly Kryonaut thermal compound... it's just not enough. The CPU is constantly being throttled (my bios settings in a11 unlocked are set to throttle it 85 C) when under load, and it will sometimes see temperatures in the mid to high 90s. The maximum operating temperature is rated at 105C, and I have a thermal shutdown set in bios for 100C, which it hasn't yet reached (but it gets scary close).  Even when throttled, it's still an upgrade and runs better then the stock 3630qm, but I don't wan't it to throttle all of the time. I know I could underclock it, but what's the point of having an upgraded CPU if you're just going to downclock it to similar specs as the original (baring cache, of course). At idle, by the way, it jumps around mid 50s to high 60s.
       
      Anyway, to keep it cool, I want to try using a peltier cooler. They're thermoelectric ceramic devices of which one side gets hot and the other gets cold when an electric current goes through them, for those who didn't already know. I figure I can sandwich it between my cpu and the heatsink and try to help keep the cpu's temps a little more reasonable. I have one of a workable size which can withstand temps of up to 135C, and I've done the math with it's specs so that it hopefully knocks 25ish degrees off while at full load and not overheat the peltier doing so. This leads me to my question/request; I need to know if anyone would know a place on the motherboard which supplies voltage when the laptop is running, but not when it's off, whether or not the charger/battery is connected? I have found a few good sources on the MB which can withstand the drain, but they're always hot, even when the laptop is off. I have a multimeter and have been probing, but I don't want to disassemble half the laptop and attempt running it in pieces to verify a good source. If no one knows off hand or has any idea, does anyone know of any schematics or files which exist which contain voltage information of various contacts on the m17x r4 motherboard?
       
      I know this is a strange request and most will not be able to assist, but before taking it all the way apart to probe around I thought I would at least ask. I'll make a write-up on how it's done and how well it works if it's successful, as well as a controller circuit if necessary using a teensy 2.0 or something.

      Hello All. I have a question:
       
      I need to repaste my laptop. To clean the old thermal paste, i went to the pharmacy and bought an acohol solution with 78% alcoohol (highest content they had).
       
      However, the same solution is also 2% salicilic acid. There are no other components in the solution (except 20% water). Can i usr it to clean the CPU anyway?
       
      Thanks!

      Have Clevo P170SM and working music and video production. Processor: Intel core i7 4800mq 2.7GHz with turbo boost up to 3.7GHz x8 (47W), Graphic: Radeon R9 M290X 256BIT 4GB DDR5 (100W) + Intel HD 4600, Memory : 24GB DDR3 1600MHz, SSD 3x Samsung Evo 1tb,  and interested for upgrades, so if somebody have experience with GPU NVidia GTX 1070M 8GB (150W): https://www.digitaltrends.com/computing/gtx-10-series-mobile-reveal/ and CPU AMD Ryzen 7 1700 (65W) : http://www.trustedreviews.com/amd-ryzen-7-1700-review. Of course I will have to change memory with DDR4-2400, but question is, will the 230 watt power adapter be enough and should I expect some more problems (except money) to do that. Thank's in advance.
