  1. Oof, Sorry for not seeing this earlier, I haven't checked Tech Inferno in a while. I'm glad you were able to get it going for a while there, but sad that it's back to somewhat broken. Remember, these laptops have 2 to 3 different chips that they update firmware on, not just the main BIOS chip. The main BIOS for the system configuration is on the labled chip, but I would suspicion that the EC Bios and the ME bios are on different ITE quad package chips. If those firmwares are not properly matched to the main BIOS, it can keep the system from posting. My guess is that you are successfully flashing the Main BIOS, but one of the other chips still has a mismatched version of that firmware, and they are conflicting now. This is just a hunch on my part though.I would guess you have put this on the back shelf by now and suffer from repeated nightmares of flashing endless BIOS's... I wouldn't blame you. That's never a fun part of trying to build systems for customers.
  2. If this started happening with normal use, then (barring a fan issue) the problem is most likely one of the chips failing in some way. I would have to go through the schematic, do signal tracing tests as well as general oscilliscope testing, to try to figure out what is dieing. When the road startes getting really rough, it might be heading to a dead end.. I never had to go that far, though. I am in the posituon, that if a board is failing at that level, I get to RMA it back to Sager for repair/replacement.
  3. There are service manuals that you can find which have the schematics, voltages, component values and power-up sequence in them. If you feel capable of doing so, you can troubleshoot the circuitry at a component level, but that is over most peoples ability. The schematics are always a fun read though. As far as sourcing parts.... I don't have any insight there to provide.. I was working with the supplier for repair and replacements when needed. There are several components on the board (inductors, resistors, mosfets) that can go bad and mess with the primary power and charging functions, and you can find them on the schematics easily, but the replacement is a bit more tricky in sourcing the right parts. And after sourcing them, comes the removal and replacement of surfacemount chips, which can be a trick as well.
  4. This sounds simmilar to something that i have seen on several laptops that we carried. Something in the way the cpu or gpu were reporting their temperatures to the EC BIOS wasn't working right, or the ec bios itself was crashing or not detecting a good signal from the monitored devices, and it was entering a panic state (turnign on all fans to attempt to keep cool, then shutting off after a 10 count to protect the system.) The keyboard issue, though, is likely a purely mechanical issue. Ihave had a couple new laptops where the keyboard frame wasn't stamped quite right, and all the keys had to be pressed really hard to make contact. If i smashed all the keys down really hard, it would slightly bend the tabs that each key mounted on, and made it a lot easier to get them to register. Not for sure, but that's what it sounds like to me.
  5. What you have happening is the EC BIOS shutting the system down to protect it from a failure at the "critical" level. That failure level can be triggered by various different problems. When you have a fan fail, the status lights on the side corresponding to the fans location will blink, along with the beep sounding, and then within a short time (I believe it is a 10 second count) The EC will cut the power to the system. But that is a fan failure, detected by the lack of a Tachometer signal. If the CPU or GPU are not reporting their own temperatures correctly, or at all, the EC will blink all three lights, and then shut down... the presence of beeping during this has been variable in my experience, sometimes beeping, sometimes no beeping. The main theme, though, is that the EC is in panic mode, and is protecting the computer the only way it know how to, and that's to shut down all power, and the EC only truly powers down when the battery and AC are both removed. The few routes of testing that are available, are trying a different CPU, trying a different GPU, Re-flashing the System BIOS the EC BIOS and the ME BIOS to the newest available, or having the Mobo replaced.. not fun.
  6. I have worked on a few of the the P370xx models, and they should be able to turn on and boot just fine without the batterypack in them. If the battery is out, and you plug it in, you should get a yellow light, indicating that there is power, that light should turn green when the system is powered on. If that light is not coming on, then you have an issue with the power getting into the laptop. I specify this, because it could be a problem with the power jack itself, inside the laptop, and this has been an issue with this line in the past. The connection inside the jack degrades and begins to generate heat, then melts the jack, fatigues the solder, and makes a bad connection. It is not a /hard/ thing to replace it /at my soldering skill level/, but most people are not able to do this. There is also a possibility that the power adapter itself is not working correctly, and the laptops power management circuit is designed to not accept dirty or bad power. You can try another power supply that outputs 19V, with the same type of connector, and see if that lights up the front LED, if it does, then the adapter is bad.
  7. If it's anything like the other Clevo laptops I've worked with, there are 3-5 chips that have 'bios' information on them. for a gamer laptop, there are two ITE subsystem chips (KB/EC), the main Bios chip, an ME chip.. Maybe a couple Video oriented chips to program as well. One thing you might look into, is the processor model that you have in there. Yes it is a good working chip, but some of the older bios's on the laptops won't post with a newer chip. You have to put in an older chip to get it to post, then flash bios's and then swap the CPU again. The same procedure would be done with the GPU if it isn't posting. It's easiest to find one that it will post with, flash bios's, then swap back to the better card. I'm sure it is possible to un-solder the chip and drop it into a programmer, but I haven't done the research to do that sort of operation on these laptops.

    Service Manual

    I am now looking for a Service Manual for the NP95xER, Sager NP895x. The Clevo Mirror site has not been updated with it yet. Brian
  9. Sorry, I think I might have misread yuour model number the first time. You can access/download the P650HS Service manual (with schematics) from https://www.manualslib.com/manual/1269646/Clevo-P650hs.html
  10. repasting it shouldn't be that hard. While you're at it, I always tweaked the springs up a bit so they applied more pressure, and that gained a few degrees in temps. Unfortunately, though, from the sounds of it, your GPU has fatigued and is putting off a lot more heat than it should for the work it's doing. I don't have the stats for the currents for that model, but I would not be surprised if it's drawing way too much current as well, either of which (temp or current) could be triggering the emergency shutdown. Which specific games and programs are shutting it down?
  11. I just found the Service manual for the P95xHR, I'm not certain how much different that is from the HS. Use with discretion. http://s472165864.onlinehome.fr/anyware/manuels/P95XHR.pdf
  12. It's really frustrating to me to have a new BIOS update, or a new model of laptop to flash, and for some reason or other, the flash goes badly and the system is bricked. The only recourse is to get it reprogrammed by sager, since it won't boot. I know there are chip programmers, but I know they have methods of flashing the BIOS, ME, and EC without removing the chips from the board. Are they using the Debug connector to do this? is it possible that I could get the specifications needed to recover the BIOS in the same way? What kind of Programmer interface would I need, and what would the pin-out be for the appropriate connector? Right now I am working with the P775TM1-G, P650HP6-G, p650HS-G and P955HR (physical variant of P950HR).
  13. I am looking for information on the procedures to replace the integrated BIOS Logo on several laptops. The model numbers are the P650HP6-G, and P650HS6-G. In the past, we have been able to replace the logo on those BIOS's using an Asus BIOS Logo tool, and Secure ROM Signing tool successfully. However, with newer BIOS updates, I have been getting an error message "18-Error: Secure Flash ROM Verify Fail." So I have been staying with older BIOS versions instead of trying to force a bad flash. The P650HS is still using a .BIN for the main BIOS flash file, however, the P650HP6-G has changed from a .ROM to a .8M or .04 file, depending on which method of flash used. One file size is very different from the other (most likely because of a combined ME and BIOS flash code in one file. The trouble is, I am unsure whether these are to be seen as a normal BIN or ROM file, just named differently, or as a completely different type of file. I am using the BIOS flash file that is used only for the BIOS, which should be free from abnormal code arrangement for multiple components. I am in need of an appropriate Logo replacement utility, as well as the digital signature utility for Secure boot. If there is the matter of having a valid key assigned to the company for this purpose, I can present that to my managers for their follow up.

You may if you can, I will post a copy in the parent forum.
  15. I am looking for some software that I can run on laptops to verify the correct operation of the Fingerprint Reader. We are installing the basic drivers so that the device is operational, but we are not installing the security suite that comes with it, unless specifically requested by the customer. When we first carried the Clevo W150HNQ, the software suite allowed the testing of the fingerprint reader without creating accounts or registering finger prints in the Demo Mode. I was wondering if there is a small program that I can run, without installation, that will show me the input from the fingerprint reader each time it is use, so that I can verify that it has not been affected during the disassembly, painting and reassembly processes. I have been searching for a program to do this for a few years now, and have still not found anything that even comes close (except for that initial version of the security software, which has been verified to be insecure).
