  1. A loose connection can cause this, there is usually a separate cable for the Keyboard back-lighting, and a partial connection can make odd behaviors. I have also seen the power supply circuits for the Keyboard Controller chip malfunction, causing interesting behaviors. Unfortunately, I am not familiar with that particular model of Laptop, and cannot provide more insightful information to how that model runs.
  2. "I am ok with what I have, bit if the prices come down to an affordable level, I would be open to obtaining an RTX 40 Series." For now, a GTX1070 is serving the needs well.
  3. I'll have to look at the information I have at work, but from what I can remember, the HM's were only compatible up to the 680 or the 785.. i think. The 9 series drew too much current, needed more thermal dissapation, and all the video cards need Vbios matched to Main Bios and EC Bios, or you will get the thermal management error and forced shutdown. I'll have to get back to you tomorrow though.
  4. Yea, that'll stop it from posting. There are particular behaviors for both that will help you distinguish what is happening though. Also, a visual inspection of the board is always good for shorts, blown components and such. Depending on the short, the system will either not turn on at all, flash on for a very brief moment, or turn on, and then turn off after a specific time frame that is not related to thermal shutdowns, or unresoved POST procedures. The sheer number of possible problems in either category make it very hard to point you into the right direction though. reflashing a BIOS from external programmer is not for the feint of heart.
  5. I can't give you concrete answers to the video problem, but I do know that the Vbios of the video card is matched to the particular configuration of the system BIOS's of the laptop model they are put in. I believe this has to do with the ME monitoring temperatures and running fan speeds, The BIOS for which display to put video to by default and what the correct display modes are, as well as coordinating the Backlight power with the GPU and power delivery. That's mostly my speculation based on behaviors I've seen in the past. As far as the memory goes, I believe that model has four slots for RAM, two on the bottom, two under the keyboard. Try different slots to see if some work better than others, and run Memtest86+ on each stick individually to see if one of the sticks of ram is less optimal than the other. Sometimes the sticks of ram test good, but don't play well with each other, and one, or both need replaced. Sometimes that model takes a good two minutes before it finally resolves an acceptable RAM timing solution, reboots and posts normally, so be patient with it. (this is usually only when there are issues with ram sticks agreeing with each other.)
  6. God to hear you found the major culprit. Those laptops always ran pretty hot, for all the versions of them that I handled. I did not venture into alternate BIOS's, (not something my company does), so I can't speak to how that might help. Dust is definitely the arch nemesis of high wattage systems.
  7. Sounds about right for thermal fatigue.. Old GPU fought well for a long time, but got too hot at some point, and something inside the chip was damaged. I can still run, but wilts under pressure. (As it happens, this laptop I'm typing on is suffering from about the same issue... I can play most games though, it takes a heavily rendered scene to get the device to drop out of sight and crash the OS.)
  8. I think this is an interesting mod.. however, I don't see how the water can cool the laptop more efficiently than the heat pipes. The only benefit that water would bring, would be to have an external reservoir for more thermal mass to sink the heat to, and the ability to increase the size of the radiators. In that it appears that these are all internal, then I would expect they are a down grade, in that the radiation surfaces remain the same, but the thermal transfer is slower through water than a state changing vapor.
  9. I would definitely say that the GPU died. Would those games be likely to have simple enough graphics without an FPS limit that might make the GPU generate excessive heat and die from over heating? This is not an unknown end to a long time behaving card, after a long time, they will get too hot and cook too much, and then never turn on again, or if they do turn on, they are damaged, and will either turn off under load, or show graphics corruption, depending on where the damage is at in the chip. The fans spinning up is a common symptom of the EC BIOS looking for a temperature signal from the Video card, and, not seeing one, turns the fans on high by default to avoid letting something over heat before doing an emergency shutdown. Similar will happen if there is no reported Fan speed on all inputs, except it will flash the NUM/Caps/Scroll LEDs in relation to the position of the fan in the chassis, to indicate which fan it's sensing troubles with.
  10. Exchanging video cards in the slotted systems is usually hampered by BIOS support primarily. Secondarily, there may be power differences in the slot, with wiring changes,and I believe the slot key will change in relation to these differences. As you go up in the GPU levels, the power draw changes, and there are additional power cables to connect, using different connectors. There are compatibility possibilities, but don't expect it to be straightforward. On the systems with desktop CPU's, they do have sockets you can drop different CPU's into. I haven't seen a socket-ed mobile processor in a while though, so I'm not sure how prevalent that is these days.
  11. That sounds like the battery has been dead for too long, and is now unchargable. LI-Ion cells need to have a trace voltage in them to be charged. There are ways to possibly recover them, but it is unsafe, and the results could be anything from not working, to bursting into unstoppable flames. The best thing to do, is to source a replacement battery for it. Some battery places are capable of rebuilding the pack with new cells, but it costs a pretty penny, and may not have the capacity it used to. Gah, just saw the last line of your post. I guess you have a decent handle on some of the recovery possibilities. Proceed with caution, at your own risk.
  12. I do not see how these posts are relevant to the discussion in any way, topic, context, or subject alone. I would regard them as spam posts, since both users are new, they are both on the same topic, they are both at 1 or 2 posts. The only flags I see, are red.
  13. 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.
  14. 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.
  15. 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.
