    Hello everyone, my G53 has been serving me well for the past few years, however lately it's been acting up. Random shutdowns due to temperature after graphics-intensive work (solidworks simulations) are common, running prime95 for even 15 seconds core temperatures jump to almost 100 Celsius before crashing. Now I'm noticing the power plug is ridiculously hot, I'm barely able to touch the metal tip. I had to uninstall all battery utilities as they would switch from battery to A/C power even with the battery removed. Since yesterday, I noticed in Throttlestop that my CPU would randomly lock it's clocks at 798 MHz, regardless of battery or A/C usage. forcing clock modulation and chipset clock mod to 100 does nothing to speed anything up. For reference I'm idling at 53-55 Celsius at idle. Can anyone diagnose my problem?

    Thank you!

    If you have removed your battery, of course your laptop is going to switch to an A/C power profile. What else is it going to do? Do you want it to shut down so you lose whatever you are working on? Most users wouldn't be very happy if that happened.

    If your CPU is hitting 100C after 15 seconds of Prime then obviously it is running way too hot. CPUs lose stability at temperatures like that.

    The G53 and G73 series have always had some issues with getting locked at 798 MHz. You need to disable BD PROCHOT in ThrottleStop to fix this problem. You better thoroughly clean out your laptop first. Open it up, clean out the heatsink and fan and replace the thermal paste if you have to. After you do this, post a screen shot of ThrottleStop while running something simple like a single thread of the built in TS Bench so I can see how you have it set up and what sort of MHz you are getting out of it.

    yea I butchered that sentence badly. What I meant to say was the utilities would try to switch FROM A/C to battery power even with the battery removed every few seconds. I blew out the vents a month or two ago, I'll take it apart soon and clean everything out thoughly.

    I cleaned everything out, however there were very few airflow obstructions; I only removed a few small pieces of lint in non-critical places close to the fans. Here are the results of the benchmark. Temperatures were reset before the start of the test. IHFZpV3.jpg

    Your thermal paste may be drying out in which case a fresh application would help.

    Use AIDA64 ( AIDA64 | PC Benchmark | System Diagnostics | Stability Test .) to confirm the matching temperatures as the correct temperature.
    If it's top off at 88C then it's fine, but if it's 94C then it's high.
