Question about Sony VAIO VGN-A790 Notebook

2 Answers

My Vaio VGN-A790 runs really hot. Now it's also running really slow. I ran a utility called SpeedFan. It says the effective clock rate is 688 Mhz s/b 2Ghz. I'm thinking the processor fried. I first noticed video performance issues but that could be attributed to the clock rate too, right.

    I disassembled the unit yesterday and blue out the dust. I checked the fan and it turns. Seems like it's not turning very fast. Not really loud enough to hear. the cooling looked a bit on the cheesy side to me.

    For several years, I've had the laptop docked and KVMd with another PC. The high temp isn't so noticeable. I just noticed that loading a website takes forever, and videos? no way. the graphics soon start freezing or are really jerky while the audio plays on.

    Can I get a replacement video chip (I guess that's what's heat sinked next to the processor.

    appreciate the advice

The overheating problem is the primary source of all the complications you are seeing. The reduced clock speed may mean that the processor is already hit. However I suggest that you open the back cover of the laptop and clean the heatsink(A copper wire that goes from processor to infront of the coolant fan. Make sure that nothing is preventing the airflow from the fan to heatsink. This page might help you with the dis-assembly

No, the speed is normal, since the data speed (2GHz) is equal to the effective clock (688MHz) multiplied by the data rate (4).
The video problems are caused by the heat - memory corruption. Check the cooler and the fan of the processor for dust (clean the inside fully) and make sure in Task Manager that no process is eating power unnecessary, slowing the pc down.

    If the temperature and the image on the display itself are ok then the problem is software, not hardware - something is eating processor power and messes the settings. 



    My guess is that your system is suffering from software rot - the most efficient way to fix that is to reinstall.

For the sound effects to work you'll need to download SC (Starcraft) Sound Edit Utility.

Open up the utility and then open up file Sfx.agg found on a standard installation here C:\Program Files\Sonalysts Combat Simulations\688I Hunter_Killer\Sfx

Select all the sound files and extract them and you are done. If curious for me the sound files ended up in the compatibility files.

Blank (dark) notebook screen after hooking up digital ext monitor


I notice a difference in the setup of the two monitors, have you installed the correct driver for the new screen?

Try F8 on startup to get into safe mode, this should allow you to use the default VGA screen, and to reset the correct monitor drivers.

If less than 90 days, it is under Sony's full coverage. Usually the fan runs intermitantly. Check that air paths are not restricted.
