Hello all,
This is my first post here and i am wondering if you can give me a hint about the following problem.
I have the Vaio VGNA 397XP with 1Gb Ram (Processor is intel centrino 2 running in 2GHz with 2Mb cache), ordered in May 2005.
The general performance of the laptop was great until the last 3-4 weeks that some strange behaviour started.
The performance of the laptop suddenly without a reason drop down for 10 to 30 seconds and then the computer recover back to normal speed.
In this period i check everything without notice any problem on software and hardware. The last 2 weeks the problem was more intensive and the computer stop recovers anymore.
I download and install the CPUZ application to check the timing and the processor speed because i was a little bit confused of the above situation and i noticed the following:
1. The speed of the processor was not on 2Ghz but on 800 Mhz (in the Power management the option "Always on" is selected)
2. When one application or game running then the processor jump to 2GHz and after the load procedure completed the speed drop down to 800 MHz or even worst to 500 Mhz and in that case is also droped down the bus speed from 533 Mhz to 200Mhz.
3. Even when i change the Power scheme to adaptive and performance the previous are not changed
4. There is not diference if the laptop is cool or hot.
5. The laptop is really hot in some cases, There is really high temperature on the top of the keyboard (but is not so high as it was before the problem starts)
Is it a hardware problem?
I appreciate any help or hint.
Thank you in advance.
