This same effect was noted after repairing a few desktops where the owners didn't put heatsink compound on the heatsink. After it was fixed some owners complained the heatsink was running hotter.
All is as it should be. Since it's not busted and as it should be, I'll stop here.
Hi There! Off lately, I got my HP 530's LCD screen replacement by paying money due to some Warranty issues. Now, the HP Service Centre in Mumbai has done the LCD Screen replacement and says that also the cleaning & servicing work has been done. Once I bought my HP 530 Laptop back home, I started using it and noticed that my laptop now starts getting heated from the bottom at much faster speed within no time than it used to before. Also, when I ran a tool known as "Intel Processor Identification Utility" on this laptop, I see that System Bus has been reported to being overclocked. So, I went to BIOS and got all the setting back to default by Pressing F10 key within BIOS. After this, I restarted my computer and again ran the same utility but this time, it reports that the System Bus is now fine and NOT Overclocked. However, the heating issue underneath still continues.
This heating is immensely happening exactly in an area under the ventilation fan and at the side compartment near to Ventilation fan from the bottom of the laptop. Now, I believe that this area should be the processor compartment. Therefore, I checked out the bottom Ventilation area (Circle Shaped) with the torch light and found that the Fan is not moving at all even though the laptop is getting heated. However, when I talked to HP Service Centre, he says that the Fan rotation is an automatic function which will only rotate once the system starts getting heated and what I am experiencing at the moment is Normal heating but I don't accept that since it is heating much more than expected.
And it is much wired to accept that when in Desktop PC, the moment the computer is Turned ON, the Power Supply Fan starts rotating than why not the same in HP530 Laptop. Also, HP service centre mentioned that keeping the laptop in continuous charge mode can also increase the heating but I believe that once the battery gets charged to 100%, then there is an automatic "Cut Off" and the laptop should work directly work on Alternate Current and I used to keep it connected before as well in last year but such heating never used to happen. So, I have a question to ask here:
a) When a fan isn't rotating in a laptop from the side and down ventilation, than how safe is it to still continue using the laptop? Can it affect the CPU & Motherboard?
b) It is true that once the battery gets charged completely, the Power cord should be disconnected or is it safe to continue on the Alternate Current (AC) as well? Can working on Alternate Current damage the laptop's Motherboard, CPU or any other compontent?
Kindly help me out please.....Thanks!
