My laptop wouldn't start unless I chill it in a refrigerator first...

I have a sony laptop and last summer its fan area was getting very warm and shutting down.  I had let it cool for a couple of hours to start it again.

I opened and removed blockages from cooling fan area.  Now, it doesn't shut down (summer is not here though).  The problem I am having is when I turn off and turn it on again it doesn't start (hard disk doesn't kick in).

As a remedy, I put it in a refrigerator to chill before it starts again (on button will be on but noise wooosh when the hard disk start is missing because hard disk doesn't start at all when it is not perfectly cooled or it hasn't been use for a day or two).

- Is it possible I haven't properly reinstall some wires after I cleaned up the cooling fan area?

- Is it possible my hard disk is dying?

- Would this chill process harm my laptop (some part inside might sweet and the moisture could damage some sensitive parts)?

- Is it possible some connection doen't allow current flow unless it is cooled to make the connection possible?

Thank.

1-Is it possible I haven't properly reinstall some wires after I cleaned up the cooling fan area? --->unlikely, but possible

2- Is it possible my hard disk is dying?   ---> there is undoubtedly something wrong with your disc

3- Would this chill process harm my laptop (some part inside might sweet and the moisture could damage some sensitive parts)?    ---> Not to my knowledge, if you put it in a sealed plastic bag.

4- Is it possible some connection doen't allow current flow unless it is cooled to make the connection possible   --->> this is called a bad contact

answers, remedies :
1- checkand recheck all cables and plugs
2-to test, hook it up to another laptop, or PC (with a2.5" to 3.5" cable adaptor)
3-as said
4-same as 1-

Um, i hate to break it to you, but you might want to replace your HDD soon. "sticking a hdd in a freezer" is one of the methods of getting a non-working hdd working again for a short time.

Remove hard disk and reinsert it again. RUn Spinrite from www.grc.com and it will try and fix any problems it faces. Also its possible that while ur system was getting hot earlier some capacitors etc might have gotten damaged on the board. Use the hard disk tools below depending on ur manufacturer and check for drive integrity.

CHances of the hard disk being bad are high and it doesnt matter weather u seal it in a plastic bag or otherwise the air inside the laptop will cool down and when u power it up it will condense for sure leading to the possibility of the circuits on the laptop getting fried or shorted out. Also the heat+cold proceedure will weaken the circuit board inside the laptop lkeading to total failure one day. Dont try this, its a bad idea.

U said its a SOny LAppy.... did ya call them.. what was their response ??? If this is not an oldie.. u can get it serviced if within warranty for free... and even get it replaced if there is a Hardware problem.

Dying HDD is the biggest probability but cannot rule out other probs.. get  a converter for ur Lappy's HDD and connect it in a Desktop to see it that works.. if u get the hard disk working in a PC then check if ur HDD Is getting power in the Lappy... U didn't tell if u see anything on the display or not...

if u r not getting any display then probably somethin gone wrong with ur MoBo...

Thank you all for your responses.

Re:> Is it possible my hard disk is dying?  

I whishfully think this is not the case.  When it is on (computer is booted) works fine and there hasn't been much us or abuse of the hard disk drive.  Also, this is not a very old computer.

(Have no warranty and want to look at all possibilities before sending it to soney).  Cleaning fan area took me about 15 minutes where it would have cost me a couple of hundred dollars if I had serviced it by Soney).

Now-a-days, instead of turning it off or pressing on hybernate key, it leave it alone until it hybernates automatically.  Then, by click of any button it comes up just fine.  

When I start the computer (after chilling it and getting it ready to be served. LOL), power light comes up, a beep is heard, 2 woosh sounds are heard (thes sounds belong to fan and the second one to the hard disk drive).  The second woosh sound start as HHD light lights.  After the second woosh sound, Soney logo apears on the screen and the rest is fine.

But, if it is turned off (after say 5 minutes of work), the power light will come on, beep and the first sound will be heard but no HHD light, HHD woosh sound will happen.  The screen will remain black from that point on.

It seems to me, five minutes or some of the laptop work is producing heat and causing expansion (or extension) of some connection and making it a bad connection until it is totally cooled off and it has shrunk to its original size.

Obviously, such a connection is used on the start-up of the computer (similar to car's switch-key operation).  

I deally, it will be good to eliminate this possibilty first.  Could this be true in my laptop case?

Regards,

Mike

Having said all this, I realize HHD failure is like a hearth attack.  I will not let one know when it is going to fail.  It just fail.

If you can ever get a pulse again, I highly recommend you BACKUP everything important on the drive somewhere else!

The hard disk is failing for sure. Its having trbl initialising properly. Once initialised however it doesnt need to do that again and works fine.

When u power it off and power it on again it needs to init properly. Having said that if u leave ur system ON all the time chances are high u wont face any failure however Laptops are not meant to run continously and need rest in which case its entiurely possible that u shutdown ur systema nd then the hard disk doesnt init properly at all.

Its upto u to take a chance or not. If u work on importaant data then make sure u keep takin everyday backups just in case the HDD fails one fine morning.

Hi Dan,

Re:> Use the hard disk tools below depending on ur manufacturer and check for drive integrity.

My HDD is HITACHI_DK23EA-40; I wonder if you have could privide a link or advice me how to search for it?

I am not very good in hardware matters and don't have tools to properly remove the HDD withouth damading something else (cleaning fan was something I took the chance but very hesitantly).  

So, I will remove and reinstall the HDD (as you have suggested it before) after making sure the problem isn't elsewhere.  I want to do "Drive Diagnostics" first and possiblly later remove and reinstall the HDD if necessary.

Regards,

Mike

you can look in device manager, under hardddisks, or use Everest to identify it :
