Sony Vaio PCG-K86P laptop


Having a problem booting my Sony Vaio PCG-K86P laptop, power indicator lights up but screen does not display anything. Have tried Sony's solution ie., unplugging AC adaptor, removing battery leaving off for about 1 min then inserting batt and AC power. This does not solve problem. I found that removing battery and switching on using AC adaptor power did work and I got my screen display working.

However this does not always work, can you please advise.

My Sony Vaio PCG-K86P laptop is three years old and just over 24 months ago had a new motherboard installed, more recently had the Laptop checked out by an IT Service Techo and he gave a good report like saying it had at least another years life etc.

Appreciate if you can advise what might be the problem and point me in the right direction.

    Hello, I have a serious problem with my laptop. After a period of 30 minutes I start my laptop, if I shut the computer down I have to wait another 5 minutes before I can start it up. If I don't wait that long then my display will not work. I have no idea why it does that, but it gets very annoying. To top it off though, I cannot install any OS on it. Help is much needed. Here's something that happens when trying to install windows.

    Hi. My laptop his getting very hot. Its a PCG 5KFP model. Previously, the only way it worked was with the bottom (back, cooling units) panel removed and raised up for air circulation. I have had the cooling units checked and now it does work normally when plugged in. The problem is the battery runs out within 2 hours, even on power saver mode, and the battery and cooling units get very hot! Is the first step into finding a solution replacing the battery?
