I have a Toshiba Satellite P305D-S8903 at my home which I use for internet browsing and text editing. Many times it happens that I am unable to use the laptop for many days in a row. I just cover it with a cloth and use it after a long period of weeks. When I start it after weeks, the LEDS on my laptop that indicate the battery, activation and deactivation of Num Lock and Caps Lock donít work. But the laptop functions properly, there is no problem in its working. I asked my friend about it and he said that maybe CMOS battery must be draining out as I never power my laptop for many days. But now for some couple of days when I am using my Toshiba Satellite P305D-S8903 for long time, it is crashing randomly at random times. After startup, the laptop sometime remains switched on for forty minutes while sometimes crashes in five minutes. Today I ran the Toshiba Diagnostic program to find if there is any problem with the installed operating system, driver or any other software related issue. But the diagnostic program didnít find anything wrong with the software part in the laptop.
Now I thought that the problem must be due to some malfunctioning hardware. My first suspicion was the mechanical lid switch. So I tried opening the cover of the laptop. At this time, I discovered that Toshiba Satellite P305D-S8903 doesnít use mechanical lid switch. Instead it uses, magnetic lid switch which holds the body so tightly that it is very difficult to open it. I am getting a feeling that the magnetic field created by this magnetic lid switch must be affecting the working of the laptop. I have disabled the ACPI lid switch and rebooted my laptop, but still nothing has changed. The laptop still reboots randomly. The battery also seems to be working fine without any problem. Can someone help me solve this problem? I have mentioned all the symptoms and problems faced by my laptop. Can someone shed some light on the cause and cure of the problem?
