Locked

Latitude D600 - intermittent freezing and power up issues.

By dollsteak_2002 ·
I have a Dell Latitude D600 that has recently begun to give me a major headache.

Out of the blue the laptop completely froze while running an application that has been used regularly. After a hard shut down, the laptop froze at the Dell splash screen...another reboot, it freezes halfway through the windows load screen. Yet another hard shut down, and the lights come on, then go off with only the Caps lock button flashing for about 10 seconds...takes about 3-4 attempts to get the power back on. System finally loads into Windows, stays on for about 15 minutes and locks up again. I tried going into the BIOS, it freezes 3 out of 4 times. I was able to get into safe mode once, and it was ok for the time that I was in there.

I have swapped about the memory, tried booting without a hard drive...same thing. I have checked that the fan is working, and although it does not come on at system startup, it does come on shortly after. I have run the Dell PSA diagnostics with no errors.

Any ideas would be greatly appreciated. I am guessing that it's the motherboard, possibly the CPU, but would like to explore all avenues before replacing either of those.

D600 BLINKING CAPS LOCK SOLUTION :)

by michael In reply to Latitude D600 - intermitt ...

Problem:
D600 Blinking Caps Lock.

Solution:
Do not lock down the memory modules.

Cause:
In "some" D600s the plastic surrounding the bottom pins of the memory socket extends higher than it should. When locking the memory into place this causes the memory to rise away from the pins.

Action:
The chassis' memory cover plate needs to have that black insulation on the inside. Place the memory firmly in the socket(s) but do not lock them in. Apply the plate and screw it in tight. The plate will hold the memory tight enough.

Dell D600 was freezing up after five minutes. Power off then back on..it would shut itself down. Read Michael's post on the memory modules and at first thought...man that's wierd...but tried it. Lo and behold the lapper works again!
