Latitude e6500 booting problems
Hi all,
My Latitude e6500 has started to fail booting intermittently, now more frequently so it has become pretty unreliable and I love my laptop so I would like to fix it if possible. When I press the power button there will be sounds heard like if the fans and HD want to start, but then it stops and it stays in a situation were the num lock key is blinking, and the caps and scroll lock lights are on. Nothing comes up on the screen during this failed attempts to boot. Sometimes there seems to be an association between this happening more often when the computer turn itself off (sleep) than when I turn it off. The mystery for me is that it does it intermittently so I'm hoping it can be fixed without something serious like needing to change the motherboard.
I'm sure this has come up before in the forum, but I truly spent more than an hour browing around and found other versions of blinking lights, not this. perhaps I didn't use the right keyword? Your help will be greatly appreciated. Regards. Hernan

Hi,
The flashing on on led code points toward the CPU connector on motherboard, but very rarely the issue can be memory.
Can you try reseating the memory and keep it under observation.

Ok, I will do that and report back.
Thanks for the support with my issue

I tried but couldn't find the instructions for conducting the memory reset procedure as you recommended.
Could you kindly point me at the instructions on how to do it?
Thanks

Hi,
Please follow the video on how to remove the memory . Once the observation is done, put back the memory in similar fashion and let us know.

question have you ran a full stress test on your ram. I've found that most of my random problems tent to lead to memory issues.

Thank for the link to the memory reset procedure, it seems pretty straight forward. With regards to the question I'm not sure that I know what a stress test is, but before writing to this forum I did run the diagnostics program offered by Dell which I believe includes testing the RAM and it passed.
The thing that actually intrigues me is that my understanding is the processor will try accessing the memory AFTER running CMOS and if that is so, I should be able to see the BIOS/CMOS opening page at power on before the system crashes, which doesn't happen. The laptop either starts normally, or doesn't at all (totally black screen) and does a few noises followed by the blinking num lock and the lit up caps and scroll lock. With that said, does it still make sense to try the memory thing, or should I rather try removing and reinserting the processor (? do you have a video for that?). Very appreciated!

Hello,
I definitely would not recommend removing the processor, as that would void the warranty (if the machine is under warranty) and might lead to further issues at hardware level.
We are giving it a try by reseating the memory (only if you feel comfortable).
Your can try updating the BIOS, just in case , and keep the machine under observation.
Regards
