Hello,

 

 I have a Dell Latitude in  shop that has /is getting the best of me.

Here are the Specs

 

Dell Latitude E-5530

32 Bit

4 GB DDR3 10600S  ram 2 sticks

1 TB W D Hard drive

Running windows 7 Pro

 

Symptoms first:

Turn it on and it says press control C ----( I believe that is raid) the laptop does not use raid)

boot order is set to HDD then cd rom then usb

bios is the latest

 

 I thought it was a bios issue and dismantled the unit and reset the bios by removing the cmos battery and shorting the two pins together

I have tried F12 on Boot and boot from cd rom ..it reads it and will let me work off of cd..... HBCD ect

I replaced the motherboard and ultimately the HDD

I used Acronis to clone to a different brand new known good tested 1tb hdd

Now for the strange part... After replacing the motherboard it booted up fine and I sent it back with the customer. 1 month later it is back with the same symptoms.. Any clues?

My guess is it is dumping or trashing the mbr on the HDD.. Because I can boot to repair cd and command prompt then fixmbr it tells me it has a funky mbr and asks if  I want to change it I say y

then I do a fixmbr and it asks if I want to do it I reply Y then the thing works great till the next time down the road it decides to quit on him....

New motherboard...new hard drive...same symptoms...I'd be thinking PSU, CMOS battery, if it happened right away.

 

A 30-day interval between problems...doesn't figure, in my world.

 

But...it's a laptop and could be some other factor that's unrelated to my line of thinking.

Do the full diagnostic on the computer if you have not run it. I would also check what BIOS version the computer is running.
