Hi!
Just tried to add Crucial ram to a used Precision M6500 Win7 Laptop - 2.8GHz core i7 *GB SP1 on EBay last week. After taking advice from Crucial tech this laptop will no longer boot.
Apologies for the long explanation:
Working machine came with 8GB (2x4) of Hylinks Ram. I added 8GB (2X4) of Crucial memory under the keyboard of the machine. The machine would not boot. Pulled memory from all four slots. Put one stick of Hylink and one stick of Crucial in battery side slots to see if they work together there. The machine booted windows. So I put the other Hylink and Crucial sticks under the keyboard. The machine did not boot.
I called Crucial. Tech told me to pull the cmos battery. Wait 15 minutes and plug it back in. This is were the real fun begins!
Now the machine won't boot windows under any condition.
I pulled the the additional memory out from under the keyboard. The machine runs the memory test and blue screen flashes on and off in a split second. It goes into startup repair mode. And ends with the following report every top I push the start button:
"Windows failed to start. A recent hardware or software change might be the cause....
Launch startup repair (Recommended)"
Start up repair does not work. The machine will not boot Win7 with either 8 or 16GB in place.
So it seems pulling the cmos battery is at the bottom of this. But for the life of me I can't figure out why?
The following are things I've tried to get windows to boot that have not worked:
1. Replacing original Hylink with new Crucial ram. And tried swapping sticks and slots.
3. Loading default settings in bios (I did remember to reset date)
3. Pulled and reinstalled the cmos battery several times.( Made certain the date was set correctly each time.)
4. Did a system restore
5. Ran startup repair every attempt to boot.
6. Restored the MBR successfully (FixBbr - Fixboot - Rebuild Bcd).
7. Ran and passed a hardware diagnostic.
I am still failing the startup repair routine after the initial memory test at boot. What I am missing?
Help!
