Hi

fixing a dell lattitude cpx notebook . Its hard to turn on, usulay takes three goes to get it to start. Very slow to post and once past wont boot to xp normally or in safe mode. Checked the harddrive , put it into a tower and its boots up fine there. Replaced the powerboard but still has problems startting up, slow and not booting fully. I guess its the motherboard but wondering if I have missed something else?

tried it with battery/without, without cd drive. Always freezes in safe mode and normal mode. tried it with xp install disk. freezes after loading all the drivers. tried a bartPE disk again freezes and does the same with a linux standalone disk. Only things I can get to run are a couple of emergency boot disks with partion magic, spinrite and memory tests.. these all run fine just not full blown OS

thanks

Ric

Check your memory. Remove the sticks then add only 1 stick at a time.

Which BIOS version do you have? You might go to www.dell.com and get the latest BIOS update.

I believe the CPx has a diag utility built in.
Hit Ctrl-D to go into it.. I think.. If this doesnt work, let me know. I have a couple of CPx's myself and would have to get them out and try it myself to get the right sequence.

ctrl-alt-d goes into the HDD diags. Press it while the dell splash screen is posting.

The bios on mine is A16

Oh, one other things about the CP series..

Check the screws on the bottom of the case.
Those little suckers have a way of coming loose and cause all kinds of problems

greetings

can you get into your bios and check the temps for awhile?

laptops are basically hot plates with a wimpy cooling fan or fans the size of a silver dollar at best. and the heatsinks are scarey .

can get into bios but it does nt report any temps or voltages. . been running hardware tests all morning and it runs fine (everything is loaded to a ramdisk) , just cannot get any xp disks to run. I'll take the drive out and put it back in the tower see if updating xp helps .

How much memory do you have in the laptop? Anything less than 256meg is going to make for a very slow bootup.

Have you run CHKDSK and Defrag on the drive?

Dell BIOS does not report temps You would have to get Everest or Sisandra.

One other thing, you say it takes 3 goes before it turns on. Do you mean it takes 3 times pressing the power button?

If you dont mind. PM me the Service tag number and I can access Dell and see what the system configuration should be.

ran defrag and chksidk last time it was in the tower.. badly fragmented but diskeeper sorted it out.

yes usualy takes three goes (it will start then shut down, 3rd try completes post) to get it to start. that why originally i thought it was the powerboard, replaced that still no luck. So do have a new motherbaord on the way but wanted to check if I had missed something.

Off topic but... That's not always true. The HSF in my acer is full copper and finned like crazy. It dissipates heat from the A64 heart beautifully and NEVER causes it to overheat.

As for the Dell, it may be a failing HDD controller. A completely bad one would prevent booting completely but a failing one may partially work. Also, the CPU may have just tuckered out. if the HSF wasn't doing it's job then that could have greatly contributed to it.
