T21's with problems

[elportugues]

I need to repair three T21's with the following problems:
1-Message 0175 CRC1 Bad
2-Does not recognized the Hard Disk
3-Try to turn on with no success

I have tried the three of then with different batteries, CPU's and Hard Disks, but unsuccessfully.

Any help will be appreciated!

1. Fixable (see your PMs), but not easy or cheap.

2. Check the HDD seating first - could be the pins aren't properly aligned. If you've already tried another HDD, check the BIOS to be sure the HDD is listed as a boot device. Try booting a HDD diagnostic disk to see if it can deal with the HDD. I think more information would be required to go further (what do you mean "does not recognize"?)

3. Check for "BOD" (Blink of Death) with the search function and see if that reminds you of what you see. If it does, the only answer is a new mainboard. Otherwise, describt the problem in detail and maybe someone can make other suggestions.

Thanks for your information on the 0175 problem.

On the 2nd. one the message that I received is that no hard disk is attached.

On the 3rd. one (One time I was recharging the battery and did it too long and when I tried to turn it on again. It did not power. ) It Shows a blinking, but does not turn on.

Thanks again!
