DELL 6400 pc card slot issue

I have a new 6400 with Vista and I am trying to use a scansisk 6-1 card adapter and the card slot does not even recognize that I have inserted the card. Any ideas. I tried to find out if the reader is vista compatible and I can not find anywhere that says it is not compatible. Any help would be welcomed. mark

Re: dELL 6400 pc card slot issue

Check in device manager via control panel, then click classic view; that the pcmcia card bus controller is present in the list and install the card reader driver if one was supplied, if not then there is no need for a driver and it must be a fault with the pcmcia driver.

Dell Inspiron 6400 wont recognize new battery

Well often batteries from 3rd party manufacturer do not work in some laptops, see even the batteries have a "Chip" in them identifying them. Also sometimes these batteries are just no-good. or arrive flat, too flat to be charged up via the supplied charger. Anyway hopefully none of that applies and this will work. Now Turn PC OFF, put battery in unit. Now plug in wall unit, then plug into the PC, now leave the PC totally alone for at least 3 hours. Now the unit should work. Now how we tell where the problem lies is like this, Turn OFF, take out battery, now plug in the wall adapter, now the PC should work Fine like this. Now remove wall adapter, and insert the battery, the unit should go on this.. ONLY of course if charged. Now if when plugged in there are problems, it is more than likely, that indeed the battery is faulty, in some way.
These links below detail what steps to take to remedy any situation. The 2nd link is great.

Computer won't accept a compatible replacement battery for Dell Inspiron 6400

This could be due to a defective battery even though it is new. These batteries are what are called smart batteries. They have circuit boards mounted inside the battery pack that aids the computer in recognizing the battery as well as sending functional information to sensors in the laptop about battery health and performance. Try re-installing the old battery and see if it recognizes the old battery. if it does, the contact the company you purchased the battery from and let them know the problem. If the computer does not recognize the old battery anymore, there may be a problem with the charging circuit on the motherboard or the power adapter on the motherboard.

I Have a Dell Inspiron 6400 with Vista and It seems I am getting a memory or motherboard issue as the Caps and scroll lock LED's flash when I switch on and hold the FN key. Basically the laptop is not...

Getting the motherboard fixed may not be a cost effective solution.
You can salvage some of the components to use eg. the RAM and the hard disk.
Put the hard disk into an USB hard drive adapter case and use it as an external USB hard drive for backups etc.

Driver or Hardware issue

This could be a problem with the external attachment, but it sounds more like a compatiblilty issue with Vista. Check the compatibility of the devices and their drivers, and get back to me.
