Card reader not working

Advent / Ert2250

Specs: Windows Vista
Hi. I just bought a refurbished laptop. Advent ERT2250 with W.Vista:

It has a 4in1 Cardreader, but when I put in an SD card nothing happens (I haven't tried with any other card). There's no card reader drive on Computer, either with the SD card in or out.
In Device Manager there's "SDA Standard Compliant SD Host Controller" enabled, with updated driver, and "working properly".

I don't understand it... any thoughts?

By the way, the same site you pointed to says your card reader may be an 8 in 1, not a 4 in 1.

"In Device Manager there's "SDA Standard Compliant SD Host Controller" enabled, with updated driver, and "working properly"."

I have not used Vista yet but many things are the same or similar to as in XP.

That's probably got nothing to do with the SD card itself. You don't normally see anything about the type of card you have plugged in Device Manager. You often don't see anything about "reader" in Device Manager either.

"SDA Standard Compliant SD Host Controller" drivers are apparently generic drivers for several different card reader chips - they may read other cards in addition to just SD cards - on a laptop the chip is usually built into the mboard - you get the drivers from the operating system automatically, more likely in the case of Vista than XP, or after the mboard drivers for the operating system have been loaded. The fact the device appears to be working correctly in Device Manager probably indicates the card reader chip is being detected, but are there updated drivers available?

Depending on the particular card reader, you may see a drive letter in My Computer or Windows Explorer for each of the physical slots in the reader, whether it has a card or cards plugged into it or not,
OR there may only be an additional drive letter show up when a card is plugged into the slot, for each card if more than one is plugged in, if it's partitioned and formatted, and if Vista recognizes it because it's partition and any data on it is not damaged.

If the card reader is working, when you plug in a memory card, if the card is recognized, if no other cards or flash drives have already been detected, you will see an icon that's a grey rectangle with a green arrow on it show up in your taskbar lower right - if that icon was already there, if you click on it the card you plugged in will show up on the list of devices available as a drive letter you can select to stop accessing the card, if the card is detected properly.

You don't normally see anything about the type of memory card you have plugged in, in Windows, unless the drive has a volume label that mentions that, which is unlikely.

If the partition and or the data on the card is damaged, you probably won't be able to read it in any card reader or in the device it is used in otherwise, if applicable.
(if the card reads fine in other readers on other computers, or in other devices, something else is wrong).

The most common way the partition or the data on a removable data storage device gets damaged is by you NOT clicking on the grey rectangular icon with the green arrow on it, and Stop accessing the device you are unplugging., when the computer is running and you are in Windows.

Does the card have any data on it?
If it doesn't has it been partitioned and formatted (they come that way when new)?

Does it work in other readers or in a camera or whatever?

Sometimes you can plug in a memory card into a card reader the right side up or upside down - it usually goes in farther when it's the right side up - it only works when it's the right side up and in all the way.

If that doesn't help....

If it's built into the laptop, someone has probably neglected to load the drivers for the reader.
Look on the website of the system builder in the availble software and driver downloads for the model.
Are Vista drivers available?

Sometimes devices built into the mboard are not detected until after you load the drivers for the mboard, especially in the case of a laptop. Are Vista drivers available?

Whenever you load Windows from a regular Windows CD (or DVD) from scratch, after Setup is finished you must load the drivers for the mboard, particularly the main chipset drivers, in order for Windows to have the proper drivers for and information about your mboard hardware, including it's AGP or PCI-E, ACPI, USB 2.0 if it has it, and hard drive controller support. If you have a generic system and have the CD that came with the mboard, all the necessary drivers are on it. If you load drivers from the web, brand name system builders and mboard makers often DO NOT have the main chipset drivers listed in the downloads for your model - in that case you must go to the maker of the main chipset's web site, get the drivers, and load them.

If you're not sure whther the main chipset drivers are loaded, in most cases you don't need to un-install any previously loaded main chipset drivers, and installing them again if they are already present does no harm.

If it's on a reader on a card in a PCMCIA slot or an ExpressCard reader, it probably didn't come with the laptop, and you need to find the drivers for the card.

If you're plugging a card into a card reader that plugs into a USB port, the reader may not work properly or may not even be recognized.

Some older readers won't read high cap sd cards. Try an old mmc card. Or get a new usb reader.

"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

"Some older readers won't read high cap sd cards."

Good point. E.g. 4gb or greater, or maybe even less.
If you can't find that info where you find the info about your model, if you can determine which reader chip you have with some program, or otherwise, you can look up the specs of the chip.
