DEAR MARK17 My medion MD 42100 aka MIM 2040 uses a "FSP GROUP INC MODEL NO FSP090-1ACD21 P/N.:40001966" MEDION SLAPPED A PAPER STICKER ON IT WITH P/N.:9NA0900101 S/N.:H00002046 D/C.:840212 OR D/C.:040212 (BEST AS I CAN READ) SPECS LISTED AC INPUT: 100-240 V~ 1.6A, 50-60 HZ ___ DC OUTPUT: 19.0V --- 4.74A MAX (90W MAX) (-)---C .-----(+) INDICATING POLARITY I would sure like one for the car. but medion wont sell me one??? The best I can do for mobile use is an a/c inverter with this thing plugged into it. I suppose this arrangement works but it seems kludgy. I hope this helps. Also be warned dont let the hinges get too tight mine is breaking along the hinges!!!! No solution for it except for maybe taking it apart before it breaks!

    There are 2 other POWER considerations:
    1. BEWARE the dc power jack is in a really bad location and very fragile and a pain to open up and solder. Solution preventative use a laptop pillow like the belkin cush top. Otherwise get
    a replacement jack from dcpowerjacks they were very helpful to me.

    2. The battery connection gets loose and causes machine to abruptly power down. solution use
    without battery. Mine works fine this way.

Close usually only counts in horseshoe throwing ..l The power supply really must be spot on...or better current rating.. see it's the Current supplied thats important as well as the voltage usually around 17v, but can B 12v, 14v, so ya gotta choose carefully, usually it is written somewhere on the lappy's bottom or by power socket. Most, all?, lappy's will work without a battery installed, they simply will not be able to use hibernate mode and sleep mode etc due to no battery but as long as the power is on it will be OK. Ensure your power connector is actually making contact with the length and center pin contact of the lappy's sockst they can be a devil for size..

    Also most lappy's power supply units put out more than 4amps.. st the voltage required..

My friends' Medion MT280G's VGA connector is not working properly. It has been pushed in slightly due to overuse and will only connect when you hold the vga cable in and to the left sightly. What...

The laptop must be dismantled and the bad VGA socket replaced - not a very complicated job but one that requires excellent soldering skills: the contact points between the socket and the motherboard are tiny and very closely packed. Take your unit to a repair shop.

Dear sir.where can I find the drivers for advent roma 2001

I would first try If you can't find drivers there, try this:

Some recent (2010) Advents eg Sienna, Modena and Quantum were manufactured by Shuttle. Drivers are not available from Shuttle
We have found some drivers for the Modena which probably has the same hardware as the others as Shuttle state it is their intention to standardise across the range of notebooks.
Chipset Intel 4 Series Express
Graphics Intel GL40
WLAN Realtek 8191SE ... 8191SE-VA2
LAN JMicron 260 Fast Ethernet Controller
Card Reader JMicron 38x Host Controller

For OLDER Advent Laptops/Notebooks and most Advent PCs are supplied by 'Medion' a German firm. Their website supplies ALL drivers, utils etc for your laptop by the Medion (MD) model number. This you will find on the back of your laptop and will usually begin with a MD- reference (ignore the Advent model number).

Stick this model number, or your serial number if you're using a PC, in here: and it will list all the applicable drivers for your notebook.

I have a Medion MD8825 power button blinks

Very possible a power supply. You are giving time for the power supply to cool off. So I would guess you are right about the power supply. They are not too expensive so you might want to replace it..Darren

I need a replacement keyboard for Medion laptop model no: MAM2100. OR MD 96327.I spilled water on the keyboard, some keys work, some don't. Want to replace the keyboard but cant find one to match. I HAD TO...

Check first for a spare on Ebay, that will be cheaper than buying a new spare, but parts for this model are difficult to find.

For example here is a RAM2000 keyboard, contact Medion to find out if it is compatible:Cybercom MD42792 Medion Ram2000 Replacement Keyboard

If you do not find a compatible part, call medion, they can supply parts and tell you what parts are

In US you can also contact Quanta that distributes medion parts internationally, they are locaed in US and ask part price and availability: Contact Us

Medion MD 7317 flashes colors after computer shutdown

That's what it's supposed to do. This is the monitor test to let you know that the monitor is working but it's not receiving a video signal.

if this is a desktop: Did you check the power supply? try to replace it with a new one

Laptop: Try to run the machine without the battery plugged in....straight with the adapter....If the laptop still's a manufacturing defect which should be replaced by the OEM.
