Anyone own a Advent 7082 with the AMD Sempron 2800+ 1.60GHz Mobile cpu and 512mb DDR?

Phil2008 · 7 Dec 2007 at 16:13

Ive just won this on ebay for £84, when you turn it on it has these 3 lines on the screen, that im not sure if there ment to be there or not. Have I just bought a faulty laptop that cant be fixed?

I should get it sometime next week

Another question, why do laptops share the memory with the graphics card? cos it has 512mb of mem but 128mb goes to the graphics card, so it has only 384mb of mem really... Why? :confused:

screen faulty for sure will need replacing, but its still usuable in that state, shared graphics memory is far cheaper to make, sometimes you can lower it in the bios to free up more system ram

Screen kaput

Phil2008 · 10 Dec 2007 at 18:45

the screen looks fine cos if you look at the bottom near the lines, it displays a few numbers, and they display fine. So Im hoping thats its a loose connection somewhere or the graphics card needs reseating.

this is whats happened to your screen, this model does not have a separate gfx card

"TCP (Tape Carrier Package):

One of the most common functional failures found on LCD screens whether notebook or TV is horizontal and vertical line or block defects.

Although this can be attributed to number of different factors, including defective TFT�s and ITO (Indium Tin Oxide) corrosion, more commonly the line defect is the result of a defective TCP (Tape Carrier Package), or TAB as it is more commonly known."

Phil2008 · 11 Dec 2007 at 21:27

got the laptop today, and you are right the screen is buggered, cos if you press hard on the screen the lines disapear

But I have a bigger prob, the keybord dosent work and theres no ps2 socket to try a keyboard, but ive tried my usb g15 keyboard but nothing.

Ive looked on ebay for a replacement keyboard, but cant find one with the same model number, ect. But ive found 1 that looks the same as the 1 thats in it.

What do you think guys, should I just stick it back on ebay and try to get my money back,, cos at the end of the day, to totally fix it, it will cos at least anothe £70-80, plus it looks like someone has had ago of fixing it before me. I think it would be a cracking quite nippy laptop. But am I going to be putting too much money in to it, for what it is??

longshanks · 11 Dec 2007 at 21:59

You were dull enough to buy it in the first place mate. You should have stayed well clear!! Can't you send it back for a refund?

Phil2008 · 11 Dec 2007 at 22:08

No. Last year i bought a faulty p3 500mhz laptop for £50 that had a faulty hdd, and I fixed that for about £15, and I thought I may of got myself a bargin here too,, but it didnt work out the same way :mad:

Slinky1989 · 11 Dec 2007 at 22:11

It doesn't have a graphics card. It's an nvidia intigrated graphics chip that uses shared memory which is why 128mb of your 512 goes to it. You CAN'T reseat it.

I know this because I work at the place that it originally came from and who are the people who own the company advent

Its a ATI express 200M 128mb card in the laptop.

Like I said, it's an integrated chip. NOT a card. Just because it's made seperately by ATI doesn't mean that it's a card.

nvidia also make an integrated chip called the 6100 for example.

regarding the keyboard, its possibly the controller thats buggered, which means a new mainboard as well as lcd, and a new keyboard wont fix it.
what you need to do is using a small flat bladed jewelers screwdriver is push back the very small plastic tabs that hold the keyboard in place i think there's four along the top edge of the keyboard, as you push them back lift the keyboard up, i would leave it connected as the connectors can break easily, just flip it over, then with small phillips remove the 3 small screws and 1 large one holding in the silver ram cover, now this should reveal four small dipswitches,with the power off and battery out, push these up using flat screwdriver, now press the on button several times, take out the mains lead and push them down again, this will reset your bios defaults, plug it all back in and switch on, if you can press f2 to continue its ok, if not you need a mainboard

Ummm I kind of bust the keyboard ribbon now, cos I noticed there was a scratch running though 1 of the wires on the ribbon near where you connect it into the connector onto the laptop. So I cut off the bit where the scratch was and tried it again but still no joy, but I guess it wouldnt work now cos no wires on the ribbon are bare. But before I cut it, there was deff power going through the keyboard cos the underside gave that tinggly feeling when you touched it.

The connector on the laptop where the keyboard ribbon pushes into look a bit battered up either side of the connector where you pull apart the plastic things. Someone has been there before me. but to be honnes theres no need to pull apart the catches on the connector, cos you can get the ribbon out and in without doing that,

How do you know how to take a advent apart? You got everything right accept theres 3 big black scews in the other plate where the switches are, but I havent been under there, cos like i say ive buggered the keyboard ribbon up now

I managed to pick up a used and partially faulty Pentium-M laptop for £90, fix it up and sell it on for double the price.

I got this for £84, and if I can get it fully working it will be woth about £250, cos a Sempron 2800+ 1.6ghz, 512mb of mem (upgradeable to 2gb) is still quite fast in laptops isnt it guys?

Reasonable. Certainly is using a newer chipset, and it has a DVD-RW and onboard wireless lan.

Phil2008 · 12 Dec 2007 at 02:02

I made my mind up earlier about sticking it back on ebay, but whan I had put it all back together and cleaned it up for the pics, i was having 2nd thoughts, cos it looks dam nice all cleaned up. Im really temped to waste a bit more of my money and buy a keyboard, with 50 50 chance it will work, then if it works change the screen after xmas, then keep it for myself or sell it.

Am I being stupid, should i just stick it back on ebay and try to get back what I paid for it?

Phil2008 · 12 Dec 2007 at 10:32

I was thinking about trying the keyboard from my p3 500mhz laptop, if its the same ribbon connection, should it work? cos all the keys look the same, and theres no extra ones or missing. Good move or not?

ive repaired around 7000 laptops so have 1st hand knowledge of these, 9 times out of 10 it is the keyboard controller, so you will need a mainboard screen and keyboard, i would say these will cost you in excess of £150, plus you need to be fairly skilled to swap the parts, which could result in more damage, i would sell it and you can still make some money if you describe it well and take some good pictures,

its very unlikey the keyboard will fit, most laptops parts are specific to that model, things like hd memory and optical drives are interchangeble as are most lcd's
hope this helps

Phil2008 · 12 Dec 2007 at 22:40

Someone says if I change the inverter for the screen, that might get rid of the lines. But I cant see how that will fix the lines on the screen, if the lines disapear when you put presure on the screen?
