You have a Canon with built-in prrinter. You changed 2 what? Post cards were made mostly for desktops. You probably disturbed something when you opened the case.

"I changed 2!! service centers but nobody can help me, because my laptop is very old and repairmen can't find POST card for this laptop for diagnostic."

That's as clear as mud. Did you actually take it to computer repair places and have them examine it ?

If you removed the ram you may not have installed it so that it's seated properly.

Problems with the built in display on laptops are common. If there's nothing else wrong, if you connect a monitor to it's video port the display will be fine on that.

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

See response 1:

Some laptops will display on an extermal monitor without you having to do anything. Other laptops require that you press a key combo to toggle the display to external display / built in display - see the Owner's or User's manual for your specific model.

You are 17 years late. They were great laptops although heavy by todays standards 9lbs. See the review below. They sold well but were ahead of their time. I used them exclusively as a desktop substitute working for Canon USA We traveled often and business class travelers often handed me their card to purchase them directly from Canon. Unfortunately, in the effort to reduce weight they lost the printer.
It was an IBM thinkpad with a Canon bubble jet printer and 15.4 inch color screen and color printer. Original models were black and white printers.

The Executive Computer; Canon’s New Laptop Packs a Nice Printer Inside

SHOWING off its prowess in both printer and computer technology, Canon Inc. has introduced a powerful 7.7-pound laptop with a built-in ink-jet printer. So small and unobtrusive is the printer that the Canon Note Jet 486 looks pretty much like a normal notebook computer.

Prices will start at $2,499 when the Note Jet 486's become widely available next month.

When it is equipped with an optional facsimile modem, which costs an additional $399 or $899, depending on speed, the Note Jet 486 can also serve as a plain-paper facsimile receiver and printer. No more will executives have to trek down to the hotel lobby to retrieve flimsy documents they have sent to themselves just to get a paper copy; no longer will they have to dash to an all-night copy shop to rent time on a laser printer.

The Note Jet is also a harbinger of future generations of mobile computers that offer many features that executives now enjoy in their offices. If a laser-quality printer can be tucked inside a notebook PC, it probably won’t be long until we see built-in cellular telephones with answering machines, wireless pagers and beepers, send and receive facsimile capabilities with a built-in scanner, and even video cameras for remote teleconferencing.

But that’s the future. For today, a miniature printer that adds only two pounds and perhaps an inch of bulk to a notebook PC is impressive enough.

“It’s a pretty good deal, assuming you want to print on the road,” said Charles LeCompte, editor and publisher of The Hard Copy Observer, a newsletter published in Newton Highlands, Mass., that analyzes the printing business. “It’s a really nice printer and it can’t be much lighter. If you want a portable PC and want to print, this is the one I’d get.”

Canon has made mobile printing as easy as slipping some regular office paper into a slot under the keyboard. The keyboard actually lifts off the unit when the time comes to print.

The documents, which can include transparencies for presentations as well as standard business reports, emerge from the back of the computer at a rate of about two pages a minute. The Note Jet can also be attached to other office printers, including faster laser printers, when they are available.

Until now, traveling executives who had an occasional need for printing relied on circuitous strategies like the hotel facsimile trick. For the smaller number of executives and salespeople who routinely need printed documents — for handing a client a life insurance proposal, for example, or for giving a customer the very latest price changes faxed from the home office — the most common solution has been a portable printer, many of which are about the size of a carton of cigarettes.

But even the smallest portable printers have drawbacks beyond the obvious inconvenience of packing and carrying a second device. Many of them use special thermal paper that has a slick or greasy feel, hardly suitable for producing reports that one can hand to important clients. The Note Jet eliminates both problems. First, there is no longer a need to carry an external printer, thus saving weight, bulk, cables and power adapters. Canon’s bubble jet technology, which is an elegant variant of the ink-jet technology that forms images by spraying ink on a page, offers an impressive 360 dots per inch of resolution and uses standard paper.

Canon, or more specifically its Canon Computer Systems Inc. subsidiary (800-848-4123) in Costa Mesa, Calif., has done nothing less than eliminate the major barriers to peripatetic printing. But — and this is a pretty big but — it requires laying out a considerable sum of money for a new notebook computer. Another drawback is that both the ink cartridge and the print head, the device that controls the flow of ink onto the paper, are expensive. Replaceable ink cartridges are $8 each, and each cartridge is good for only about 60 pages. The $43 print head is good for 3,000 pages.

As a result, the cost per page is approximately 14 cents. That’s great in contrast to a hotel fax charge of $2 to $5 per facsimile page, and still great compared with what copy shops charge for laser printer pages, but it’s more than twice the cost for a page coming from a conventional portable printer.

Apparently your model is one of the Canon NoteJet series.

Searching with: NoteJet BN750 finds lots of "hits" , mostly for ram modules, batteries, and supplies for the printer.

Searching with: NoteJet finds more "hits" - I read some of them and it it appears Canon no longer has any support info or downloads for them

If you don't have a manual for it, you MIGHT be able to get one from here:

Enter a valid email address - they are supposed to email you back with a link to where you can download it.

However, I haven't received that since I did that an hour or so ago.

Update Oct 30 2011 - I still haven't received that.

Manual listings for many Canon NoteJet models, cpus 486 up to P120 (Pentium 120 mhz ?):

Your BN750 may have a 486 cpu.

The NoteJet III series has a printer, scanner, and fax capability.
