Dell inspiron 7447 disassembly, hardware clean up and reassembly

How could you take something apart without making making notes for reassembly?!?!? Does not make sense, Shirley.

Well you can try to download from Dell their user manual - mine has a section for making repairs and disassembly/reassembly..........

If nada then you will have learned a valuable lesson when you take it to a computer repair shop for reassembly.. And save your chips because it will not come cheap since those suckers are labor intensive and ....................

Have a nice day

see p.47 of your manual

This says 3 beeps means "Possible system board failure - Chipset error" which sounds serious. Are you certain it is three beeps ? The manual recommends contacting Dell (see contacting Dell on p76). Inspect each chip on the m/b for damage (you may not find anything). You might try disassembly and reassembly of the computer (see Service Manual on Dell website) if you are competent to do this, and cleaning it out with a can of compressed air.

I suggest you open the laptop, and clean it out first. THEN go on with the diagnoses.

1) FIRST remove all power. Remove the AC adapter (Charger) and Battery.

2) FOLLOW Anti-Static Precautions.

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components on a computer.

Relieve your body of Static.

You should use an ESD wrist strap, and connect it's alligator clip to a good ground source.
This is an example of an ESD wrist strap,

This pictorial guide for disassembly of an Inspiron n5010, should help also.

The screws, and cables, etc., are in a different place, but disassembly is still the same.

Use a can, or two, of compressed air for computers.
Also you may wish to use Q-tips, and a soft small brush.
(Makeup brush? )

DO NOT use a vacuum!!!!

A vacuum creates Static electricity.

For additional questions please post in a Comment.

the problem is with the gpu inside , i suspect that overheating or continual use of the laptop for long periods has meant that the solder oints holding the gpu to the circuitboard have started to short. Chances of repairing the motherboard are slim and a replacement will be needed.

Ya seems like a hardware issue.. So tyr to run a hardware diagnostics on the laptop and see if it a hardware failure

This could be a sign that your laptop is overheating. If you touch the laptop while it is running & you find it too hot, make sure that the fan is running properly & that the air ways are not blocked.
You can blow compressed air into the cooling vents of the fan. If you notice clouds of dust coming out, then it might be a good idea to disassemble the laptop, clean the fan & air ways, & reassemble it back. If the fan has failed & is no longer running, it might need to be replaced.

If none of this solves the problem, or is not the case, then you might have a bad motherboard.

The battery has exceeded its "lifetime".

Either go to www.ebay.com to search for a replacement (original Dell battery or 3rd party equivalent).

Or, search online for companies that will take your battery, disassemble it, replace the rechargeable cells, and reassemble it, and ship it back to you.

Probably a loose connection. Disassemble, check components, the reassemble.
