Lets see, where to begin... Its very little about the laptop but where do you get it fixed OR how the repair parts are gotten. Dell contracts world wide with at least three of the largest repair service groups in the world. ANY LAPTOP OR COMPUTER can become a LEMON. With DELL it seems to be who the repair person you get to do a repair...
ALL laptop screens & MOST components come from Twain or Japan.
Tosiba, you find a PLATIUM dealer(means they must carry a very large parts inventory & only 5 or 6 in USA) to buy from & get it repaired. $ for $ a great buy.
IBM StinkPad(Thinkpad) is almost bullet proof BUT their 3rd party repair has always been extremely POOR!
Compaq & HP are the same; they seem to always have a "10 cents part" mess up the works & it becomes hard to obtain to get you back up & running.
MAC's are graphics wizards but not very compatible with any windows products(90% of computer world) They are a wonderful machine but lack compatiblity you may need.
Other brands are also good, BUT the Question is, "Who has the parts to fix them?".
All computers are out of date within 3 months after purchase "rule of thumb". The newer = quicker, cheaper, & newer tricks it can perform. So look at your wallet, see what fits your need the best & buy it; do not look back, move on with it.
Computer = three parts: Display, Storage, Processor, period!!!
You look at the data, change it, & then store the data for later recall; thats all.
What you pay for:
Display = lighter, brighter, better angles view, more pixels(better picture)
Storage = Giga bytes, NO less than 80g and hopefully 160G or better
With all the available "Flash Sticks" etc; storage can be supplemented easy
Processor = SPEED!!! Best is INTEL Duel Core or Quad Core processor
Basically, it is how many task/jobs your computer can be doing at one time.
AMD, Intex Centronix, etc processors are good also but just not as fast.
MEMORY is internal to your computer & comes in several forms.
There is memory to hold data while processing it(RAM & ROM), video memory to enhance your pictures, etc.
Memory adds cost to the computer.
That you get you started...
Happy hunting...
