Buying a second hand laptop
It is against my religion to buy a new laptop.
However, buying second hand is fraught with difficulties for the unknowledgeable.
First rule,
Find a laptop you are happy with which is capable of what you wish to do.
When buying, note the amount of Ram & hard disk size.
You need at least 1 gig of Ram, & a 40 gig hard drive is tiny of you are into photos.
For me a Dell Latitude D505/D510/D520 series. is the beast of choice. Reason: I work in industry, & need a 9 pin serial port. These are the only readily available laptops with such a port. (Much preferred - by a long chalk, D520)
These laptops are also easily repairable, so I do not hesitate to buy a damaged one at humble money on Ebay. Often reading the fault spec. identifies the fault. E.G. Screen very dark. (Screen inverter faulty - 10 mins + £15.00 to fix)
An example of what not to buy - unless the price is superb: Laptop with dodgy power input socket. Too difficult to solder new one into motherboard. Easier to change motherboard.
One must be able to reinstall a full operating system if one buys second hand, because the systems are usually so messed up when one receives the laptop. to do this one needs the system disk plus drivers disk.
(Allow 6 hours for this - 15 minutes work & 5.5 hours waiting)
Bear in mind that many laptops are basically "throwaway", and one can buy netbooks for circa £200 & laptops for little more.
This is another reason why I tend to use latitudes. They are a full specification business computer designed to be repaired, which sell at roughly twice the price of an Inspiron (the home equivalent).
Second hand, they fetch Inspiron prices.
Be prepared to buy a new hard (larger) disk.Most second hand laptops come with relatively small ones.
This brings one back to second hand choice.
To take an example, the d520 has a SATA disk, the D505 & D510 have PATA. (The old type of drive.) They are not interchangable, & the SATA is infinitely superior, & readily available up to 1000 gig (1TB)
If buying a hard drive, in my experience, avoid Western Digital. I have had 4 master boot record failures & 1 seizure, all within 3 months of purchase. Maybe I was just unlucky, but reading Amazon reviews suggest not.
I buy lots of these types of laptops becuse I usually have to provide customers with a backup/diagnostics system when I leave site, & this is the easiest & cheapest way to do so. I just give them a cheap laptop, fully loaded with all the relevant software.
