There are a lot of bargain laptops for sale, but many use old technology that you should avoid. Watch out for laptops with:
1. less than 4 GB of RAM, a trick Apple Computer uses to cut costs.
2. Celeron Processors
3. Parallel ATA hard dives.
4. other 32-bit processors
Modern laptops and PCs use 64-bit processors such as the AMD x86 64 bit processor. These processors can address up to 8 MB or RAM while 32-bit processors can only address 4 GB.
The Celeron technology works with all 32-bit processors, but not with all 64-bit.
Celeron processors can run all IA-32 computer programs, but their performance is often significantly lower when compared to similar CPUs with higher-priced Intel CPU brands. For example, the Celeron brand will often have less (L2) cache memory, or have advanced features purposely disabled. These missing features can have a variable impact on performance, but is often very substantial.
It gets worse because the older laptops use the parallel ATA hard drives that are slow. Modern hard drives are Serial ATA hard drives that run at 7200 RPM instead of the older PATA speeds which run at 5400 RPM. The newer SATA controllers also improve HD performance
The new SATA drives do not use a ribbon cable to connect to a laptop or a PC. Both the power supply and data cables are different on the newer HDs,
