Laptop Buying Guide: RAM, SSD and Warranty Basics

This laptop buying guide gives one short answer: for office work and study, pick a solid state drive (SSD) first, then at least 8 GB of RAM, then check the warranty in writing. A fast drive and enough memory matter more than a big brand name or a long list of extras.

Below we explain each point in plain words, so you can walk into a shop with a short list and clear questions.

1. Choose an SSD, not just a big disk

The drive stores your files and your programs. Older laptops use a hard disk drive (HDD), which has spinning parts. Newer ones use an SSD, which has no moving parts.

An SSD helps in daily life. The laptop starts faster. Programs open faster. There is no spinning noise, and the drive handles bumps in a bag better. It also tends to use less power.

The trade off is price. An SSD costs more for each gigabyte, so shops often sell smaller SSDs, such as 128 GB or 256 GB, next to larger HDDs of 500 GB or 1 TB. For documents, email, web pages and study files, 256 GB is usually plenty. If you keep many videos or photos, add a cheap external drive instead of paying for a large SSD.

Some shops sell a mix: a small SSD for the system plus an HDD for storage. That can be a good middle choice. Ask the seller exactly which drive holds the system.

2. Get enough RAM

RAM is the short term memory of the laptop. It holds the programs and web pages you have open right now. When RAM runs out, the laptop slows down.

For a basic machine, 4 GB is the lowest we would consider, and it will feel tight with many browser tabs open. For office and study use, 8 GB is a comfortable level and is our simple rule of thumb. Heavy design work or video editing may need 16 GB, but most students and office staff do not need that.

Check whether the RAM can be upgraded. Many thin laptops have the memory soldered to the board, so you cannot add more later. Ask the seller before you pay. If it is soldered, buy the amount you need now.

You may also see the labels DDR3L and DDR4 on the spec sheet. These are memory types. DDR4 is newer, and laptops built around Intel Core 6th generation chips, which began selling in September 2015, can use it. Do not pay extra just for the label. Compare the total GB, then compare the price.

3. Pick the processor by your tasks

The processor, or CPU, does the thinking. Intel Core i3, i5 and i7 are common names. For office and study, a Core i3 or Core i5 is enough. A Core i7 costs more and mostly helps with heavy tasks.

Look at the letter at the end of the model number. Chips marked U are made for thin laptops and save battery. Chips marked HQ are stronger but run hotter and use more power. For a laptop you carry to class or the office every day, U is a sensible choice.

Also look at the screen and weight. A 14 inch or 15.6 inch screen is common. If you carry the laptop daily, check the weight in the shop and try the keyboard for a few minutes.

4. Check the warranty before you pay

A warranty is the seller or maker promise to repair or replace a faulty product. In Vietnam the Law on Protection of Consumers' Rights, number 59/2010/QH12, sets out buyer rights, including the right to clear information about goods. Brands also publish their own warranty terms on their websites.

Ask these questions in the shop, and ask for the answers in writing:

• How many months does the warranty run, and does it cover the battery and charger or only the main body?
• Is the warranty from the maker or only from the shop?
• Where is the nearest service centre, and how long does a repair usually take?
• What voids the warranty? Opening the case, changing the drive or adding RAM can be a reason for refusal at some brands.
• Will the laptop come with a warranty card that is stamped with the date and serial number?

Read the maker website for the model you want and compare it with what the shop tells you. If they differ, trust the written terms and ask the shop to explain.

5. Test the laptop at the shop

Do not buy a laptop you have not touched. Switch it on and watch how long it takes to reach the desktop. Open the settings page and confirm the RAM and drive size match the label on the box.

Look for dead pixels on the screen, check every key, and test the ports, the speakers and the camera. Make sure the software that comes with the laptop is genuine, and ask what the price includes.

Keep the invoice, the warranty card and the box. You will need them if the laptop must be repaired.

Quick checklist

• SSD first, 256 GB for most people.
• 8 GB of RAM for office and study, and check if it can be upgraded.
• Core i3 or i5 with a U chip for daily carry.
• Warranty length, coverage and service centre, in writing.
• Test the machine in the shop and keep every paper.
