SMARTlife: Choosing a used laptop – first replaceable housing
In our high-tech time is not always logical to choose a new laptop. Often the reason is the high cost due to the growth of the U.S. dollar against the local currency. And the technique can literally collect «on a knee» somewhere in the co-op China and the quality may not be so hot! And you don’t always need mega-productive miracle. Sometimes it is better to buy a used, but brand laptop which will be able to work without breakdowns for a long time. But you need to learn to understand the topic or just bring the device to the service center, for example, Fixcenter, where the experts will evaluate and give an objective opinion.
But in General, the algorithm is as follows. The first thing you need to look at the screen. If the last observed dead pixels, it is better to abandon such acquisition. Definitely need to open the back cover and see the condition of motherboard. If it will be «roasted», i.e. superheated, it is better to abandon the purchase of such a dubious computer technology, as it will continue to warm up.
It should be noted that cases for laptops service center Fixcenter often change after buying equipment. This is done externally in order to obtain a new laptop. By the way, the reason for replacement housing are often mechanical damage in the fall and other unpleasant situations.
Sometimes in test mode, the laptop works, but is literally 10-15 minutes as it starts automatically disabled. The reason for this – a broken cooling fan which does not start immediately. Better to wait until you start the fan (this will be audible and noticeable) and only then to buy computer equipment. Otherwise, the next time you have to spend serious money on repairs.
You should definitely pay attention to the BIOS.
- If he is under the protection of the password, to circumvent this protection will be practically impossible. Will have to find the battery on the motherboard (it can only be a specialist) and finally to de-energize the computer equipment, when you have to install the new OS.
- Or use the buttons F12 and F8, through which the «Master» is set to DVD-ROM. If the latter is not going to work, then install a new OS via the USB port with the above BIOS will be extremely difficult, even for specialists in computer electronics. BIOS must be no password or the owner is required to give your password.
A large part of the used laptops have a weak battery. But it will not be considered a serious argument from the refusal to purchase such computer equipment. Usually it is detachable and easy to replace. Ultimately, you can always order a new battery for this model laptop, for example, in Fixcenter, or give it for restoration, with all worn-out lithium-ion cells are totally replaced by new ones. Although, according to Smartphone.ua this does not negate the need to change the notebook for a new one.
