The screen of my laptop, has some spots on the screen and some dust and dirt between the keys
What do you use for your laptop screen and keyboard to clean?
Make the microfibre cloth damp and clean the screen and keyboard. And of course make sure that you do not put too much pressure on the screen. For thicker stains very gently rub over it several times, may take a while, but spares the screen.
Keyboard: remove coarse dirt with a vacuum cleaner and a soft nozzle at a low level. With ear buds (Q-tips) you get deeper into the gaps. If individual keys then still hook, was either a sweet drink fault or the crumbs have got under the affected keyboard. Remove and clean the button. If the keyboard is hit really hard, order replacement and install. Treat monitor with monitor cleaning wipes or glass cleaner on a kitchen crepe and then wet clean and dry wipe.
I agree with all the previous speakers + I would consider removing the keys for cleaning from the keyboard. Dust, crumbs and dander love to slip under the keys and form mountains there. Removal is then simply impossible without removing the keys, until one day the keys simply stop working.
For me was in the monitor description "Do not use a glass cleaner". Therefore special Screen - Clean. Have an ASUS
If you have no glass, lt. Manufacturer could cause problems. I have never been able to determine these.
They will only secure themselves. Better is cleverer.
Do not smoke in front of a surgery, do not eat and drink only water in the last hours before. Everything to protect against lawsuits
