No encuentro mi cargador; sin él, no puedo encender mi portátil.

In Spanish, the simple present often covers what English expresses with either the present simple or the present continuous.

So No encuentro mi cargador naturally means I can’t find my charger / I’m not finding my charger in this situation.

Spanish does have a progressive form, estoy encontrando, but with encontrar it usually sounds unnatural here. You would normally use the simple present for a current problem like this.

Spanish usually uses a possessive adjective like mi, tu, su, etc. instead of an article when talking about someone’s belongings.

So:

• mi cargador = my charger
• mi portátil = my laptop

Using el instead would change the structure and usually not mean the same thing. For example, el cargador just means the charger, not necessarily my charger.

After a preposition like sin, Spanish uses a prepositional pronoun:

• mí
• ti
• él
• ella
• etc.

So sin él means without it / without him, depending on context. Here it refers to mi cargador, so it means without it.

The accent matters:

• el = the
• él = he / him / it in certain contexts

You generally need the pronoun here because sin needs an object: without what?
So sin él is the natural way to say without it.

It often means he, but it can also refer back to a masculine noun after a preposition.

Since cargador is a masculine noun, Spanish can use él after sin to mean it:

• sin él = without it

English distinguishes he and it, but Spanish often does not in this kind of structure. The context makes it clear that this is a charger, not a person.

Encender means to switch on / turn on. It is very commonly used for devices:

• encender el ordenador
• encender la televisión
• encender la luz

So no puedo encender mi portátil means I can’t turn on my laptop.

In English we might also say start up or power on, but encender is the normal everyday Spanish verb here.

Yes, portátil is especially common in Spain as a short way of saying ordenador portátil.

In Spain:

• portátil = laptop

In other Spanish-speaking countries, you may also hear:

• computadora portátil
• laptop
• notebook in some places

So this sentence sounds very natural in Spanish from Spain.

Yes. Ordenador portátil is completely correct, and portátil is simply the shorter version.

So these both work:

• No encuentro mi cargador; sin él, no puedo encender mi portátil.
• No encuentro mi cargador; sin él, no puedo encender mi ordenador portátil.

In everyday speech, the shorter portátil is very common.

The semicolon connects two closely related ideas:

• No encuentro mi cargador
• sin él, no puedo encender mi portátil

It shows a stronger break than a comma, but a closer connection than a full stop.

You could also write:

• No encuentro mi cargador. Sin él, no puedo encender mi portátil.

That is also correct. The semicolon just makes the link between the two parts feel tighter and more elegant.

Yes, you could, but the nuance is slightly different.

• No encuentro mi cargador = I can’t find my charger / I’m not finding my charger
• No puedo encontrar mi cargador = I’m unable to find my charger

Both are correct, but No encuentro mi cargador is more natural and direct in everyday Spanish for this situation.

After poder, Spanish uses the infinitive.

So:

• puedo encender = I can turn on
• puedo encontrar = I can find
• puedo abrir = I can open

This is the normal pattern:

• poder + infinitive

That is why no puedo encender mi portátil is correct.

It depends on the context.

• mi cargador clearly means my charger
• el cargador means the charger

If everyone already knows which charger you mean, el cargador might work in context. But if you want to make it clear that it is yours, mi cargador is better.

So in this sentence, mi cargador is the most natural choice.

Portátil is stressed on the second syllable from the end: por-TA-til.

The written accent shows where the stress goes. Without the accent mark, Spanish pronunciation rules would suggest a different stress pattern, so the accent is needed.

Similarly, él has an accent to distinguish it from el:

• el = the
• él = he / him / it after a preposition like here

So the accent marks are important both for pronunciation and for meaning.
