Hi

A friend's laptop Lenovo won't turn on.  When you turn it on the power light turns on and is green and stays on for a while and then turns off.

They have tried removing the battery and holding down the power button for a minute to get rid of the static like in this video: https://www.youtube.com/watch?v=axgrpg-xIdE

That hasn't resolved the problem.

It doesn't make any noises when it turns on.

They were using Teams on Windows 10 when it crashed.

There are no other lights coming on when they turn the laptop on.

The Laptop is a Lenovo X220 Thinkpad and it is at least 5 years old.

Thank you if you can advise on this problem.

Andrew

The charger could be dead and the battery is flat.
You could test the charger with a multimeter or find someone who has the same charger and trying theirs.

(Good news is a new charger can be had for around a tenner)

Hi Wooster.

Thank you for your reply.

They are going to try another charger from their workplace tomorrow.

Will let you know if it solves the problem.

Thank you for your help.

Laptops are very famous for mosfets dying without any reason, but I guess you're going to have to try the charger first I'm afraid

Mosfets on a laptop isn't easily replaced without the right equipment and skill in how to get them replaced

I have three lenovo laptops and I've never had that issue.
Maybe it applies to cheaper brands.

I've come across this before and there are all sorts of magic tricks like taking the battery out (if possible), then holding the power button down for 30 seconds and also a combination on keys. none of which have ever worked for me.
Often it's the internal power supply (translated from Spanish) and I'm not entirely sure which part that refers to. As Wooster says, a different power brick is your best bet.

It's a semiconductor/ transistor.

They would have to be pretty low grade to go on a laptop that isn't overclocked or over volted.
If they're popping is down to inadequate cooling which is pretty common in laptops owed to user fault, such as sitting it on the duvet etc.

I'm doing a battery recondition on one of my survey laptops just now, it's been sitting unused for six months and only holding a 20 minute charge (as I found out today).
I doubt it'll do any good though and I have a replacement on order, when they're fucked, they're fucked.

Not all mosfets are the same, just saying

That's like saying not all shoes are the same.
They've been around since the early sixties so no doubts there are hundreds of thousands of different ones.

Hi

Thank you for your help so far.

Bad news my friend has just sent me this message after trying new charger today:

Quote
Just to let you know that the new charger has arrived and that has not worked. The green power light does not come on at all now apart from for about 15 seconds after I try removing the battery.

What do you think could be wrong with the laptop?

Thank you if you can advise.

I's probably advise looking for a new or refurbished laptop, or take it to a repair shop and see if they can figure out what's wrong with it.
Dead charger and flat battery was probably the cheapest and easiest thing to test, but now it could be any number of things.

If they find a decent refurbished one (same model), they can just switch out the hard drive and they'll have lost nothing (except some cash).

I am thinking about getting a caddy for if my computer or a friend's should not turn on to put a harddrive in to recover data, what would you suggest a separate caddy for 2.5", 3.5" and SSD one? or one device that can read various ones?  As I do some fixing myself.

Dunno mate, whatever suits you.
Unless you have some old school IDE's then all the SATA ones have the same power and data connections. They're also hot swappable (you can plug/unplug them on a running system and they pop up like you just plugged in a USB drive), so I just open my PC case and plug them in to any available connections. I leave a spare SATA data cable for this.
It's messy, but allows for quick data transfers

OK Wooster, thank you for your help. :-)

Just to let you know my friend is getting a replacement laptop from work but no news about recovering the data yet unfortunately.

There's hardly an issue with data recovery, take out the drive, plop it into an external caddy or adapter and copy the data from that drive

As mentioned, I normal just hook them up to my PC, but a 3.2" USB caddy is about £8 from Amazon.

OK thank you.

I haven't heard back what the problem with laptop is, they've probably recycled it rather than trying to diagnose the problem.

If it was a work laptop, they'd have their own methods of secure disposal.
