Greetings from Portugal. I'd just like to say that i've found a powerbank that can be used with the 900s (and probably others that use the same charger). The one i found, and can confirm charges the laptop, is "RAVPower 27000mAH Powerstation" that i found on amazon.It's a powerbank with a regular power plug to connect the charger, so it could be called a mini ups instead of a powerbank. Hope this helps people looking for something similar.

You can find a huge collection by searching ?power banks for laptops? on a search engine. You just need to compare things like capacity, weight, and price.  The power bank should have a USB standard charging port and a DC output port as well.

Has anyone tried this or have a story to tell about power banks?My relatively new X1C does quite poorly on battery if I'm doing real work, e.g. compiling and running apps with Visual Studio & SQL Server.  Fiddling with the battery settings doesn't make that much of a difference so I thought why not carry a brick with me when on the road? I'm just starting to look into it but real stories from real users are just so much better than generic 'reviews' or hidden adverts that have become all too commonplace in the last few years.

A:Yoga 3 Pro / UNIFUN power bank

Good day and welcome to the community.
 
The Yoga 3 Pro looks for 20V input, 4x what that power bank can output. Also, the proprietary cable has extra contacts.
 
There may be power banks that can supply the proper voltage, but I think it unlikely that one has the proprietary receptacle configuration to match the cable.

Hi all, got this power bank (40AL140CWW) for my P1. It is listed as acceptable for the system on the Option Compatibility Matrix (January, 2019). Got it a while back, tested it, worked fine: https://www.reddit.com/r/thinkpad/comments/9uyew4/fieldtesting_the_lenovo_usbc_14000mah_power_bank/ Using it today (charged yesterday) ... all four lights on the bank come on when I plug it into my P1, but, the system is behaving differently ... previously, the bank powered the unit and its LEDs went off one by one as the charge decreased; the main battery indicator on the bottom did not move off 95%. This time, the main battery indicator shows a decreasing level of charge, and so far, the bank still has four LEDs illuminated. Even weirder, the "remaining time" at one point seemed to indicate the battery was present (showing 8+ hours remaining) but now, even that has changed, and the system is acting like there is no power bank installed at all (shows 3 hours and 33 min [77%] remaining.) I am using the USB-C power cord that came with the bank. Is it defective? TIA, -kj-

Hello,

This problem is from a friend of mine but he doesn't has a computer now. Yesterday he was charging his powerbank through his Laptop (Asus bought 3 months ago) USB port. After a while the computer was shutdown and won't turn on, even when it's plugged through its power adapter.

Is there any solution to this?
Thanks!
 

A:Laptop wont turn on after charging power bank

Hi and welcome to TSG.

As annoying as it can be to have to do it, your best option if it appears totally dead is to RMA the laptop if it is only 3 months old. Fiddling about with it too much trying to diagnose the problem could end up invalidating any warranty your friend has.

The only simple checks I would do are to try and power it up with and without the power cord connected.
Then remove the battery (assuming it is a removable one) and try it again with the power adapter attached.

It could be a problem with the laptop or that the power brick has just failed, it happens occasionally.

Hello Everyone, I am considering the purchase of a specific power bank for my L540 laptop. The product is the Vinsic 30000mah. I can't seem to get clarification on whether my Lenovo laptop will successfully hook up with the PB and take the charge. As far as I can tell, the PB has a lot of muscle and is well-recommended. The PB comes with 8 adaptors; for Lenovo products it lists a  7.9*10 mm adaptor. It says it has 3 output ports: 1 DC output up to 19V 3.5A, with a max output current of 4.5A; and 2 Smart USB outputs, with output up to 5V 2.4A.  It also says it has 2 Input ports: 1 DC input and 1 Micro USB input. I am uncertain if the specs on my L540 make it compatible with the features listed shown above. Can someone with expertise advise me if I'm Ok to go ahead with the purchase based on the features? Many thanks!

Hi, I just bought AC Outlet Portable Charger RAVPower 27000mAh 85W (100W Max). The AC adapter of my ThinkPad T480 is rated at 65W max.

Hi Blockie,

I'm not aware of anything that will power-down a USB drive completely, but Windows does have a function to suspend power to the USB port, thereby conserving some power. If the device requires power again, the port will automatically be turned back on again

was using pc last night and the surrounding area lost power supply.
Had a gut feeling some damage will occur. I was right, looks like everything is working apart from the ssd booting. at boot up it goes through bios screens etc and then a black screen with reinsert boot media device(or words to that effect), so i went into bios and my secondary hdd is showing along with a dvd drive though have 2(will double check,1 aint damaged) in the boot menu but no sign of the ssd.
So obviously im assuming a new ssd is needed, but could i be in luck and something else is preventing boot.
Longshot that its something other than a defunct ssd, with a new one i suppose the only option is a clean install.

While im here any recommendations on a UPS, and btw my system did have surge protection if its relevant

So it was working the other day, I left my computer, came back, and it wasn't showing up. I restarted the computer and it was not showing up at all. It is definitely getting power, but it is not showing up in the remove hardware option in the bottom tray, it is not making the sound when it get plugged in, and it is not showing up in the disk management or whatever it's called.

I've tried on different computer and am having the same issue. Earlier today I plugged it in and after 20 mins or so it showed up with notifications and everything and was able to open some folders but it started saying there were delayed write issues and wouldn't let me open anything else. After that nothing for a few more hours then I went to try it on a different computer and it showed up only in the remove hardware thing at the bottom. Not in the explorer nor in the disk management thing.

It's still under warranty so I can replace it, but I have about 600 gb of pictures music and movies that I probably will have an extremely difficult time getting back without spending hundreds of dollars.So I don't want to switch it out unless I have to. Please help I'm spending a lot of time trying to fix this!! Any help would be much appreciated.

Get the new hard drive and install Windows on it. After you have applied all the Windows Updates, install the old drive as a second hard drive and see if you can access files from it that way. If you have to return the old drive for warranty replacement, see if you can borrow a drive for this data transfer. If the old drive isn't seen, there is nothing that can be done to save the data short of spending hundreds of dollars
