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.

Hi Nebi7,Thanks for posting.Battery life is estimated for the number of charge/discharge cycles.  It doesn't matter where the electricity comes from, it's the number of times it's cycled.

I want to use my old computer fan and i was wondering if its possible to power it off of an external battery. And if so whats the best way of going about it.
 

A:How can i power a fan off of an external battery?

You wouldn't be able to use a small battery like a off the shelf 9 volt. A standard fan could drain one in about 5 minutes. If you really want to I'd assume you'll need to use a lantern battery of something.

I'm wondering if there are any recommended external extended runtime battery options for the 7710 series laptop.
I see dell now has some external add-on battery options for longer runtime for the 5510 -- the Dell Power Companion 1800 mAh

but I assume it must not have sufficient output for the 17" 7700 series.
Is there an equivalent product for the 7700 series? I'd like to add 12 hours of runtime for a location that may have a few power outages a year and wouldn't mind buying a couple or few of these devices if there were one which was compatible.

Hi,I am going to use my X2 10 (10-n155sa) to travel to Africa, and while there I will be unable to have access to electricity for several days at a time to be able to charge the laptop. I need a compatable battery Usb battery pack that will allow charging of the X2 10 while on the move. I understand Hp have locked out charging from normal third party usb c battery banks with drm? (the few off the shelf third party usb c battery banks I have tried do not work, including converting usb 2 to usb c), so I am asking them what solution they have available to the problem they have created? Do they have their own Hp branded usb battery powered solution available for purchase?

I am sure I am not the only one in a similarly presented situation, with no current way to charge from a usb power bank, even if just for generic traveling without access to ac for several days. Or does anyone know of a known third party combination that allows charging of a 10-n155sa via an external usb c battery bank.

I have a strange issue. I have a Lenovo T60 laptop and I am experiencing problems with the power management/power guage.

It will often show the battery not installed (power gauge is a greyish-white color with dashed lines) or it shows a red X. It does not matter if I am on AC power or on Battery power, it will show the full range of power, battery level, not installed, or an error.

I have searched Lenovo's site and I seem to remember seeing an FAQ about this, but now that I need it, I cannot find it.

What can I check or do to stop this? While it is annoying, I am not sure if I am having a battery problem or not. I did check my battery on Lenovo's site to see if it was recalled and it is not.

I do appreciate any help that any one can give me.

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.

After my friend's laptop wouldn't run on battery power OR charge the battery I tried many "fixes."
 
Shockingly none worked that I found.
 
Only one thing worked for me to my surprise.
 
A last ditch effort was to open up the laptop (sony pcg-81114L) and disconnect the cmos battery for a few minutes to reset the CMOS.
 
To my surprise, when powered on, the battery instantly showed it was charging AND when removing the power plug the battery POWERS the laptop now! (and I'd thought I was wasting my time.)
 
Worked with an off brand battery also.
 
Many times this has saved many computers that have odd "unsolvable" things wrong with them.
 
Surely someone else has done this also but I haven't seen it posted anywhere to my knowledge.
 
Thank GOD for bringing the idea to remembrance!

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.

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 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.

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.
