== Power Supply ==

The P52 is powered through a [[Power_Connector#slim_tip|Slim Tip]] connector. The USB-C ports can only supply power to other devices, they can not accept power. The P52 comes with a 170 W Slim Tip charger. It will also work on a 135 W charger, but doing so for a few weeks destroyed my 135W charger. On a 90 W charger the laptop will only charge its battery when it is in standby or off; when running, the P52 will ignore a 90 W power supply and run entirely from battery. The P52 also does not recognize a 300 W charger at all, probably because it is newer than the P52.

Over time, different ThinkPads have used different power connectors. You can use a higher Amperage rated power supply then your ThinkPad needs, as long as the physical connector is correct. But you should not use a lower Amperage power supply on a ThinkPad needing more Amperage. Doing so will overheat the power supply, and might cause issues such as screen flicker.

{{HINT|In case you cannot find your Model ThinkPad listed, or you wish to double check, you can find the required power information on a label on the bottom of your ThinkPad}}

{{NOTE|The Amperage's listed below are the OUTPUT values for the AC adapter, which should be equal or greater then what your ThinkPad requires}}

All current Thinkpads require 20 Volt DC input. See also the official Lenovo page for power adapters {{LNVDOCURL|PD014168|Lenovo Alias ID: AC-ADAPTERS, Document ID: PD014168, Last Updated :02 Sep 2016}}. (Was {{IBMDOCURL|MIGR-4tcmcu|IBM Doc MIGR-4tcmcu}}.)

The information found in this page is mostly correct. But the four-pin connector, in particular, is not thoroughly understood. This connector is [http://forum.thinkpads.com/viewtopic.php?f=6&t=112233 discussed on forum.thinkpads.com, "Correct type of power supply for 360Cs"].
[[image:4pin-power-plug.JPG|right|thumb|4 pin power connector]]

==A makeshift replacement connector==
As these 4-pin PSUs are getting more rare and more expensive, a cheap solution if you don't have one is to adapt a universal 19-20V laptop PSU with a barrel connector. This isn't ideal if you're relying on the Thinkpad for some critical old business application, but it's fine if you're just a tinkerer playing with an old one off eBay for example.

Only the "+" and "-" connections (top-right and bottom-right looking into the connector on the back of the laptop from the back of the laptop) are required for basic operation, so that's all you need to adapt.
Get an extension lead for your barrel connector - e.g. 2.1mm - and cut it in half. Discard the plug half.
Get a '''"Mini JST" plug''' with flying leads, commonly used to power model helicopters etc. This is the plug that I've found will fit over the + and - pins.
Wire the two together so that the red wire on the Mini JST is soldered to the centre contact wire on the barrel connector extension (socket half).

ALWAYS double check the polarity when plugging in your custom modded connector, since it's possible to get it the wrong way round.--[[User:Cloudane|Cloudane]]

==plug converter for universal power adapter==
[[File:4-pin_hexagon_plug_converter_S-l300.jpg|right|thumb|convertor from barrel to 4pin hexagon plug]]
An aftermarket plug converter is available, alone and in a set, which fits IBM's hexagonal inlet. It is meant to be used with an Universal AC Adapter (of cheap ''China Special'' variety). It is not safe to use. In this converter, both '''G''' and '''-''' are wired to the outer shell of the barrel connector, and both '''S''' and '''+''' are wired to the centre pin of the barrel connector. In some ThinkPads (specifically {{760E}}), '''S''' and '''-''' pins are connected to each other. This plug will make a short circuit in such a ThinkPad.

{{QUOTE|kishy|forum.thinkpads.com|Internal to the ebay DC port adapter, the (G) and (-) terminals have continuity, and the (S) and (+) terminals have continuity. Therefore, if you connect the ebay port adapter to the laptop, you are shorting positive to negative.}}

JanKanis: /* Power Supply */

== Power Supply ==

The P52 is powered through a [[Power_Connector#slim_tip|Slim Tip]] connector. The USB-C ports can only supply power to other devices, they can not accept power. The P52 comes with a 170 W Slim Tip charger. It will also work on a 135 W charger, but on a 90 W charger the laptop will only charge its battery when it is off or suspended. When running, the P52 will ignore a 90 W power supply and run entirely from battery. The P52 also does not recognize a 300 W charger at all, probably because it is newer than the P52.

{{NOTE|This page is incomplete, expect mistakes.}}
The power port is strictly used for charging and powering ThinkPads. Most newer ThinkPads do not use a dedicated power port, however. Instead, they use a USB Type-C port (24-pin) compliant with Power Delivery specifications for charging purposes.

Please note that not all power ports featured on ThinkPads are the same. Some of them are of the 'special' variety, which are not common and may be rare. For example, most IBM ThinkPads utilized the common 5.5 x 2.5 mm coaxial power connector. However, a few of them did not. One such example is the {{G40}} and the {{G41}}, which used a Singatron 2MJ-3432-007 Mini-DIN-4 connector. In some cases, an adapter can be used to work-around with an incompatible power port.

Most importantly, not all power ports featured on ThinkPads use the same voltage as well. There are some models which employ odd voltages, due to their circuitry and/or design differences. Also, this voltage difference cannot be worked around with an adapter, as most adapters are generally passive which do not modify the output voltage to match the voltage required by the ThinkPad. It is highly recommended to either use the original AC adapter meant for the said ThinkPad, or use an AC adapter with the correct output voltage. Using an AC adapter with a higher output voltage may damage the ThinkPad's charging circuit or blow a fuse and render the entire machine unusable. On the other hand, using an AC adapter with a lower output voltage may cause instability.

As for amperage, this would be the least important. However, it is still recommended to use an AC adapter with an amperage that matches the ThinkPad's amperage. Otherwise, the AC adapter may overheat (due to its circuitry being overloaded) and/or cause the ThinkPad to charge slowly (due to insufficient power). If the said ThinkPad is solely running off the AC adapter as its main power source, it will become unstable and potentially unusable. Sometimes, the symptoms could be very severe to the point that the internal display panel would flicker, or the operating system would crash (due to incorrect calculations or unstable components).

Over time, different ThinkPads have used different power connectors. You can use a higher Amperage rated power supply then your ThinkPad needs, as long as the physical connector is correct. But you should not use a lower Amperage power supply on a ThinkPad needing more Amperage. Doing so will overheat the power supply, and might cause issues such as screen flicker.

{{HINT|In case you cannot find your Model ThinkPad listed, or you wish to double check, you can find the required power information on a label on the bottom of your ThinkPad}}

{{NOTE|The Amperage's listed below are the OUTPUT values for the AC adapter, which should be equal or greater then what your ThinkPad requires}}

All current Thinkpads require 20 Volt DC input. See also the official Lenovo page for power adapters {{LNVDOCURL|PD014168|Lenovo Alias ID: AC-ADAPTERS, Document ID: PD014168, Last Updated :02 Sep 2016}}. (Was {{IBMDOCURL|MIGR-4tcmcu|IBM Doc MIGR-4tcmcu}}.)

The information found in this page is mostly correct. But the four-pin connector, in particular, is not thoroughly understood. This connector is [http://forum.thinkpads.com/viewtopic.php?f=6&t=112233 discussed on forum.thinkpads.com, "Correct type of power supply for 360Cs"].

==A makeshift replacement connector==
As these 4-pin PSUs are getting more rare and more expensive, a cheap solution if you don't have one is to adapt a universal 19-20V laptop PSU with a barrel connector. This isn't ideal if you're relying on the Thinkpad for some critical old business application, but it's fine if you're just a tinkerer playing with an old one off eBay for example.

Only the "+" and "-" connections (top-right and bottom-right looking into the connector on the back of the laptop from the back of the laptop) are required for basic operation, so that's all you need to adapt.
Get an extension lead for your barrel connector - e.g. 2.1mm - and cut it in half. Discard the plug half.
Get a '''"Mini JST" plug''' with flying leads, commonly used to power model helicopters etc. This is the plug that I've found will fit over the + and - pins.
Wire the two together so that the red wire on the Mini JST is soldered to the centre contact wire on the barrel connector extension (socket half).

ALWAYS double check the polarity when plugging in your custom modded connector, since it's possible to get it the wrong way round.--[[User:Cloudane|Cloudane]]

==plug converter for universal power adapter==
[[File:4-pin_hexagon_plug_converter_S-l300.jpg|right|thumb|convertor from barrel to 4pin hexagon plug]]
An aftermarket plug converter is available, alone and in a set, which fits IBM's hexagonal inlet. It is meant to be used with an Universal AC Adapter (of cheap ''China Special'' variety). It is not safe to use. In this converter, both '''G''' and '''-''' are wired to the outer shell of the barrel connector, and both '''S''' and '''+''' are wired to the centre pin of the barrel connector. In some ThinkPads (specifically {{760E}}), '''S''' and '''-''' pins are connected to each other. This plug will make a short circuit in such a ThinkPad.
