| 362566 | 2005-06-10 00:30:00 | My brother's brought around his (two year old) Compaq notebook which needs re-formatting, but the battery died before finishing the job and he didn't bring the mains AC power thingy. Can I use the one from my notebook to power his? I'm afraid I might fry his in some way. I've got a fairly new Asus notebook PC. Thanks for any help! |

| 362568 | 2005-06-10 01:04:00 | Ah thx Rob. I really didn't have a clue as to what info to provide. I'm absolutely hopeless when it comes to electricity! I checked the back of both and read the following: Compac input rating: 18.5v DC 4.9A Asus input: +19v 7.1A, 135 W |

| 362569 | 2005-06-10 02:27:00 | Looks OK. As long as the plug actually fits, its within 0.5v so its fine voltage wise, and its got plenty of capacity (7.1 amps, it needs to supply only 4.9 of them) so it will not be struggling. As far as I am aware there should be no polarity issues, all laptops I have seen are centre pin positive. |

| 362571 | 2005-06-10 02:55:00 | The only problem I can see is the difference between 2.1 mm and 2.5 mm DC connectors. If the PSU has a 2.1 and the computer 2.5 they won't connect withour an adaptor. If the other way round, they will connect, but make sure the DC cable is weighted down so it can't make an intermittent connection if it's bumped. (The sockets have a spring outer contact which pushes the plug "sideways" so you get a connection to the smaller inner, but it isn't perfect.) | Graham L (2) | ||
| 362572 | 2005-06-10 03:14:00 | The only problem I can see is the difference between 2.1 mm and 2.5 mm DC connectors. Bah. thx Graham - the socket vs plug doesn't fit. So I'll just wait for bro to bring around his own power adaptor. Thank you all for the advice. |
