I broke two batteries due to "fully discharged". Never let the battery be discharged without some kind of monitoring. If you run Windows, make sure you set it to standby or hibernate at 2% or so. If you disable this alarm action as instructed by the IBM manual (obviously written by a non technical a...

I replaced the CF WiFi card with a USB WiFi adapter, put it as close as possible to the EVDO antenna, no problem at all. I have been using an EVDO USB modem and a PCMCIA WiFi card on this X20 for months, never a problem. The USB EVDO modem is just too inconvenient - too bulky, so I thought to replac...

With Mbai2's method, you don't need anything else. I'm going to try it out.

Update: yes, Mbai2's method works with my iPod Touch and Thinkpad X20 (XP).

I just bought a Canon K30225 CF WIFi from ebay, $15 shipped. It works fine on my X20. It is very small, only 10 mm outside and the antenna is very cool, never need to pull it up. The problem is, if also use a S720 EVDO card in the PCMCIA slot, the S720 cannot make a successful dialup. The Canon CF s...

You'll need a special WiFi device whose software/driver support access point mode. I've tried Airlink101 USB 3028 and 3026, both work and they are deadly cheap at $5.

I noticed a very interesting thing:

As long as don't use the lid switch and Fn+F7, my X20 has no problem at all - no more blocked keyboard keys, no more crash, no more missing mouse pointer.

The 900a is just a 900 with an Atom 1.6GHz CPU. Because Atom uses much less power, the battery life is doubled and heat is no longer an issue. If you want something that's smaller than X20, this 900A or 900HA is the very best choice. If you don't like slow and small SSD, then the 900HA is the one wi...

I though it might be interesting to most of us here. The only advantage of X20 is the COLD palm bay because battery (no any heating circuit) is underneath. The 900A is as cold and quiet except the palm bay that's slightly warm if I put my palms on it to let the heat build up. The 900A is in BestBuy ...

Wow, I never thought that, even though I've tried two 256MB that appear to be 128MB only. So, we might just buy a 512MB!

Got the 256MB RAM today, put it into my X20 and it works like a charm. Yes it is 8 chips total.

For those who have to have a large 12" screen, X20 is still the very best. But I want the smallest that's still usable, this 900a or 900ha is so far the only choice. Other netbooks are bigger and heavier. Smaller UMPCs are all not so perfect: OQO is a handtop only; U820's screen is too small and it ...

Got home two eee PC 900a from BestBuy for $300/ea, cannot be happier. Quieter and cooler (except the palm rest bay) than my X20, faster too, and much lighter and smaller of course, 4hrs battery life... This is the computer everyone should have one. No, my X20s are not on sale. For $100, they are sti...

I do like smaller keyboard - my fingers fly less. The 900HA is by no means a netbook, it has everything including a 160GB hard drive.

Thanks for the test, I just bought one for $25.

I've been looking for a 256MB for my X20 (2662). I've tried two, both are 8 chips, both show 128MB only.

It is ridiculous to spend $50 for 256MB for a laptop I bought for only $100. Hopefully this $25 one will work.

$400 is too much for an 1.2 GHz old laptop (even dual core), considering eee PC 900HA is only $350, lighter, smaller and longer battery life, and quiet and cold too.

I just bought a used X20. When it boots, it beeps but it starts Windows XP successfully and everything works just fine.

However, if AC is not plugged, it won't even try to load any OS and stops with this error message: Error 0198 Power source is battery.

Any idea? Thanks.

The 4MB VRAM do 1280x1024 fine. The problem is it always go back to the internal after wake up from standby. Since I updated the audio driver from IBM's to CS's (see my other thread for details), I have not encountered crash yet. I'll keep watching, if it no longer crash, then these X20 are still my...

Agree, the sound is very crispy through a good pair of speakers or headphones (I'm an audiophile).

Yes, all my PCs run WinXP.

I use one of my X21 for DVB to watch digital TV. The problem is the audio goes into buzz sound after a while and video suffers from blocks and interrupts. I upgraded the CS4281 driver from IBM's (5.1.2535.0) to CS's (5.12.1.5026), now everything is fine. So if your X2 have some strange problem, you ...

Thank Erik, that gives me a very good direction to look for an alternative. But at this moment, the Fujitsu U820 is the one in all my head. I don't need the "huge" full size keyboard; I went for X21 all because it is the only not-hot (cold actually) and deadly quiet computer I've ever touched. The U...

All my X21 are also locked to 500MHz. I would love to run Win2000 - my favorite OS, but I need the AppLocale which is only available on XP. Some of my business applications are not unicode aware, need this little converter. I would also love to run, say, Linux, but is there a QuickBooks for Linux no...

I have no problem with the performance with 384MB memory. I always clean up all the craps from my computers, so they all are very efficient with lots of memory for my applications. It is the old BIOS that has so many issues with XP. I can live with all the issues except the crash. I know X21 is too ...

Well, I love my X21 (I have 3) because they run so [censored] cold and quiet, other laptops are no compare. Performance is also decent, very smooth for all my business and entertainment applications. I love them so much, I was going to use them in all my rooms as my primary and only computer(s). I e...

I have run into the same problem with my X21. Even worse, if I extend the external monitor, my X21 (1024x768) cannot do higher than 800x600. These are not acceptable, so I dropped the idea to use an external monitor. I love X2* very much - they run so [censored] cold and quiet! However, the aged BIO...

I use the IOGear GCS42UW6, 2 USB ports and VGA monitor. Very nice cable are built in. It says the two USB ports are for mouse and keyboard, but it works for whatever I plug into them. I plug in wireless keyboard/mouse into one port and a CF/SD card reader/writer into the other, both work like a char...

Somehow I set the Fn key to be sticky in BIOS (one press and it goes into hold-down status so I don't have to hold this key down for blue keys). Now if I press the Fn key, my X21 wakes up from standby. This is very handy, in addition to the sticky Fn key feature.

Keep your X2* plugged to AC for several days to get the CMOS battery charged.

I had been waiting for a small UMPC like the EEE PC 900 until I bought a X20 from Craigslist. This thing is just too cold and quiet, a real joy for everyday computing. I force it to 500MHz and it does flash, MPEG2, VOIP all smooth. Meanwhile I'm keeping an eye on these new UMPCs for one that's as co...

I love my X20 in all aspects except one thing: often, it won't go into standby mode. After spending lots of time on this issue, I found mouse drifting is one of the causes, beside the old BIOS and video driver, and so far the only solution is this AutoIt (V2) script: SetTitleMatchMode, 2 Start: Slee...
